Donic Bluestorm Series
The Donic Bluestorm Series rubbers feature a thinner topsheet combined with maximum sponge thickness, earning them a reputation as thick-sponge, thin-topsheet rubbers produced in Germany. The series offers a range of sponge hardness, from the softer Z3 variant with excellent control to the Z1 Turbo, which has the hardest sponge and delivers the fastest speed.
