The HiPPO 380 S and 420 S drivers represent a significant development in metal wood technology. The level of innovation incorporated in these drivers results in performance that is unrivaled in terms of distance, forgiveness and accuracy. These drivers utilize a series of system matched components available in a wide range of options to provide incredible power behind players of all skill levels. Manufactured from 6 4 Titanium for superior strength and lightness, the heads are of a three piece construction allowing for superior internal weight distribution. The 420 S driver offers the same unmatched performance as its 380 S stable mate, but offers a larger effective hitting area making it the most forgiving driver ever to feature in the HiPPO line up. The optimized center of gravity is positioned low in the 380 to promote medium trajectory with added spin for a longer carry. The 420 S features a back weighted center of gravity to get the ball up quickly for higher trajectory drives.
