OptiFit Hosel adjusts the face angle in Open, Square or Closed positions at address to improve accuracy and trajectory. OptiFit Weights (12 grams and 2 grams) shift the clubhead?s center of gravity to promote either Draw or Neutral ball flights * Revolutionary material in the crown that?s lighter, stronger than titanium. Contains over 7 million turbostratic carbon fibers that allows our engineers to precisely control thickness, resulting in an optimum center of gravity and high MOI. * A combination of VFT® and Hyperbolic Face? Technology creates a large sweet spot and high ball speeds across the titanium face for long, consistent distance. Saves weight that can be redistributed to the perimeter of the clubhead for a high MOI. * Streamlined Surface Technology Aerodynamic contours reduce energy loss from drag during the downswing by 14% compared to the RAZR Hawk® Driver Creates higher impact speeds for added distance
