NEW BLUESTORM RUBBERS FROM DONIC !
A thinner top surface rubber, subjected to high tension, allows space for a thicker sponge - generating extra power and speed. Thickest variation is called max+, because the sponge is even thicker than previous max versions.
Medium pored sponge, hardest and fastest version. Short, wide pimple structure. For hard-line attackers.
Large pored sponge, medium hard, middle fast version. Long, thin pimple structure. For power-allround players.
Large pored sponge, soft version, perfect sound. Long, thin pimple structure. For allround players.
