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.
