The special formulation and cell structure enable the NEXTENS sponge to interact more efficiently with the pimples below the surface in contact with the ball.

The GT (GREAT TENSION) evolution of our NEXTENS sponge provides additional strength, as well as transmitting greater rotation onto the ball.


Speed is determined by both the sponge + topsheet but mostly the specification of the sponge (resilience ‘spring effect’ + thickness + hardness).

A thick sponge (2.0mm or max) best suits OFF/OFF+ players whereas thinner (1.6 or 1.8mm) will offer more control and be more suited to all-round players. Sponge hardness is generally measured in degrees (higher grade = firmer sponge). Our technologies will bring enhanced “speed” performance.
