Head Sonic Pro 125/17 String Set squash strings The 1st Grand Slam tournament

The 1st Grand Slam tournament of the year uses this high-performance tennis ball

Wider in the middle to reduce shock and vibration where most balls are hit

The Syntec Pro grip ensures better control of your racket thanks to its sticky feel which enhances traction

The Custom Damp allows players to adjust the dampening effects to fit their personal preferences by choosing to play with or without the capsule containing tiny steel beads

And it's with them in mind that we've developed this absorbent grip allowing you to really feel the handle for extra control
