1 Dozen Callaway Tour (IZ)
The Tour I(Z) is the most technologically advanced golf ball on tour. Through 2nd Generation Dual Core Construction, Callaway engineers have designed a tour ball that delivers faster ball speeds. The refined HEX Aerodynamics pattern has been improved to add even more distance. This patented design breakthrough reduces drag and adds flight stability through every kind of wind condition, minimizing the wind's effect on ball trajectory. The new urethane cover uses a proprietary blend to provide Tour-level feel and control around the green with significantly improved durability. It's also available in higher player numbers.
