Kick X Tour Z Premium Golf Balls (3 Ball Sleeve) THE KICK X TOURZ GOLF BALL IS THE LONGEST PREMIUM BALL IN GOLF - The TourZô will increase your shot distance and improve your play through its precision control. Advanced triple layered construction provides "Tour Soft" feel and the ultimate in scoring performance. Secondly, the Tour Z's main core is constructed using innovative Metal Fuzion Coreô technology to provide maximum C.O.R. - delivering higher ball speeds for explosive distance. METAL FUZION COREô The Metal Fuzion Coreô creates the highest level of coefficient of restitution (COR) or in layman's terms, the highest "spring effect" of any premium ball. This fusion of 3 proprietary metals creates a more concentrated mass in the center of the core. When the ball is compressed it rebounds quicker which gives you faster ball speed off the face. Every 1 mile per hour of ball speed translates into an additional 2.4 yards. The more you compress the Kick Xô ball, the farther it goes! TRIPLE-LAYERED CONSTRUCTION Engineered to deliver soft, tour-like feel and touch around the green.
