Compared to a conventional round frame, a square-shaped ISOMETRIC™ racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings .

The Oval Pressed Shaft is designed to give players more spin, control, and feel. The shaft flexes at impact, increasing dwell time and minimizing vibrations .  \nR E V O L U T I O N A R Y G R A P H I T E  \nStaying true to our roots, our graphite is sourced and engineered in Japan, giving our research and development team the opportunity to utilize a wide range of materials that suits players of all levels .  \nAggressive, attacking spin is achieved through a carbon nanotube (CNT) structure that binds the graphite fibers together, which reduces energy loss . Due to its resilient properties, the material flexes and provides quick snapback.  \nNamd is technology developed by Nitta Co . , [Ltd. to](Ltd. to)[ ](Ltd. to)uniformly disperse carbon nanotubes in carbon fiber composites .  \nA high strength, high modulus graphite achieves the rare combination of frame stability and flex through its unique properties .  \nTORAYCA® M40X is a next-generation carbon fiber developed by Toray Industries, Inc .  \nV I B R A T I O N D A M P E N I N G M E S H  \nFirst used in our snowboards to reduce vibrations at impact, Vibration Dampening Mesh (V DM) is now used in four of our racquet series .
