XXIO Prime 11 Hybrid Flat Cup Face For off-center strikes with the Driver, Fairway Woods, and Hybrids, the new Flat Cup Face expands the high COR region of each club face, increasing your ball speed and distance. Draw Bias Bulge Design This new face curvature on the Driver, Fairway Woods, and Hybrids is slightly closed at the heel and open near the toe. The resulting gear effect helps produce a desirable right-to-left shot shape-even if the club face is open at impact. Weight Plus Weight Plus is a counterbalancing technology that places weights in the end of each shaft, located behind your hands as you grip the club. That grip weight helps push the club head up through your backswing for a more consistent top of swing position. And as you begin the downswing, the weight brings your hands into position,keeping your arms closer to your body for a squarer face at impact. Cannon Sole The Cannon Sole in XXIO Prime Fairway Woods and Hybrids improves launch and ball speed. Its unique floating sole weight is shaped like a cannon and allows for a larger Cup Face plus a more flexible sole. The result is more distance, especially when hitting shots off the deck. Lightweight Construction The new XXIO Prime SP-1100 Shaft, with TORAYCA T1100G carbon fiber and NANOALLOY resin, is extremely lightweight to help produce more swing speed and distance with its smooth, easy-to-swing profile. The softer tip section also makes it easier to close the club face and strike the ball square.
