SKU: Sig4 Category:


For Dynamic Power-Spin Attackers
Designed for professionally trained players
Powered by extra-hard new Carbo-Sponge
Extra spin capability by new construction and additional built-in tension

Extreme power with extra spins in deadly aggression. Grippy topsheet accompanied by very hard Carbo-Sponge and fully built-in speed-glue effect creates amazing power-spin performance. Maybe too hard for non-professionals to exploit the full capacity. SIGMA 4 provides the advantage to well trained players with higher swing speed. SIGMA 4 stretches the ball from opponent’s court very aggressively and low with extra spin. Extra precision and superb consistency from solid construction also benefits high-speed players.
