All the great features of the original Rhyzm with a softer sponge. Rhyzm 375 shares the same top sheet as Rhyzm but gives you a sponge with a hardness of 37.5 degrees. The ball contact time, extended by the soft sponge, provides precise ball response and highest control values in all playing situations. Especially when blocking, in counter duels or in return of service, the enhanced ball control is noticeable.
