High Tension
Hight Tension Technology enhances the reaction of the playing surface
by adding tension to the rubber molecule itself this is made possible
by applying special substances to rubber material

Micro Layer
The base of top sheet is very thin, visible to the naked eye. The rubber
compresses and the surface is depressed by the ball on impact thus enabling
a high degree of rotation to be imparted on the ball

Spring Sponge
Like a coil spring, the spring sponge absorbs the incoming energy of the ball
and releases it as additional power for the player’s own shot. Rubbers with
Spring sponge technology enable shots with high amounts of spin

Spring Sponge X
Easier to impact than conventional Spring Sponge and with an improved
rebound the new Spring Sponge X Provides the increased feeling of holding
the ball on the racket and enables to arc the ball even better, creating more
spin and powerful shots, all with a total weight reduced by about three
percent, compare to Spring Sponge with the same hardness and thickness
