Yonex EZONE Xi Lite tennis racquet comes in weighing less than EZONE Xi without sacrificing performance. The result of extensive testing, power, control, feel, and comfort are all wrapped in one moderate weighted package. EZONE Xi stands for Extra Isometric which delivers an improved experience with an even more expanded sweet spot designed for forgiveness and powe The Quad Power System remains on the EZONE Xi Lite and takes advantage of variable thickness at the corners of the head for improved stiffness and repulsion. Also located at the corners is the NeoFade material, a dampening polymer that ensures less vibration for comfort. A completely new development, the SD (Shock Dampening) Grid is inserted into the handle and shaft of the frame between the tubes of the frame to limit shock from reaching the hand. Another evolutionary step was to create a new Oval Pressed Shaft (O.P.S.) throat beam that introduces rounder corners for power while the wider face increases stability.
