With the poly ball, rubbers are required to be more powerful. Until recently,
many rubbers were equipped with a hard top sheet supported by a hard sponge,
which were believed to add more power to the rubber, but resulted in instability for some players.
Therefore, today’s trend is to adopt a softer top sheet in order to lessen the instability
But that does not satisfy a certain group of players
who are accustomed to using a hard top sheet + hard sponge rubber.
They still miss the powerful topspin shot, which is only attainable with a hard top sheet + hard sponge composition.
Nexy has accomplished this without losing the integrity of the rubber by developing a new form of column structure under the topsheet’s surface. You will find this rubber well-balanced and consistently predictable.
So, we can continue to enjoy this attractive composition of a very grippy hard topsheet and powerful high tension-bubbled sponge with KARIS M & KARIS M+& H.
KARIS M HARDNESS: 43
KARIS M+ HARDNESS : 47
KARIS H HARDNESS : 50+
