Choosing a tennis string can change how your racquet feels almost as much as choosing the frame. A multifilament string is a popular option for players who want a softer response, comfortable impact and easy power—especially if a stiff polyester setup leaves their arm feeling sore.
This tennis string multifilament guide explains how these strings play, who they suit and how to choose a gauge and tension. It also compares several well-known multifilament strings, from comfortable all-rounders to options with a firmer, more controlled feel.
What Is a Multifilament Tennis String?
A multifilament string is made by bundling many fine fibers together, often with a resin or coating to hold them in place. That construction is designed to feel softer and more elastic than a single solid-core synthetic gut string. It can also offer more comfort than most polyester strings.
Multifilament strings are often made with nylon fibers, though some use other materials or blends. Natural gut is also made from many fibers, but it is a different string type with distinct materials and performance traits.
How Multifilament Strings Play
- Comfort: Their softer response can make off-center hits feel less harsh. This can be helpful for players with arm sensitivity, though no string can guarantee injury prevention.
- Power: Many multifilaments stretch and rebound readily, helping the ball leave the strings with less effort.
- Feel: They often provide a lively, cushioned response that suits touch shots, volleys and long rallies.
- Spin: They can produce plenty of spin with good technique, but usually do not snap back as freely as a slick polyester string.
- Durability: Frequent, hard hitters may break them sooner than polyester. Some players also notice fraying before the string finally snaps.
For example, a recreational player who hits with moderate topspin may enjoy the comfort and depth of a multifilament without needing to swing at full power. A heavy topspin player who breaks strings every few sessions may prefer polyester, or a hybrid setup that combines polyester mains with multifilament crosses.
Six Multifilament Strings to Consider
These options cover different priorities. Feel is personal, so treat the descriptions as a starting point rather than a promise that one string will suit every racquet and player.
| String | Best suited to | General feel | Main trade-off |
|---|---|---|---|
| Tecnifibre X-One Biphase | Players seeking a lively, premium-feeling multi | Soft and powerful | Can fray or break quickly for hard hitters |
| Tecnifibre NRG2 | Comfort and easy depth | Elastic and lively | Less suited to frequent string breakers |
| Wilson NXT | Comfort-focused all-round play | Cushioned and forgiving | Not the longest-lasting choice |
| Head Velocity MLT | Players wanting value and a firmer response | Controlled for a multifilament | Less plush than some premium multis |
| Yonex Rexis Comfort | Players who value a soft, smooth response | Comfortable and easy to play | May lack the crisp control some players want |
| Prince Premier Control | Players looking for a more controlled multi | Firmer and less springy | Not as soft-feeling as comfort-first options |
Tecnifibre X-One Biphase
X-One Biphase is a strong choice if you want a lively response with a soft feel. It can make a demanding racquet feel more forgiving and help generate depth without a huge swing. The downside is typical of many comfort-oriented multifilaments: players who hit hard or play often may wear through it quickly.
Tecnifibre NRG2
NRG2 offers easy power and a comfortable, elastic response. It can suit players moving away from polyester or anyone who wants help getting the ball through the court. If your shots already fly long, or you break strings often, consider a firmer option or a slightly higher tension.
Wilson NXT
Wilson NXT is a familiar all-round multifilament with a notably cushioned feel. It is worth considering for club players who want comfort across groundstrokes, serves and volleys. Its softness is part of the appeal, but it is not designed to match polyester’s lifespan for heavy hitters.
Head Velocity MLT
Velocity MLT is a practical option for players who want a multifilament without an overly springy feel. Its coating is designed to help the strings move, and many players find it offers a useful balance of comfort, control and value. It may feel less plush than premium comfort-focused strings, so test it if softness is your top priority.
Yonex Rexis Comfort and Prince Premier Control
Rexis Comfort is a good one to try if you want a soft response for everyday play. Prince Premier Control takes a different route, aiming for a firmer, more controlled feel than many lively multis. Both can be useful alternatives when a standard comfort string feels too powerful or too soft—but the result depends on your racquet and tension.
How to Choose Gauge and Tension
Gauge refers to string thickness. A thinner string can feel livelier and may offer more bite, but it usually wears faster. A thicker gauge can last longer and may feel a little firmer. Gauge numbers are not perfectly standardized between brands, so check the millimeter measurement when comparing strings.
Tension affects the response too. Lower tension often gives a softer feel and more power, while higher tension can make the string bed feel firmer and more controlled. These are general tendencies, not strict rules. Racquet stiffness, head size, string pattern and your swing all matter.
- If your multifilament feels too powerful, try increasing tension slightly or choosing a firmer model.
- If the string bed feels harsh, try a modest tension reduction or a softer multifilament.
- If strings break too soon, test a thicker gauge or a hybrid before making a big tension change.
Change one thing at a time and note the string, gauge, tension and how it felt. That makes it easier to tell whether an adjustment actually helped.
Should You Use Multifilament in a Hybrid?
A hybrid combines two string types in one racquet. A common setup uses polyester in the mains and multifilament in the crosses. It can add comfort to a polyester bed while keeping some of the control and spin response that the player likes. The feel depends on which string is in the mains, so changing their positions can change the result.
Another option is multifilament mains with polyester crosses. This can feel softer than a full polyester setup, but the polyester still affects the string bed, and the multifilament may wear against it. Players with arm pain should be cautious about assuming any hybrid is automatically comfortable. A full bed of multifilament is often the simpler place to start.
Frequently Asked Questions
Is multifilament better than polyester?
Neither is best for everyone. Multifilament usually prioritizes comfort and easy power, while polyester often suits players seeking control and spin with a full, fast swing. Your playing style, comfort and string-breaking habits should guide the choice.
How often should I replace multifilament strings?
Replace them when they break, become badly frayed or lose their playing feel. Some players restring based on hours of play, but there is no single schedule that fits everyone. If the ball response becomes unpredictable, a fresh set may help.
Can beginners use multifilament strings?
Yes. Many beginners and intermediate players appreciate the comfort and easy power. A multifilament can also be a sensible alternative to a stiff polyester string, particularly if you do not need polyester’s extra durability or control.
What tension should I use for multifilament?
Start with the racquet maker’s recommended tension range and adjust in small steps. If you are unsure, ask a stringer to match your current setup or suggest a middle-of-the-range tension for a first test.
Final Thoughts
Multifilament strings are worth considering if you want a softer, more forgiving racquet response, especially when polyester feels too firm or your arm needs a break from a stiff setup. X-One Biphase, NRG2, Wilson NXT, Head Velocity MLT, Yonex Rexis Comfort and Prince Premier Control offer different takes on comfort, power and control.
Start with the quality you value most, then test one change at a time. The right multifilament is the one that lets you swing confidently, enjoy the feel and keep the ball on your intended target.
