If your elbow or shoulder starts complaining after a long rally, the strings may be part of the problem—but they’re rarely the whole story. A stiff polyester setup, high tension, an overly light racquet, and worn-out strings can all add up. The good news: switching to a softer string, or changing only the mains in a hybrid, can make a racquet feel more comfortable without forcing you to give up control entirely.
For most players looking for a gentler setup, multifilament strings and natural gut are the first places to look. They tend to feel more elastic than polyester and absorb more of the sharp impact sensation. “Arm-friendly” is personal, though: your racquet, tension, swing, and string condition all affect how a setup feels.
What makes a tennis string arm-friendly?
Natural gut and multifilament strings are made with many fine fibers, giving them a more forgiving response than typical polyester monofilament strings. Polyester is popular with players who hit hard and rely on spin, but it can feel firm, especially when strung tightly or left in the racquet after it has gone dead.
That doesn’t mean every player should switch to the softest string available. A string that feels comfortable but launches the ball unpredictably can make you grip harder or shorten your swing. The aim is a setup that feels comfortable while still letting you hit freely and confidently.
These five options are useful starting points. Feel varies by racquet and tension, so treat the descriptions as a guide rather than a guarantee.
| String | Type | Good fit for | Trade-off |
|---|---|---|---|
| Babolat VS Touch | Natural gut | Maximum comfort and lively response | High cost; needs care in damp conditions |
| Wilson NXT | Multifilament | Comfort-focused all-court players | Can fray and lose crispness over time |
| Tecnifibre X-One Biphase | Multifilament | Players wanting a lively, powerful feel | Not the longest-lasting choice for frequent string breakers |
| Head Velocity MLT | Multifilament | Comfort at a more accessible price | May feel less plush than premium multifilaments |
| Prince Premier Control | Multifilament | Players seeking a more controlled response | Still wears faster than durable polyester for heavy hitters |
Five strings worth considering
1. Babolat VS Touch: the premium comfort option
Natural gut is often the reference point for a soft, responsive string bed. VS Touch offers strong comfort and a lively feel, with good tension maintenance compared with many other string types. It can suit players who want their racquet to feel plush without feeling dull.
- Pros: Comfortable, elastic feel; useful tension stability; excellent for full beds or hybrids.
- Cons: Usually expensive; can be vulnerable to moisture and wear; not ideal if you frequently break strings.
Gut is also a popular choice in the mains paired with a softer cross string. If you play in wet conditions, ask your stringer about protection and care before choosing it.
2. Wilson NXT: a familiar multifilament feel
NXT is designed to provide a comfortable, lively response without the cost of natural gut. It can work well for recreational players who want to soften a firm racquet or replace a full-bed polyester setup. The feel is generally more forgiving than a stiff co-poly, though no string can guarantee relief from pain.
- Pros: Comfortable impact; easy to use in a full bed; available in multiple gauges.
- Cons: Can fray as it wears; heavy topspin hitters may break it quickly; feel changes as it loses freshness.
3. Tecnifibre X-One Biphase: lively and powerful
X-One Biphase is a premium multifilament known for a lively response. Players who feel that some soft strings are too muted may appreciate its pop and responsiveness. That liveliness can also mean a higher launch or more power than some control-oriented players want, so a sensible tension and a short playtest matter.
- Pros: Comfortable feel; easy depth; responsive at moderate swing speeds.
- Cons: Premium pricing; may be too lively for players who already struggle to control depth.
4. Head Velocity MLT: a practical first experiment
Velocity MLT is a multifilament option worth trying if you want a softer setup without immediately choosing a premium string. It offers a useful balance of comfort, access to power, and control for many club players. If you’re switching from polyester, it can feel noticeably livelier, so consider starting near the middle of the tension range recommended for your racquet rather than making several changes at once.
- Pros: Versatile; often a sensible value; suitable for a full bed or hybrid.
- Cons: Not as plush as some premium options for every player; durability may disappoint frequent breakers.
5. Prince Premier Control: a softer string with a steadier response
Premier Control is a multifilament aimed at players who want comfort but don’t want the springiest possible feel. It can be a reasonable middle ground for someone moving away from polyester and concerned about balls flying long. As with any multifilament, frequent string breakers may need a more durable setup.
- Pros: More measured response than especially lively strings; comfortable alternative to a full bed of polyester.
- Cons: Won’t match polyester’s durability for heavy hitters; the feel may still be too lively for some players.
How to choose and set up a softer string
If you currently use full polyester, switching to a multifilament or natural gut is a clear first test. Keep your racquet and other equipment the same so you can tell what the string change does. If you’re not sure where to start, ask your stringer to stay within the racquet manufacturer’s recommended tension range and discuss a moderate tension rather than automatically stringing at the high end.
A hybrid can preserve some of polyester’s control while making the bed more comfortable. A common approach is a softer multifilament or natural gut in the mains, with a softer-feeling polyester in the crosses. But the poly still influences the response, and a hybrid is not automatically arm-friendly. For persistent discomfort, a full bed of multifilament or gut is a more straightforward trial than keeping polyester in the setup.
String gauge matters too. Thicker strings often last longer, while thinner strings can feel livelier and may break sooner. Don’t assume thinner always means more comfortable: the whole setup determines the feel. Make one change at a time and note the string, gauge, tension, and how your arm feels during and after play.
Don’t overlook the racquet or old strings
String choice is only one part of comfort. Racquet weight, balance, grip size, frame stiffness, technique, and playing load can all matter. A very light racquet or a grip that feels too small or too large may encourage a player to squeeze tightly. If discomfort continues, have a knowledgeable coach or racquet specialist look at the full setup rather than repeatedly changing strings.
Strings also change with use. Polyester can lose its crisp response before it breaks, and a worn string bed may feel harsh or unpredictable. Multifilaments and natural gut can fray or lose playability as well. If a setup used to feel comfortable but no longer does, restringing may be more useful than waiting for a string to snap.
For ongoing or worsening arm pain, take a break and seek advice from a qualified health professional. Equipment adjustments may help, but they are not a diagnosis or treatment.
Frequently Asked Questions
What is the most arm-friendly type of tennis string?
Natural gut and multifilament strings are common choices because they generally feel more elastic and forgiving than polyester. Individual results vary, so a demo or a single restring is the best way to judge your response.
Should I stop using polyester if my arm hurts?
It may be worth testing a full bed of multifilament or natural gut, especially if your polyester is old or strung tightly. If you prefer a hybrid, remember that polyester remains part of the string bed. Persistent pain deserves professional attention.
Does lowering tension make strings more comfortable?
It can make the string bed feel less firm, but it may also increase power or change control. Try a modest adjustment within your racquet’s recommended range, and avoid changing tension, string type, and racquet at the same time.
How often should I restring for comfort?
There isn’t one schedule for everyone. Restring when the strings feel noticeably different, lose dependable control, or become badly worn—not only when they break. Players who hit often may need fresh strings much more regularly than occasional players.
Final Thoughts
For a comfortable starting point, try a full bed of multifilament such as Wilson NXT, Head Velocity MLT, Tecnifibre X-One Biphase, or Prince Premier Control. If you want premium softness and are comfortable with the cost and care, consider natural gut. Keep the rest of your setup steady while you test, and judge the result by both comfort and how freely you can play.
