The Joola Hyperion CAS 13.5 has a strategic layering process that combines multiple materials to deliver exceptional control and feel. CAS technology utilizes a multi-step sandblast abrasive process, creating a unique and texturized surface to increase the spin. The 0.531-inch response polypropylene core provides reduced vibration and increases the power. Sure-Grip technology delivers a pierced anti-slip handle and decreases the handle’s surface dampness for a better grip and impact absorption.
