BLUE STORM Z1

HARDNESS:47.5 degree
FD 3 tension technology has evolved, weight reduction of the entire rubber by making the topsheet thinner. To a newly designed seat that produces strong rotation, we combined a powerful sponge 0.1 mm thicker than before. Small bubble speed type sponge that matches strongly rotating sheet demonstrates high elasticity. Rubber which can hit the most powerful strong rotation drive in "Blue Storm" series, it is "Blue Storm Z1".
