Tennis strings 4ST

A real surprise when it hit the market, the grey string 4ST remains a reference in terms of comfort and power. The string is a copolymer with a pentagonal profile and a textured surface, allowing for plenty of spin on the ball. There's now a "Lemon Yellow" version that adds a bit more zest to the string...

This string provides a soft yet incredibly effective strike that helps establish rhythm during rallies. The unique gauge of 1.25 mm is an excellent compromise between power and control.

A careful installation of the 4ST is highly recommended to maintain good tension throughout the lifespan of this string.
