A new generation of high viscosity speed type rubber The toughness and elastic balance of the rubber formula, small and medium strength also has a high speed; "new compact sponge" + "high elastic particle penetration technology", 15% more elastic than the traditional sponge. This rubber retains the unique rotation of the hurricane system and the different loop, and significantly increases the speed of the ball, making the power permeability refreshing. Hurricane 8, designed to enhance the loop and speed of 40+ new material table tennis. Style: Fast break + Loop Thickness: 2.15/2.2 (mm) Hardness: 39/40
