i-FLEX FACE This completely redesigned face thickness pattern produces more efficient energy transfer at impact, increasing ball speed. DYNAMIC CENTER OF GRAVITY In the both the all-new 3+W and 3W, the Center of Gravity (CG) is placed low and shallow for enhanced distance. Whereas in the higher lofted 5W and 7W, the CG is set differently to enhance spin for increased control. REBOUND FRAME Rebound Frame is an entirely unique system that amplifies energy transfer at impact. By utilizing two flex zones, instead of just one, Rebound Frame maximizes flex across the face to increase power, ball speed, and, ultimately, shot distance. REFINED TOUR SHAPING Progressive new footprints for ZXi Fairway Woods feature leading edge shape changes for a flatter, more grounded look on the toe side; stepless crowns (on most models) for deeper mass positioning within each clubhead; and an improved sole shape for increased forgiveness. ADJUSTABLE HOSEL An all-new, 1.5-degree hosel sleeve lets you fine tune every ZXi Fairway Wood’s loft, lie, and face angle.
