The new EZONE brings a more vibrant energy to the series with vivid colors and asymmetrical patterns. With the advice from fellow athletes, Casper Ruud, Ben Shelton and Tokito Oda, we've tailored the design to be both energetic and refined. FEATURES: BIGGEST SWEET SPOT IN EZONE HISTORY : Expanding the frame's top length creates a bigger sweet spot. The new changes in the frame structure allow players to experience explosive power while minimizing mis-hits EXTENDED FRAME'S TOP LENGTH : Widening the beam width at the top of the frame enhances responsiveness and power. Resulting in a 4.8% increase in power & responsiveness over the previous model INVERTED FRAME STRUCTURE : Extending a tapered inner frame improves flex to the racquet upon impact and ball pocketing by 6.0% over the previous model
