Xiom Sigma 3 Rubber

Spin Weapon with Upgraded Speed
Higher success rate with "big window" over the net
Enhanced black Carbo-Sponge to generate more power
Longer lifetime and curability of rubber

Sigma 3 construction aims at speed performance for offensive players on the platform of spin-innovated HYPER ELASTO. Deeper ball-dragging on the surface for spin and fast repulsion from the matching sponge for speed are superbly balanced. Higher ball-trajectory opens the large safe-zone (Big Window) over the net. Enhanced black Carbo-Sponge maximized the internal efficiency to generate additional energy onto the ball. More spin rotations also compensate the speed against air resistance. Resilient tensile structure improves the lifetime of rubber by 30-50%.
