Wilson NXT Duramax 15G Tennis String Natural

The Wilson NXT Duramax 15G is the thickest and most durable version of Wilson’s legendary NXT multifilament line. Designed for players who demand maximum arm comfort but struggle with frequent string breakage, the 15-gauge version provides a massive, stable hitting surface with the highest level of abrasion resistance available in a non-polyester string.

Performance Profile

1. Maximum Gauge Thickness: At 1.32 mm, this 16-gauge string offers a significant increase in material volume compared to standard 16G or 17G strings. This extra mass provides superior durability and a very stable, solid feel against heavy incoming balls.
2. Abscorbex PU Technology: Like the rest of the Duramax (formerly NXT Max) family, this string is infused with Abscorbex polyurethane. This tech helps dampen up to 85% of vibrations, making it one of the most arm-friendly "heavy-duty" strings on the market.
3. Fray Resistance: It features a specialized outer wrap and a higher concentration of Tough High-Tenacity (THT) fibers. This construction is designed to resist the "notching" that typically occurs when strings rub together during heavy topspin exchanges.
4. Consistent Power: While thick, the multifilament construction remains elastic. It provides a generous "trampoline effect," offering easier access to depth than a stiff polyester or a thick synthetic gut.

Best Suited For

1. Heavy-Hitting Multifilament Users: Players who love the feel of NXT but find they snap the 16G version in just a few sessions.
2. Beginners and Intermediates with Arm Pain: An ideal choice for players with tennis elbow who have a larger, more powerful racquet and need a string that won't break under the stress of a large head size.
3. Recreational Players Seeking Longevity: For the club player who wants to go months between restringings without sacrificing the "plush" feel of a high-end multifilament.
4. Open String Patterns: Perfect for racquets with 16x18 or 16x19 patterns, where thinner strings tend to move excessively and snap prematurely.

Pro Tip:

Because the 15G Duramax is quite thick, it will naturally create a tighter, lower-powered string bed. To prevent the racquet from feeling too "stiff" or heavy, consider stringing this 3–5 lbs (1.5–2 kg) lower than your usual 16-gauge multifilament tension.
