Quad Power System: Stiffer frame sections at the 4 corners of the framer and vibration absorbing materials inserted resulting in a frame that generates more power. By combining the Quad Power System with YONEX's unique ISOMETRIC head design, Ezone provides and exceptionally stable frame and enlarged sweetspot - creating an 'Explosive Zone' in the string bed that enhances your natural power. Ezone's powerful and precise feel delivers unique performance and explosive power with every shot.

NeoFade® Vibration Absorbing Technology: As part of the Quad Power System, NeoFade® - a material which absorbs impact shock and reduces vibration - is inserted into all four corners of the racquet. Disruptive vibrations within the racquet head are then reduced by 15%.

SD GRID: This newly developed technology utilizes an SD (Shock Dampening) GRID sheet that is inserted into the shaft of the racquet to absorb vibrations created between the two tubes within the grip—adding even more power to your shots. O.P.S.: The improved O.P.S. (Oval Pressed Shaft) manufacturing technology introduces rounder shaft corners that provide a more ideal level of flex. A wider shaft face increases stability—resulting in extended ball dwell time for optimized ball spin and directional control.

X-Fullerene: The revolutionary material X-Fullerene is also inserted into the upper sides of the frame in all EZONE racquets. The cross-linking structure of X-Fullerene improves the internal strength of the frame for superior stiffness and greater power.
