Featuring several industry firsts, the XTD Driver is made like no other driver in golf. With a redefined manufacturing process, each head is tested four times to ensure the hottest permissible face within USGA rules and the tightest tolerance in golf. Today's current competitive standard is measuring only a small percentage of the total production. XTD is the only driver to feature Cut-Thru Slot™ technology. These create an unmatched spring-like effect and expands the sweet spot to promote maximum ball speed on off-center and on-center shots.
