HURRICAN PRO 3 TURBO BLUE uses the topsheet from the iconic DHS Hurricane 3 combined with a new type of Japanese sponge. The resulting combination has produced a version of Hurricane 3 with that familiar tacky topsheet that now has the excellent feel and sensation of a fast and elastic sponge. Compared to the orange sponge version, this blue sponge version is harder and faster. This rubber is produced by Nittaku, so the quality control that they are famous for ensures that you will get a quality sheet every time.
