Volkl V-Cell 6 Tennis Racquet - Fully Strung Racket & Free Dampener - 4 1/4Volkl goes all in on V Cell technology with the new V Cell 6 Tennis Racquet. With this update, V Cell material is embedded throughout the entire head and shaft, for improved feel and playability. V Cell is a revolutionary, highly durable material, which is stronger and fatigues less than standard graphite. The technology works in tandem with VTex, a silicone polymer butt cap, to make the V Cell 6 a more comfortable racquet than the previous version.
