The XXIO 12 driver is perfect for skilled golfers with moderate swing speeds who need lighter components to generate more speed and distance. Extremely forgiving and perfectly balanced, this driver is a distance machine for those golfers. ActivWing StructureActivWing stabilizes the club head by altering aerodynamic forces at work in the first half of the downswing. The airfoil generates lift, guiding the club to its optimal impact angle for maximum speed and distance. Rebound FrameFour alternating layers of stiff and flexible zones enhance the overall COR rating, which means more spring-like performance for explosive speed and distance all across the club face. Flat Cup FaceThe center of the face is thinner and larger to improve speed all across the face, made from an exotic titanium with high strength to support a thinner design and greater speed.
