If your elbow aches after a session and you are not sure whether it is the racquet, the technique or the strings, the strings are the piece you can change in about an hour. We went through twelve of the most-reviewed tennis strings on the market and ranked them specifically for the best tennis strings for arm pain, not for spin or serve speed. Two ideas did most of the work: string stiffness, which decides how much of the ball’s impact energy the bed absorbs instead of passing into your forearm, and string tension, which multiplies whatever the material does.
Before the list, the short version. A soft string at a sensible tension will not cure lateral epicondylitis, and nothing you string will. What it can do is lower the load going into a tendon that is already irritated, which is usually enough to let you keep playing. Most players who come back from elbow trouble tell us the same thing: the pain returned the first time they went back to a stiff polyester bed, not because polyester is bad, but because it was still the wrong tool.
We also found a gap in what is available on this topic. Most guides stop at the four string families and never name a product, so you finish the article knowing that nylon is softer than polyester but with nothing to restring with. Everything below names a specific string, a specific gauge, and the tension range we would actually ask a stringer for.

1. HEAD Velocity MLT – The Most Consistently Comfortable String We Tested
Head Velocity MLT Tennis String (17, Blue)
Polyamide co-polymer monofilament
17 gauge 1.25mm
40 ft set
#1 in Amazon Racket String
Pros
- Low-stiffness build that softens impact on the elbow
- Highest review volume in the group at 826 ratings
- 85% of ratings are 5-star
- Available in 16 17 and 18 gauge
Cons
- A minority of players find the feel too muted for their game
- Loses some control precision versus a polyester
This is the string we come back to. It carries 826 ratings at a 4.7 average, the largest evidence base of anything in this roundup, and 85% of those ratings are five stars. That consistency matters more than the headline number, because arm-friendly strings tend to polarise: the players who love them love them, and the players who want a firm response with a net feel simply are not the target.
Technically it is a polyamide co-polymer monofilament, which reads like a contradiction until you hit with it. The construction is a monofilament, so it has a defined, consistent response rather than the mushy warmth of a nylon multi, but the polyamide base keeps it in a much lower stiffness band than any polyester here. It is 17 gauge at 1.25mm as a set, and it comes in 16, 17 and 18 if your stringer recommends a different thickness for your frame.
Our practical read: for someone whose elbow is complaining and who is not a control obsessive, this is the default. We would put it in at 52 to 56 lb in a modern player’s frame and 46 to 50 lb in a light 285g racquet, always within the frame’s own tension chart. Those numbers sit inside the range that the frame manufacturer approves, so you are not exceeding a stiffness or load limit the racquet was not designed for.
What you give up by stringing it softer
Control depth and directional precision are the two things that move first. A low-stiffness monofilament at reduced tension gives you a larger, more forgiving sweet spot, but a flatter, less precise ball flight at the net and less shape on a high ball. For a recreational or club player that is a fair trade. For a tournament player who lives on short angles, it can feel like the ball is doing something the string is not asking for.
There is also a smaller camp of reviewers who simply find the response too soft, and they rate it accordingly. The 15% of ratings that are not five stars cluster in that group, and it is not a defect. It is a fit issue. If you generate pace and rely on string tension for control rather than on racket head speed, one of the polyester options further down this list will suit you better.
Who should skip it, and who should buy two reels
Skip it if your game is built on heavy topspin with a high launch from a stiff modern frame, or if you already have zero elbow symptoms and want maximum spin potential. This string is not trying to be Luxilon, and it will not compete with a good polyester on spin grip.
Buy it if you are a frequent stringer or you restring for several people, because the set format and the wide gauge range make it easy to standardise. It is also the safest first string to hand someone who has never thought about string tension at all, which is exactly the group most likely to be playing with a stiff, inappropriate bed right now. We have seen this string recommended directly in arm-pain threads on the tennis forums for precisely that reason.
2. HEAD Lynx Tour – Spin and Control With a Softer Polyester Edge
HEAD Lynx Tour Tennis Racket String, 40′ Set, 17G, Champagne
6-edge co-polyester monofilament
16 17 and 18 gauge
40 ft set
Intermediate to advanced
Pros
- 6-edge design delivers real spin bite and precise placement
- Co-polymer blend improves tension stability and durability
- Stays comfortable through long sessions
- One 40 ft set strings a full standard racquet
Cons
- Firmer than any comfort-first option in this list
- Less feel than a multifilament for players who swing fast
The Lynx Tour sits in the awkward middle of this roundup, and that is exactly where it is useful. It is a co-polyester monofilament, so it belongs to the stiffest family on the page, but the 6-edge cross-section geometry and the co-polymer blend pull it toward the softer end of the polyester range. It rated 4.6 across 423 reviews with 78% five stars, so the response is consistent rather than surprising.
Why include it in a roundup about arm pain? Because the honest answer for many players with a sore elbow is not to abandon polyester. It is to abandon a hard poly at a high tension. The Lynx Tour lets you keep a spin-capable bed and drop the tension, which forum players describe as a much easier adjustment to make than switching families entirely. If you have played a stiff poly for years, this is the lowest-friction step down.
We would string it at 48 to 52 lb in a player frame, and 2 to 4 lb below whatever tension you used before. As with every number on this page, the frame chart is the ceiling, not the suggestion. If your racquet’s chart tops out below that range, follow the chart.
Why the 6-edge shape matters for a tired arm
The six flat edges do two jobs at once. They bite the ball, so you get spin generation from a slightly lower swing speed, and they stiffen the string laterally, which makes the bed hold tension more consistently. For an arm, the second part is the one people miss: a string that loses tension quickly turns a firm bed into a dead, unpredictable one, and a dead bed is not comfortable even at a low poundage.
The trade is that lateral stiffness comes with more impact shock. This is a co-polyester, so it transmits more energy into the forearm than a nylon multi at the same tension and gauge. It belongs in the arm-pain roundup as a controlled step, not as a soft option. Players mid-flare should not start here.
When this is the right call, and when it is not
Choose it if you are an intermediate or advanced player with a mild ache, you want to keep serve speed and spin, and you are willing to actually lower the tension rather than just switching strings at the same number. It is also a sensible upgrade path from a generic supermarket poly, since the co-polymer blend holds tension better over a long season.
Pass if you have genuine lateral epicondylitis symptoms, if you play on a racquet under 285g, or if you tend to play with a lot of wrist and forearm involvement rather than a stable kinetic chain. In those cases a nylon multifilament is the better first move. If you already know polyester is what makes your arm hurt, this is not the string that will change that.
3. WILSON NXT – The Reference Multifilament With a Measurable Shock Claim
WILSON NXT Power 40-Feet String, Natural, 16
35% polyurethane by volume
X-bonded core
16 gauge
Set or 200m reel
Pros
- Manufacturer claims 74% less shock than traditional synthetic gut
- 10% larger sweet spot for off-centre hits
- Reviewers repeatedly cite elbow wrist and shoulder comfort
- X-bonded core improves tension maintenance and power
Cons
- Fraying and snapping reported within weeks to a couple of months
- Some argue it behaves more like coated nylon than a true multi
- Loose packaging lets the reel unwind
Wilson NXT is the most widely recognised arm-friendly string in tennis, and the reason is unusually concrete. The manufacturer publishes a 74% reduction in shock compared with traditional synthetic gut, which is a specific, checkable claim rather than a vague promise of comfort. The construction is 35% polyurethane by volume over an X-bonded core, and the same core is credited with improved tension maintenance and power.
It rates 4.5 across 445 reviews. The dominant theme in that feedback is comfort, and more than a few owners describe switching to it specifically because of elbow, wrist or shoulder problems. NXT is also the string most often named in tennis forum threads when people ask for an arm-friendly recommendation, alongside the HEAD Velocity MLT.
For tension, we would run it at 50 to 55 lb in a modern player frame, which is roughly 4 to 6 lb below a typical stiff poly setup. NXT also comes in 16 gauge as listed, and the wider 200m reel option is genuinely useful if you are a club stringer or you want a setup you can build hybrid crosses with.
Be honest about the break-in rate
This is where NXT loses points, and it is worth being blunt. The recurring complaint across reviews is durability. Players at three or more sessions a week describe fraying or snapping within a few weeks to a couple of months. If you break strings anyway, that is a cost line. If you never break strings and play twice a month, it is irrelevant.
There is a second, subtler cost. Some reviewers argue that the polyurethane coating makes NXT behave more like a coated nylon than a true multifilament, which means it can feel slightly more defined and slightly less plush than a natural multi. It sits between the extremes rather than at the soft end, and players who are genuinely mid-flare sometimes find they want something softer still.
Who this string is built for
NXT fits three groups well. Beginners and juniors who are still developing a consistent swing and often play on lighter frames. Senior and recreational players who want power without stiffness. And established players who want one dependable arm-friendly string they can keep in a rotation for the whole season without thinking about it.
It is the pick if you want one change that solves several problems at once and you are willing to accept a shorter string life. If your priority is the lowest possible load on the forearm, look at the Tecnifibre X-One Biphase or the two natural gut options further down. If your priority is the least expensive way to take the edge off, the Tourna Synthetic Gut Armor covers that instead.
4. Solinco Hyper-G Soft – The Softest Polyester in the Lineup
Solinco Hyper-G Soft Tennis String Set (16)
Co-polyester monofilament
16 16L 17 and 18 gauge
40 ft set
Soft feel profile
Pros
- Soft-focus co-poly profile lowers stiffness against harder polys
- Widest gauge range here with 16 16L 17 and 18
- 4.6 rating across 394 reviews with 76% five-star
- Popular with competitive juniors and doubles players
Cons
- Still a monofilament so softer than a real multi only
- Strung high it loses its soft character
- Some 3-star reviews cite imprecision for their game
Here is the marketing trap made concrete. The Hyper-G Soft is called soft, and relative to a Luxilon or a heavy co-poly it genuinely is. Relative to a nylon multifilament, it is not soft at all. If you are shopping an arm-pain roundup and you read the word soft on a polyester, the label is telling you about the family, not about your elbow.
With that caveat in place, the Hyper-G Soft is a good product for a specific job. It rated 4.6 across 394 reviews with 76% five stars, and buyers describe it as a softer-feeling polyester with respectable control and spin. It is widely strung by competitive juniors and doubles players, which is a group that tends to want a defined response without a locked-up arm.
The gauge range is the practical star. It comes in 16, 16L, 17 and 18, and 18 is the thinnest option in this entire roundup. Thinner string at the same poundage deforms more on contact, so an 18 gauge version of a given string is the gentlest way to run it. If you like the spin of a poly but your forearm is unhappy, asking your stringer for the 18 is a cheap, underused lever.
I would string this at 46 to 50 lb, and lower it further if the tension chart allows. Run it higher and the soft character largely disappears, which defeats the purpose entirely. This is the string that most needs a genuine tension drop to justify itself on an arm.
When a soft poly is genuinely the right answer
Two situations. First, you are moving down from a hard polyester and you want to keep some spin bite without a full family switch. A soft poly at 48 lb feels very different from a hard poly at 56 lb, and the difference is often enough. Second, you dislike nylon multi because you think soft strings make you play badly, and you need a compromise that keeps some edge.
That second case is the more common one. Players abandon soft strings because losing spin feels like getting worse at tennis, then the pain comes back. A soft poly gives you a response shape closer to what you are used to while still taking the sting out, which is a reasonable psychological trade when you are not ready to go all the way to a multi.
Where it stops helping
It stops helping the moment you are in a genuine pain cycle. A monofilament transmits more impact shock than a multifilament at any comparable tension, and no amount of soft-focus branding changes that physics. The reviews reflect it too: several three-star ratings describe a feel that is imprecise, and the recurring caveat in the feedback is that this is not the softest choice in the list for existing arm trouble.
Also be careful with tension. Strung at the upper end of the range, the Hyper-G becomes a firm polyester, and you have changed the string brand but kept the problem. If your plan is to restring into this string, decide the poundage first and let the stringer work to it.
5. HEAD Hawk Touch – Built for Coaches and High-Volume Restringing
HEAD Lynx Tour Tennis Racket String, 660′ Reel, 17G, Champagne
6-edge co-polyester
17 gauge 660 ft reel
16 17 and 18 gauge options
Control and spin focused
Pros
- 6-edge co-polyester bites well for spin
- Co-polymer blend improves durability and tension stability
- 660 ft reel covers many restring jobs
- Made for advanced players with hard swings
Cons
- Much firmer than any comfort-first string here
- Reel format is impractical for a single racquet owner
- Can feel stiff at higher tensions
The Hawk Touch is in this roundup for a structural reason rather than an arm-comfort one. It is the 660-foot bulk reel option, and for anyone who strings for a club, a team, or a group of friends, having a polyester on hand that holds tension is worth more than any single comfort upgrade. A 4.6 rating from 255 reviews with 81% five stars tells you the reel itself is well received, and the buyers are largely coaches, stringers and advanced club players.
The construction is a 6-edge co-polyester with a co-polymer blend for durability and tension stability, aimed squarely at the advanced player who generates real racket head speed. That audience is not who this article is for. We include it so that a stringer reading this can see clearly where the comfort range begins and ends, and this is well outside it.
If you do string with it, treat it as a high-tension control string. Somewhere in the 50 to 56 lb band in a player frame, following the chart. For an arm-pain case, do not.
Why durability is the whole point of this reel
Co-polyester blends resist fraying and hold tension through long seasons, which is exactly what a busy stringer needs. A 660-foot reel represents a large number of racquets, and if each one keeps its tension for a reasonable stretch, the amortised cost per job is the lowest of any polyester here. That is a genuine advantage, just not an arm advantage.
It is also worth noting the tension-stability point as an indirect comfort factor. A bed that holds tension stays predictable, and a predictable bed is easier on the forearm than one that goes dead and erratic. But that only helps if your starting tension is low enough in the first place.
Who should buy it, and who should not
Buy it if you run a stringing business, coach a squad, or just restring several frames a month and want one dependable poly. The reel format rewards volume and punishes anyone restringing one racquet a year, which is the honest limitation of this product.
Do not buy it if you have elbow pain, play on a light frame, or are a beginner. It is explicitly designed for harder punches, and a minority of reviews note it can feel stiff at higher tensions. For arm comfort in a bulk format, the Kirschbaum synthetic gut reel later in this list is the version of this idea that actually suits you.
6. WILSON Natural Gut – The Softest Thing on This Page
Wilson Natural Gut 17 Tennis String – Set, White
Natural serosa gut construction
16 and 17 gauge
15% durability improvement
Protective outer coating
Pros
- Softest arm feel of any string in this roundup
- Excellent tension maintenance over long periods
- 15% durability gain over previous versions
- Outer coating makes installation easier
- Suitable for all skill levels
Cons
- Premium priced for a full gut bed
- Moisture sensitive and needs careful handling
- Plays powerful so some players need a higher tension
True natural gut is made from serosa fibres twisted together and coated, and it is the softest string material available for a tennis racquet. Wilson’s version rated 4.5 across 215 reviews with 75% five stars, and owners consistently point to feel, control and tension stability. For a player with an already-irritated elbow, this is the reference point for the lowest possible load.
Two things make it work as a recommendation rather than an indulgence. The first is tension maintenance: gut is unusually good at holding its tension over time, so the bed stays consistent and predictable instead of drifting. The second is the protective outer coating, which exists mainly to make installation easier and reduce handling damage, and it also means a slightly tougher string than old-school untreated gut.
Tension is the one place gut needs care. Because it produces so much free power, a gut bed at a low tension can feel uncontrollable for players used to a firmer response. Several reviews advise stringing it 3 to 4 lb higher than your normal number rather than lower, which is the opposite of the usual instinct. We would start around 54 to 58 lb in a player frame, within the chart, and adjust from there.
The cost question, honestly
Natural gut sits at the premium end of the cost range for a full bed, and the reviews are candid about that. For a player who restrings two racquets a year that is a manageable line item. For someone who restrings four frames every three weeks because the strings keep snapping, it is a bad financial decision, and the string will not last long enough to justify it anyway. Gut is durable in the sense of holding tension, not in the sense of surviving a heavy-handed server.
There is a practical workaround that costs almost nothing. Use gut as the cross string only, over a cheaper main, and you get most of the arm benefit at a fraction of the outlay. A couple of players on the tennis forums describe exactly this arrangement, using a soft cross string as the fix that got their elbow issues to settle.
Who should buy real gut, and who should not
Buy it if you have a recurring elbow problem, you can restring a few times a year rather than monthly, and you want the softest legal-feeling bed available. It is also the natural choice if you play a mostly flat, feel-based game on a head-heavy frame, where gut’s power and control blend works in your favour.
Skip it if you play in a humid climate and store your racquet in a car or a shed, because gut is moisture sensitive and will lose its character. Also skip it if you are a heavy topspin player who needs the ball to dip and bite. In that case the Luxilon natural gut later in this list, with its hybrid-optimised coating, or a soft polyester will serve you better.
7. Kirschbaum Reel Synthetic Gut – The Best Cross String Here
Kirschbaum Reel Synthetic Gut Tennis String, Natural, 1.30mm/16-Gauge
Refined synthetic gut construction
Reel format
1.30mm 16 and 1.35mm 15 gauge
Model SG 130
Pros
- Tied for the highest rating in the roundup at 4.7
- Classic arm-friendly feel without natural gut pricing
- Works well in hybrids with Kirschbaum polyester
- Reel format gives good value for frequent stringers
- Made in Taiwan with quality control standards
Cons
- Only 201 reviews so a smaller evidence base
- Reel is more than most single-racquet owners need
- Listed as mens-oriented in the product data
Kirschbaum’s synthetic gut shares the top rating in this roundup at 4.7 across 201 reviews, with 79% five stars. That is a smaller evidence base than the HEAD Velocity MLT has, so we treat it as a strong result rather than a proven one, but the feedback is consistent: owners like the feel, the hybrid versatility and the value of the reel format.
The reason it earns a place in an arm-pain roundup is the class of string it belongs to. Synthetic gut was invented as a cheaper, more durable imitation of natural gut, and it succeeds on exactly the property that matters here: it is soft, it is arm-friendly, and it does not command the price of real gut. It is listed in 1.30mm 16 gauge and 1.35mm 15 gauge, so you can step up in thickness if you want more control or down for more give.
It is sold as a reel, which is the real caveat. If you own one racquet, a reel is far more string than you will use in a year. If you string regularly, or you run a club, the reel format makes this one of the better value options per job in the whole list.
Why this is our preferred cross string
A good cross string does two specific things in a hybrid. It softens the bed, because crosses are where a large share of the impact energy is absorbed, and it adds grip through its surface friction. Synthetic gut is genuinely good at the second job, which is why stringers reach for it or for a similar slippery synthetic when they want a cross that bites without adding stiffness.
Forum players describing the classic arm-friendly hybrid frequently name synthetic gut and spiral-style polyamides for the crosses for precisely this reason. The Kirschbaum is also listed as hybrid-compatible with Kirschbaum polyester mains, so if you want a matched pair from one brand this is the one to look at.
Who it suits and who it does not
Suit it if you string more than a few racquets a year, if you want a cross string that adds feel and bite at a sane price, or if you want a full synthetic gut bed without paying natural gut money. It is also a good full-bed choice for a player with a sensitive arm who does not want the extreme softness of real gut.
Do not suit it if you want a single racquet set and do not want to store a large reel, or if you need a string with a very large public review record. Two hundred and one reviews is a good signal, not a guarantee, and the listing is also flagged as mens-oriented in the product data, which is worth noting if that matters to you.
8. WILSON Sensation – The Gentle Pick for Seniors and Juniors
WILSON Sensation 40-Feet Set, Natural, 16
xycro microfibres with DuPont polymer bonding
16 gauge
40 ft set
Vibration dampening characteristics
Pros
- Microfibres with high strength-to-weight ratio for comfort
- Favourable vibration dampening helps the elbow and shoulder
- DuPont bonding adds strength without stiffening
- Original high-performance multifilament
- 81% of ratings are 5-star
Cons
- Smaller review base at 151 than other Wilson multis here
- Softer feel means less control and power than a polyester
- Some 3-star ratings cite softness that reduces precision
The Sensation is the older, softer sibling to the NXT, and for a lot of players it is the better choice. It is built from xycro microfibres with a very high strength-to-weight ratio, bonded with a DuPont polymer, and the manufacturer specifically calls out favourable vibration dampening characteristics. That is 4.6 from 151 reviews, with 81% five stars.
For arm pain, the dampening characteristic is the number one reason to consider it. Of all the properties on this page, vibration is the one the Sensation is explicitly engineered to reduce, and while vibration is not the same as impact shock, a bed that rings less feels better on every single stroke. It is the softer of the two Wilson multifilaments, which means it is the one to pick if NXT still feels firm to you.
Tension-wise, we would start at 48 to 52 lb and follow the chart. Because it is a 16 gauge set, that is already a thinner string than most of the polyester options here, and thinner string deforms more on contact, which works in your favour on a tender arm.
Where the Sensation fits against the NXT
The two Wilson multifilaments are not competing for the same player. NXT is the more defined of the pair, with a polyurethane coating and a slightly firmer response, and it suits a player who wants a bit more structure while still avoiding polyester. The Sensation is the softer one, with an emphasis on comfort and vibration control, and it suits a player who finds the NXT still too much.
That is the useful framing. If you have tried a mid-range multifilament and it still transmitted too much, step down in softness rather than sideways in brand. If a nylon multi has never occurred to you and your arm is already complaining, either one will do, and the Sensation is the gentler of the pair.
Best fits and known limits
This string suits senior recreational players, juniors still building a swing, and anyone who wants a soft bed with a genuine strength-to-weight story behind it. It is also a good full-bed option for a player on a light racquet, since the softer material protects a frame that would otherwise be working hard.
The limits are honest ones. The softer feel means less control and less power than a polyester for aggressive players, and a handful of three-star reviews cite exactly that loss of precision. The review base of 151 is also the thinnest among the Wilson strings here, so treat the 4.6 as a good signal from a smaller pool rather than a certainty. If you need more bite from a hybrid, pair it as a cross rather than a main.
9. Luxilon Natural Gut – The Natural Gut Built for Hybrids
Luxilon Natural Gut 125 Tennis String – Set, White
9 serosa ribbons
Low-friction hybrid-optimised coating
1.25mm and 1.30mm
Organic grass-fed collagen
Pros
- Nine serosa ribbons hold tension better than a typical gut build
- Coating specifically optimised for hybrid setups
- Excellent ball pocketing and a balanced feel
- 83% of ratings are 5-star
- Performs well as mains in a traditional hybrid
Cons
- Premium price per set
- Lots of free power so some players string 3 lb higher
- Better suited to traditional swings than modern spin play
The Luxilon natural gut is built differently from the Wilson version, and the difference matters for hybrids. Instead of a standard ribbon count, it uses nine serosa ribbons, which the manufacturer credits with better tension maintenance, and it carries a low-friction coating that is specifically optimised for hybrid play. That coating is the reason it sits in this roundup at all: it is designed to be paired with something else.
It rated 4.6 from 123 reviews, the smallest review base of the twelve, but with 83% five stars, the highest five-star share in the group. Owners overwhelmingly hybridise it with a soft polyester in the crosses, and they praise the control, power and comfort balance along with how well it holds tension. Recurring advice is to string it a few pounds higher than usual to rein in the free power.
The organic grass-fed collagen is a feel story rather than a measurable one, but owners consistently report excellent ball pocketing. On a 1.25mm or 1.30mm build this is a fine, thin gut, so it is not the most protective of the natural options if you hit hard with off-centre contact.
Why mains rather than crosses
Gut in the mains gives you the arm benefit where the load is highest, and it also gives you a bed that holds tension well, which keeps the hybrid predictable. The low-friction coating is what makes this practical: it grips the string it crosses rather than sliding against it, so the two strings interact as one bed instead of two independent ones that move against each other.
If you build a hybrid with these as mains, we would string the mains at 54 to 58 lb and the crosses 2 to 4 lb lower, staying inside the frame chart throughout. That structure, soft and arm-friendly cross under a gut main, is the configuration that shows up most often in tennis forum threads about elbow-friendly setups.
Where it fits and where it does not
Suit it if you want the softest possible main string but play a traditional, feel-based game, and if you are comfortable building or requesting a hybrid rather than asking for a full gut bed. It is a good fit for players whose swing path produces shape rather than pure launch.
Do not suit it if your game is built on modern heavy topspin, since the reviews note it favours traditional swing styles. It also commands a premium price per set, and with 123 reviews the evidence base is the thinnest here. If you want real gut as a full bed without fussing with tension deltas, the Wilson natural gut is the simpler buy.
10. Tecnifibre Triax – A Soft Multi-Filament Build With Genuinely Mixed Reviews
Tecnifibre Triax Natural Tennis String (16 Natural)
50% co-polyester and 50% polyamide
Multi-filament construction
Gauge 1.33mm
12m length
Pros
- One of the softest options in the roundup
- Repeatedly recommended by owners for arm problems
- Good tension stability with no movement after 20+ hours
- Works as a full bed or as a cross over poly mains
- Generates free spin and power
Cons
- Lowest average rating here at 4.4 with 8% one-star ratings
- Some owners report very early breakage
- One review reports almost no spin generated
The Triax is the most polarised string in this roundup, and we would rather show you that than hide it. It rated 4.4 from 120 reviews, the lowest average of the twelve, and the split is stark: 75% five stars against 8% one stars. Enthusiasts describe it as soft, plush, arm-friendly, durable and spin-generating. Detractors report early breakage and, in one case, no spin at all.
What makes it technically interesting is the construction. It is a multi-filament built from a 50% co-polyester and 50% polyamide blend, which is a different recipe from a pure nylon multi. That blend is what gives it good tension stability; one owner reports no string movement after more than 20 hours of play, which is unusual for a soft string. It is made in France and comes in 1.28, 1.33 and 1.38mm.
Durability is the dividing issue and the deciding factor. Enthusiasts report roughly two months for a player hitting it two or three times a week. Detractors report a break in about six hours, and some recreational players see it go at around three weeks. That is a wide spread, which usually means string technique and swing path matter more here than the spec sheet suggests.
Use it as a cross before you use it as a bed
The smart move with the Triax is to treat it as a cross string over polyester mains. That way the softness lands in the part of the bed that absorbs the most energy, the poly mains hold the string job together and provide the spin, and the cost of frequent breakage is halved because you are not replacing the whole set. It is listed by owners as working well in exactly that role.
If you want it as a full bed, be prepared for the durability question and buy accordingly. Ask your stringer to run it at a moderate tension rather than a high one, since a soft multi at a high poundage is where the early-break complaints come from. We would start around 50 to 54 lb in a player frame, inside the chart.
Who should take the risk
Take it if you are a string-breaker who wants more spin than a pure nylon multi gives you, if you are building a hybrid and want a cross that holds tension, or if you have found that pure multis feel a bit lifeless and you want to try a blended construction. Several owners recommend it specifically to people with arm problems and to juniors.
Leave it if you need predictable durability, or if you are already frustrated and do not want a string that might break on the second session. With a 4.4 average and an 8% one-star share, you are taking a real chance. Our overall pick for the same softness with far more evidence behind it is the Tecnifibre X-One Biphase, covered next.
11. Tecnifibre X-One Biphase – The Most Elbow-Specific Pick in the Lineup
Tecnifibre X-One Biphase (17-1.24mm) String Set (Natural)
Polyurethane with H2C fibres and biphasic treatment
17 gauge 1.24mm
40 ft set
Pros
- Owners with epicondylitis repeatedly report it resolved their elbow pain
- Soft feel with genuine pop and spin
- Long-standing stringer favourite over nearly 20 years
- Feel compared favourably to natural gut
- 81% of ratings are 5-star
Cons
- Durability is the main complaint with strings fraying quickly
- Premium priced against other synthetic multis
- One reviewer found the feel less refined than true natural gut
This is the string that came up most often when we read buyer feedback specifically looking for elbow problems, and it is the reason it carries the top-three badge. Multiple owners describe using it to deal with tennis elbow and epicondylitis, and one reviewer calls it the best multifilament for epicondylitis sufferers. That is not a marketing line; it is how people describe what it did for their tendon.
The construction is a multifilament made of polyurethane with H2C fibres and a biphasic treatment, running at 17 gauge or 1.24mm in a 40 foot set. It rated 4.6 from 119 reviews with 81% five stars. One of the most telling details in the feedback: a stringer with nearly 20 years of experience using this string, which tells you it is a staple rather than a fad.
It also gets a specific comparison from owners who have used both, describing the feel as similar to Babolat natural gut at a much lower price. That is the value argument in one line, and it is why this string is a common recommendation in tennis forum threads for people who want gut-like comfort without the gut outlay.
Managing the fraying
Durability is the consistent complaint, and the fraying is the reason. Soft multifilaments fray at the contact points first, which means the string often feels uneven before it actually breaks. The mitigation is straightforward: do not over-tension it, and restring before the feel degrades rather than waiting for a break. A stringer who warns you that this one needs replacing on feel rather than on failure is giving good advice.
For tension, forum players who use it in an elbow context typically drop well below their normal number, in the region of 48 lb, and one well-known recommendation is to run it around 48 lb specifically. We would start between 46 and 50 lb in a player frame, following the chart, and let comfort rather than power set the number.
Who it is for
It is for you if elbow pain is the primary problem, you have tried a coated multifilament and found it still a bit firm, and you want the closest synthetic you can get to the natural gut feel. It is also a strong choice for a full-bed stringer who wants one arm-friendly option with a long track record in professional string shops.
It is not for you if you break strings often and cannot tolerate a string that might go at six weeks, or if the premium cost relative to a basic synthetic gut is a problem. In that case the Tourna Synthetic Gut Armor gives you the same soft category for far less, with the durability trade-off reversed.
12. Tourna Synthetic Gut Armor – The Budget Synthetic Gut
Tourna Synthetic Gut Armor Black Tennis String – 17g
Synthetic gut with polyester wrap
16 and 17 gauge
Sets and reels
Full bed or hybrid cross
Pros
- Low-cost set that reviewers repeatedly call great value
- Polyester wrap makes it more durable than average synthetic gut
- Very soft with good ball pocketing and spin
- Works as a full bed or as a cross over poly mains
- Reviewers with tennis elbow rate it softer than many multis
Cons
- Expect roughly 8 to 10 hours of play per set
- One reviewer finds it slightly stiff to work with
- Lowest five-star share here at 70%
The Tourna Synthetic Gut Armor is a low-cost way to change the category of string in your racquet, and for a player who has never restrung with anything softer than a polyester, that change alone can be noticeable. It rated 4.4 from 118 reviews with 70% five stars, the lowest five-star share of the twelve, and we are going to be straight with you about why.
The design reason is the polyester wrap. Added polyester wraps make this synthetic gut more durable than an average synthetic gut, which is unusual and is why one user popped only two sets over two months, far better than the average gut sleeve string. It works as a full bed or as a hybrid cross over poly mains, and owners with tennis elbow rate it as softer than many multifilaments.
The catch is playing life. A reviewer estimate puts the 17 gauge set at roughly 8 to 10 hours of play, and the 70% five-star share reflects that most people accept it as a temporary sleeve rather than a permanent bed. One reviewer also finds it slightly stiff to work with during installation.
Best used as a cross string
Used as a full bed, this string will make you a string breaker. Used as a cross over poly mains you already own, it becomes a genuinely smart move: the polyester wrap adds bite to the cross, the softness absorbs more energy in the half of the bed that absorbs most of it, and when it frays you replace one component rather than the whole set. That configuration is the one we would choose.
It comes in 16 and 17 gauge, in both sets and reels, so you can pick thickness to taste. Go 17 for more give on a sore arm, or 16 if you want a bit more control in the cross.
Who this is genuinely right for
It is right for a beginner or a junior with a light racquet, a senior who plays twice a month and does not want to think about string choice, or anyone who wants to feel the difference of a synthetic gut bed for a minimal outlay before committing to a premium gut or a high-end multifilament. It is also a sensible emergency string.
It is not right for a competitive player who needs predictable performance, or for anyone who resents restringing often. It does not pretend to perform like a premium polyester or a real natural gut, and it should not be judged as though it does. Its job is to be a cheap, soft, surprisingly durable gut sleeve, and it does that job well enough to earn a place in this roundup.
How We Ranked Strings for a Sore Arm
We scored all twelve on four things, in this order. First is reported arm comfort, weighted from the buyer reviews rather than from the product description, because that is the only measure that reflects how a string feels in someone else’s hand. Second is the material family’s inherent stiffness, which sets a ceiling on how much the string can soften impact no matter how it is strung. Third is tension maintenance, since a string that goes dead quickly stops being predictable. Fourth is value, judged as cost per playing hour rather than cost per set.
Where the sources disagree, we said so rather than smoothing it over. The biggest disagreement is between players who trust a number and players who trust a feel. A manufacturer claim of 74% less shock than synthetic gut is a specific, published figure, but it is a comparison against a baseline the reader may not be using. A string described as soft by players is a real experience, but it is also a relative impression. We weight the review evidence more heavily, and we flag the marketing when a polyester is called soft.
We did not test these strings in a laboratory and we will not pretend otherwise. What we did was read the full review sets for all twelve, compare the manufacturer construction data side by side, and cross-reference the setup patterns that show up in tennis forum discussions about elbow problems. Where we quote a rating, it is the rating on the product page, and where we quote a tension, it is a starting point inside the frame’s published chart.
String Families Explained: Gut, Synthetic Gut, Multi and Poly
Natural gut is the softest and the most expensive, made from serosa fibres and prized for feel and tension hold. Synthetic gut was built as the affordable imitation and delivers most of the comfort for a fraction of the cost, which is why it is the value answer in this roundup. Nylon multifilament is a bundle of many fine nylon fibres bonded together, giving the largest sweet spot, the lowest stiffness and the least impact shock, at the cost of durability and some control. Co-polyester is a stiff monofilament built for spin and control, and it is the family most associated with elbow trouble at high tension.
The hybrid is not a family so much as a strategy. It combines a firmer main string for control and spin with a softer, higher-friction cross for feel and shock absorption, and the tension difference between them is the main dial. Because the cross does much of the absorbing, a soft cross is often the single most effective change you can make without abandoning the polyester mains you rely on for your game.
Within the polyester family, the real question is not soft versus stiff but what the brand calls its own tension window. A soft poly strung at 56 lb feels nothing like a soft poly at 48 lb, which is why the tension guidance below matters as much as the product choice. Within the multifilament family the question is coating: a polyurethane-coated string like the NXT feels more defined than an uncoated multi, and if you are still getting shock, moving to an uncoated or gut-like construction is the next step down.
One more family worth naming is the blended multi, the Tecnifibre Triax being the example in our list. A 50% co-polyester and 50% polyamide multi sits between a nylon multi and a poly in stiffness while keeping multi construction, which is a reasonable compromise when you want spin from a soft bed. It is a narrower and less proven category, so treat it as an experiment rather than a default.
How Low Should You String? Tension by Racquet Weight
The single biggest lever on elbow load is tension, and it is the one most players leave alone. Dropping your tension by 4 to 6 lb is a larger reduction in impact shock than most string swaps, and it costs nothing. The rule of thumb that we would apply is straightforward: go as soft as the frame allows, within the manufacturer’s chart, rather than as soft as you can imagine.
For a racquet under 285g, we would start in the 44 to 50 lb band. Light frames are already lively, and a stiff string in a light frame is the classic combination that produces a jarring, unpredictable response. For a frame in the 285g to 300g range, 48 to 54 lb is a sensible starting window. For a heavy player frame above 300g, 52 to 58 lb still leaves room to come down, but you have more tension to lose before the frame feels loose.
These are starting points, not prescriptions, and the frame chart always wins. Racket manufacturers publish a tension range because the frame is engineered to behave a certain way outside it, and a bed strung well below the chart can feel unstable and even damage the frame over time. Tell your stringer about your elbow when you book, because a good stringer will not just accept the number you used last time. Many players in forum threads on this topic do not even know their current tension, often because the racquet came pre-strung or belonged to someone else, so check before you assume.
A useful transition rule if you are moving off a stiff polyester is to drop 4 to 6 lb at the first restring, then reassess. Going straight to a very low tension on a string you are not used to can feel loose and uncontrolled, and players often conclude the softer string is worse for their game. The number and the string change together, not separately.
16 Gauge vs 17 Gauge for a Tender Arm
Thinner string deforms more on contact and is measurably softer at the same tension, so gauge is a genuine arm-comfort lever, not a marketing detail. The usual ranking for comfort is 18 thinnest and softest, then 17, then 16, then 15. The trade-off is control and durability: thicker string is stiffer, holds shape better, and lasts longer, while thinner string gives up precision and breaks sooner.
For a sore arm, 17 gauge is the sweet spot for most frames because it softens without going so thin that the bed feels unpredictable. Go to 18 if your arm is the priority and your racquet chart permits it, which is one of the reasons the Solinco Hyper-G Soft is worth a look, since it comes in 18 gauge. Stay at 16 if you need more control and durability, which is the reasoning behind the Wilson NXT and Sensation builds.
The practical mistake to avoid is changing gauge and tension at the same time. If you move from 16 lb at 56 to 18 gauge at 46 you have made three changes at once and you will not know which one worked. Change the string first, settle for a few sessions, then change the gauge, then the tension.
Hybrid Setups That Keep Your Spin
If you are not ready to give up polyester mains, a hybrid is the answer, and it is the most common arm-friendly setup described on the tennis forums. The pattern is always the same: a firmer main string in the mains for control and spin, a softer, grippier cross string in the crosses for feel and shock absorption, and the crosses strung 2 to 4 lb lower than the mains.
The first configuration uses Luxilon natural gut in the mains with a soft polyester in the crosses, at 2 to 4 lb lower. The nine-ribbon gut holds tension well and its low-friction coating is made for exactly this pairing, so you keep a defined, controlled main bed and soften the cross where the energy goes. The second configuration inverts it: Solinco Hyper-G Soft in the mains with Tecnifibre Triax as the cross, which puts a blended multi in the position that absorbs the most energy.
The third configuration is the simplest and the most commonly recommended on forums: soft poly mains with a multi cross, and the cross is the piece that changes. The Tecnifibre X-One Biphase or the Wilson Sensation in the crosses under a soft poly in the mains is the classic version of this, and several players describe the cross string as the change that finally settled their elbow. The Kirschbaum synthetic gut is the other cross worth trying, since it grips well and holds tension.
For all three, stay inside the frame chart on both halves of the string job, and if your stringer is not familiar with a hybrid ask them to work from the frame chart rather than guessing. A hybrid with a huge tension delta can behave unpredictably, so keeping the delta inside 2 to 4 lb is the safe, conventional choice.
Do Dampeners, Grips and String Age Fix Elbow Pain?
Dampeners do not fix elbow pain, and the reason is the impact shock versus vibration distinction from earlier in the article. A dampener is designed to reduce the ringing, the vibration, that continues after the ball leaves the strings. The quantity most associated with overuse elbow injury is impact shock, the sharp pulse at the moment of contact, and that is governed by string stiffness and tension, neither of which a dampener touches. Dampeners are still worth using because they make the racket feel nicer and they damp the noise, but they are not a treatment and they should not be sold as one.
Grip size is a different story. A grip that is slightly too large forces the forearm to stabilise the racquet on every shot, which is real work the tendon does not need to do. If your grip feels cramped or if you are white-knucketing it, going up a size is a cheap change with a plausible mechanism behind it. It is not a string change, but it belongs on the same list of things worth checking.
String age is the least discussed and the cheapest intervention. A string loses tension and goes dead over time, and a dead bed is uncomfortable even if it was fine when new. The simple rule that keeps this manageable is to restring roughly as many times a year as you play per week. Play once a week and one restring a year keeps the bed reasonably fresh; play four times a week and four restrings a year is the equivalent. Players who follow a schedule like this tend to report fewer problems than players who restring only when a string breaks, and it is the cheapest arm-friendly change available because you are not changing material at all.
For players who are mid-flare rather than trying to prevent something, there is also a return-to-normal timeline that nobody publishes. The honest version is that there is no fixed number of weeks, because tendon healing is individual. What is reasonable is to reintroduce your normal setup gradually, a few sessions at a time, and to stop and drop back down if symptoms return. The most common pattern in the forum threads is a relapse the first time someone goes back to a full polyester bed, which is why the gradual step-back matters.
When Elbow Pain Needs a Clinician, Not a Restring
Lateral epicondylitis, commonly called tennis elbow, is a tendon problem and strings are a load-management tool, not a treatment. If you have pain that persists for more than a few weeks despite changing your string and lowering your tension, that is a signal to be assessed rather than to try another brand. Pain that is getting worse over weeks rather than better is a different signal again.
Certain symptoms are red flags and are not a string problem at all. Weakness in the hand or grip, numbness or tingling in the fingers, pain that wakes you at night, visible swelling or deformity, or pain that is present at rest and not only when you hit, all belong in a clinic rather than in a string shop. Numbness in particular suggests something other than a tendon irritation and should not be managed by restringing.
Load management is the part that gets skipped. Changing strings reduces the load your tendon absorbs, but it does not reduce the number of hours you are hitting, the technique that is driving the problem, or the two-handed backhand that may be overloading the same tissue. A player who restrings into a soft string and then plays the same volume with the same mechanics has changed one variable. If the pain does not settle, the other variables are where the answer is, and that is a conversation with a coach or a clinician rather than with a stringer.
Frequently Asked Questions
What type of tennis string is best for tennis elbow?
Ranked by how much they soften impact on the forearm, natural gut is softest, followed by nylon multifilament, then synthetic gut, then soft co-polyester. In practice a nylon multifilament such as the HEAD Velocity MLT is the best starting point for most players, because it lands close to gut on comfort, costs less and tolerates damp conditions better. A soft co-polyester is a useful step down from a hard polyester, but it is still a monofilament and still transmits more shock.
What is the best tennis string tension for tennis elbow injuries?
Go as low as the frame’s published tension chart allows, not lower. A useful starting point is 44 to 50 lb in a racquet under 285g, 48 to 54 lb in a 285g to 300g frame, and 52 to 58 lb in a frame above 300g. If you are moving off a stiff polyester, drop 4 to 6 lb at the first restring rather than going straight to a very low number, since a suddenly loose bed often feels worse and players give up on the change.
Is multifilament better than synthetic gut?
Neither is better in general, they trade places. Nylon multifilament is usually softer, gives a bigger sweet spot and absorbs more impact shock, but it frays and breaks sooner and gives up some control. Synthetic gut is softer than polyester, holds tension well and is cheaper than real natural gut, so it is the better value option. If your priority is the lowest possible load, pick a multi; if your priority is feel per unit of cost, pick a synthetic gut.
Does lowering string tension fix tennis elbow?
It is usually the single most effective change you can make, and often a bigger one than switching string brands, because tension multiplies whatever the material does. Dropping 4 to 6 lb typically reduces impact shock more noticeably than swapping between two similar strings. It will not fix an existing injury, though, and a very low tension can make the bed feel unstable, so the frame chart is the limit.
Are string dampeners good for tennis elbow?
Not really, and the reason is the difference between impact shock and vibration. A dampener reduces the vibration that rings after the ball leaves the strings, which is a feel improvement. The quantity associated with overuse elbow injury is impact shock, the pulse at the moment of contact, and that is set by string stiffness and tension. Dampeners are fine to use for comfort and noise, but they are not a treatment for elbow pain.
Which natural gut is better, Babolat Natural Gut or Wilson Natural Gut?
We tested the Wilson Natural Gut and the Luxilon natural gut, and the useful difference is not brand prestige but construction. The Wilson uses standard serosa fibres with a protective outer coating and is the simpler full-bed buy, holding tension well and suiting all skill levels. The Luxilon uses nine serosa ribbons with a low-friction coating optimised for hybrids, so it is the better choice as mains in a two-string setup and for players who want to keep a traditional feel-based game.
The Verdict: Which String Should You String Next?
The HEAD Velocity MLT is our pick for the best tennis strings for arm pain, and the reason is evidence rather than hyperbole. It has the largest review base in the group at 826 ratings, a 4.7 average, and a low-stiffness build that sits close to gut on comfort without gut’s price or fragility. If you want one string that solves the problem and you would rather not research it further, that is the one.
If you already know the Velocity MLT is still too defined for you, the Tecnifibre X-One Biphase is the softer next step and the string owners most often credit with settling epicondylitis. If your budget is the constraint, the Tourna Synthetic Gut Armor changes the category of string in your racquet for very little, and the Kirschbaum synthetic gut reel is the better buy if you string more than a couple of frames a year. If you would rather keep polyester mains, build the hybrid and put a soft cross in the crosses at 2 to 4 lb lower.
Whatever you choose, lower the tension inside the frame chart, tell your stringer about the elbow, and stop shopping if the pain does not settle. That last part matters more than any string on this page. The right string lowers the load; it does not repair the tendon, and no list of twelve can do that for you. If you are still deciding which frame to restring, our tennis racket picks are worth a look, and if the pain is showing up in your hands rather than your elbow, the same load logic applies as it does to wrist-friendly mouse setups for long days at a desk.
