The special formulation and cell structure enable the NEXTENS sponge to interact more efficiently with the pimples below the surface that is in contact with the ball.
The GT (Great Tension) evolution in our NEXTENS sponge provides additional strenght, as well as transmitting greater rotation onto the ball.
Speed is defined by the specificities of the sponge + topsheet and mostly by the characteristics of the sponge (resilience ‘spring effect’ + thichness + hardness). Thick sponge (2.0mm or max) will be more suitable to OFF/OFF+ players whereas thinner (1.6 or 1.8mm) will offer better control and suit better all-round players. Sponge hardness is generally measured in degrees (higher grade means firmer sponge). Our technologies will bring enhanced “speed” performance.
