String Project Armour | Monofilament Tennis String

Take your competitive game to the next level with String Project Armour, the benchmark monofilament tennis string for players who demand total performance. It’s not just a string but a precision weapon that combines revolutionary control, effective spin, and exceptional arm comfort. Get ready to dominate every rally with a unique connection to the ball.

Absolute Control and Superior Feel

Armour redefines expectations for a high-performance monofilament string. Experience an unprecedented feel and ball control that allow you to direct the game with pinpoint precision. Its superior impact consistency will give you the confidence to push every shot to the limit, knowing exactly where the ball will go.

Remarkable Spin Generation (Circular Profile)

Don’t be fooled by its circular profile: String Project Armour is designed to maximise spin. Thanks to its exceptional snap-back effect (the rapid return of the strings to their original position after impact), this string “bites” the ball to generate heavy spin that challenges opponents with arcing trajectories and unpredictable bounces.

"ARM Friendly" Technology: Comfort Without Compromise

Play hard while protecting your arm. Armour is one of the most high-performing ARM Friendly tennis strings on the market. Its innovative co-polyester construction, skilfully balancing Soft Polyester and High-Density Polyester (HDC), absorbs harmful vibrations to deliver exceptional comfort—ideal for preventing fatigue and injury—without sacrificing the responsiveness needed for a powerful game.

Excellent Tension Maintenance for Lasting Performance

One of the most crucial qualities for competitive players is consistent performance. String Project Armour excels in tension maintenance thanks to a special alpha-olefin surface treatment and multiple thermal stabilisation processes. This ensures the string retains its optimal playing characteristics for longer, delivering reliable performance match after match.

Advanced Co-Polyester Construction and Circular Profile

Armour’s formula is an advanced blend of co-polyester (Soft Polyester + HDC Polyester) with a circular cross-section. This combination, together with thermal treatments and alpha-olefins, creates a perfect synergy of control, accessible spin, comfort, and lasting performance, placing it at the top of high-performance tennis strings.
