Multifilament tennis strings: comfort, power and feel
A multifilament tennis string is made of hundreds or even thousands of synthetic micro-fibres (usually nylon) bundled into a single soft, elastic string. It is the closest thing to natural gut: very comfortable, powerful and gentle on the arm, it suits beginners, all-round players and anyone with elbow trouble. Its limit: it wears faster than a polyester monofilament and gives big hitters less control.
Key takeaways
- Definition: thousands of micro-fibres (nylon or other synthetics) wound together, unlike a monofilament made of a single strand.
- Strengths: comfort, vibration absorption, easy power, good tension maintenance.
- Limits: lower durability (fraying), less control and spin for very powerful hitters.
- Monofilament or multifilament? Control, topspin and durability on one side; comfort, power and arm protection on the other.
- Suggested tension: 22 to 25 kg (48 to 55 lb) in most cases.
What is a multifilament tennis string?
A multifilament string is made from hundreds or even thousands of ultra-fine filaments, usually nylon or polyamide, wound and bonded together into a flexible, elastic string. A monofilament, by contrast, is a single solid strand, usually polyester.
Multifilament was designed to mimic natural gut without its price or its sensitivity to moisture. It reproduces much of gut’s appeal: soft feel, power and shock absorption. To compare with the original, read our article on natural gut strings.
What are the benefits of multifilament strings?
Exceptional comfort
Thanks to its soft structure, a multifilament absorbs vibration better at impact: less shock in the arm, less muscle fatigue. It is often recommended for players with tennis elbow or joint pain.
More power
At impact, the strings compress and return much of the energy to the ball: the shot goes deeper without extra effort. A real bonus for players with a fluid swing who are looking for depth.
Good tension maintenance
A multifilament holds its tension longer than a polyester, which relaxes quickly. The feel stays stable for longer and shots are more predictable.
A versatile string
A good balance of comfort, power and control, it suits baseliners as well as players who like to vary pace and spin. It also grips the ball well on touch shots.
Monofilament or multifilament: which should you choose?
The choice depends above all on your game and your arm. Monofilament (polyester) is favoured by competitors and big hitters for its control, spin and durability; however, it loses tension faster and puts more strain on the arm. Multifilament stands out for comfort and power: ideal for an all-round game and for preventing vibration-related injuries.
| Criterion | Multifilament | Monofilament (polyester) |
|---|---|---|
| Construction | Thousands of micro-fibres | A single solid strand |
| Comfort | Very good | Low |
| Power | Very good | Average |
| Control and topspin | Average | Excellent |
| Durability | Average to low | Very good |
| Tension maintenance | Good | Low |
| Who for? | Beginners, all-round players, sensitive arms | Competitors, big hitters, heavy topspin |
In short: if you want power, comfort and arm protection, choose multifilament. If you want control, topspin and durability, and your arm can take it, move to polyester strings. And if you want both, go for a hybrid: polyester mains, multifilament crosses.
What are the limits of multifilament?
- Lower durability: the fine fibres fray and break sooner, especially for players who hit hard with lots of topspin. As a rough guide, a multifilament often lasts 10 to 20 hours of play for a powerful hitter.
- Less control for big hitters: its power can become a drawback when you already hit very hard; these players prefer the firmer feel of polyester.
- Less spin: for a heavy topspin game, a monofilament remains better suited, even if some premium multifilaments offer decent spin.
How to choose a multifilament string
Gauge (thickness)
Thinner gauges (16 or 17, about 1.30 and 1.25 mm) give more touch and feel but are less durable. Thicker gauges (15, about 1.40 mm) last longer at the cost of some feel and power. A 16 gauge is often the right compromise.
Tension
A tension of 22 to 25 kg (48 to 55 lb) suits most players: around 22-24 kg for more power and comfort, up to 25-27 kg for more control at the expense of comfort. See our guide to tennis string tension.
Which models are often cited?
- Tecnifibre X-One Biphase: often cited among the best multifilaments for its balance of comfort, power and control, good tension maintenance and decent spin.
- Wilson NXT: known for its comfort and popular with players with sensitive joints.
- Tecnifibre Multifeel: a comfortable option, often recommended for elbow pain.

- Players with arm pain: tennis elbow, tendinitis, wrist pain. It is the go-to string for playing more comfortably. See also racquets and tennis elbow and, if the pain persists, our sports medical center.
- Players looking for power who want more depth without forcing.
- All-round players who mix heavy hitting with longer rallies.
- Beginners: comfortable and easy to play, it helps you improve without putting your arm at risk.
On a tighter budget, classic nylon strings (synthetic gut) offer some of these qualities for less.
At the Mouratoglou Academy on the French Riviera (Biot, near Nice), many adult campers play with multifilament to protect their arm during intensive weeks. In the Mouratoglou Method, equipment is chosen to fit the player. Discover the Academy.
Frequently asked questions
Are multifilament strings suitable for beginners?
Yes, they are one of the best choices for beginners. Comfortable and powerful, they make hitting easier and reduce the risk of arm pain.
How long do multifilament strings last?
It depends on your style and how often you play. For a hard hitter, they often last 10 to 20 hours of play. A recreational player will usually replace them when they lose tension or start to fray.
Which string should I use for tendinitis or tennis elbow?
A multifilament, or natural gut if your budget allows. Their softness absorbs vibration and limits shock to the joints. Avoid polyester, which is too stiff, and lower the tension slightly.
Can a multifilament be used in a hybrid?
Yes, it is very common: polyester mains for durability and control, multifilament crosses for comfort. It is an excellent compromise for players who break strings often.
Which is better for topspin: mono or multi?
A polyester monofilament, which is better suited to a heavy topspin game. Some premium multifilaments, such as Tecnifibre X-One Biphase, still offer decent spin while preserving comfort.
