Increased Distance and Soft Feel: Callaway's game-changing Dual SoftFast Core is engineered to promote faster ball speed and distance off the long clubs and more control in the short clubs. Longer Carry from HEX Aerodynamics: Promotes longer carry and distance with a lower, piercing and workable ball flight for a Tour ball. Superior Distance off the Long Clubs and Control off the Short Clubs: The advanced Tri-ionomer mantle design helps to regulate spin for each club. It promotes less spin off the long clubs for distance, and more spin off the short irons and wedges for control into the green. Soft Feel and Increased Greenside Control: An ultra-thin urethane cover combines outstanding greenside control with extraordinary feel. Increased Focus and Visibility: the Truvis pattern is specifically designed to maximize your view of the golf ball for better focus and visibility.
