The Drive Z Lite is an expert, ultra lightweight tennis racquet with a competitive spirit. Babolat’s Cortex system features a filter and dampener technology that dampens vibrations for maximum comfort. The grip features the trademarked Woofer technology – the first dynamic system which makes the frame and strings interact when striking the ball. Woofer grips are also credited with absorbing 25% more perspiration. Specifications: Head size: 100 sq. in. Weight: 9.0 oz. (unstrung) Length: 27 in. Composition: Graphite/Zylon Product Review: "Wow!
