“Controlled offensive with high tension”

A rubber with high elasticity; it is created by impacting tension into the rubber molecule.

Sponge thickness guide

Each rubber has a lineup of multiple sponge thicknesses. Thinner sponge = lighter weight, lower bounce, suited for defensive play. Thicker sponge = heavier weight, higher bounce, suited for offensive play.
