HARDNESS:42.5degree FD 3 tension technology has evolved, weight reduction of the entire rubber by making the topsheet thinner. To a newly designed seat that produces rotation + speed, we combined soft sponge 0.1 mm thicker than before. A soft sponge of 42.5 degrees is the speed of a large bubble + control version. "Blue Storm Z3" is soft, it fits a player who places emphasis on powerful hitting and stability feeling.
