FEATURES: i-FLEX FACEThis completely redesigned face thickness pattern produces more efficient energy transfer at impact. The added strength of the interior i-FLEX face structure allows the centre of the face to be thinner than last generation, increasing ball speed. REBOUND FRAMEReboundFrame is an entirely unique system that amplifies energy transfer at impact. By utilising two flex zones instead of just one, Rebound Frame maximises flex across the face to increase power, ball speed, and, ultimately, shot distance. LASER FACE MILLINGBrand new for ZXi Drivers, visible Laser Face Milling has been added to the surface to help stabilize spin and add forgiveness in wet conditions. ADJUSTABILITYVarious weight port locations across the ZXi Driver lineup allow you to adjust the flight path or spin to fit your game. And an all-new, 1.5-degree hosel sleeve lets you fine-tune Driver loft, lie, and face angle. STAR FRAME CROWNComplex latticework creates the structural integrity necessary to support an ultralight, remarkably thin titanium crown, ultimately allowing discretionary mass to be set where it best suits each ZXi Driver’s ideal launch and spin characteristics.
