String Project Armour is the benchmark monofilament tennis string for competitive players.
A revolutionary monofilament in terms of feel and control, it manages to generate excellent spin despite its smooth profile.
With strong snap-back and greater impact consistency, it stands at the top of our competitive range, delivering optimal performance in every aspect.
Armour redefines expectations for a competitive monofilament string. Experience an unprecedented feel and ball control that allow you to direct the game with millimetric precision.
Its superior impact consistency gives you the confidence to push every shot to the limit, knowing exactly where the ball will go.
Do not be misled by its circular profile: String Project Armour is designed to maximize spin.
Thanks to an outstanding snap-back effect (the quick return of the strings to their original position after impact), this string “bites” the ball, producing heavy spin that puts opponents under pressure with arched trajectories and unpredictable bounces.
Play intensely while protecting your arm. Armour is one of the most Arm Friendly tennis strings on the market. Its innovative co-polyester construction, carefully balancing Soft Polyester and High Density Polyester (HDC), absorbs harmful vibrations and guarantees a high level of comfort — ideal for preventing fatigue and injuries — without sacrificing the responsiveness required for a powerful game.
For a competitive player, consistency is key. String Project Armour excels in tension maintenance thanks to a special surface treatment with alpha-olefins and multiple thermal fixing processes. This ensures the string retains its optimal playing characteristics for longer, delivering reliable performance match after match.

Thanks to the pre-stretch of the core, the entire string minimizes the loss of strain and, at the same time, it allows to reduce the stringing tension.
"Heating treatments" remove internal stress and align string’s potential irregularities. Moreover, they make strings more flexible and elastic.
The string is perfected with a wax layer. This treatment extends the duration substantially reducing the wear and making stringing easier.
String’s Friction’s decrease offers: diminished strings’ motion, greater potential spin due to greater snap back and a lasting duration.

Everybody can find the most suitable string at String Project preserving game comfort characteristics and arm protection. Armour is roster’s “toughest” string, the one which is more aimed to ball’s control and, for this reason, addressed to that player who wants to preserve all those brand’s key-characteristics, softness, flexibility, game comfort but focusing on the control of their own moves.
