Hippo's patented Integrated Technology marries ultra light woven carbon fiber side rails to a 6-4 titanium crown and sole that is welded to the super hard SP700 titanium face allowing maximum COR. 6 grams of additonal weight are positioned at the back corners stabalize the club head on miss hits for incredible forgiveness. The aerodynamically shaped 460cc club head is designed to reduce drag on the backswing and generate higher head speed at impact for longer drives. The Hex 2 is powered by the Hippo Propritary CP4 shaft with high modulus graphite fibers
