The Srixon Z-Star X Golf Ball offers Spin, Trajectory, Acceleration and Responsivesness. The Z-Star X builds on the technology of the Z-Star model and tailors those developments to provide the very best golfers the extra distance and Tour control that they demand. The largest core of any Srixon golf ball, an elastic mid layer to help transfer the power from impact to the core and a thin urethane cover mean the Z-Star X has been designed to increase distance on long shots and to provide ultimate stopping power around the green. Using a firmer cover than the Z-Star allows the Z-Star X to provide the optimal golf ball for players with higher swing speeds. 324 shallow dimples on the cover help promote an aggressive trajectory that will offer optimal distance whatever the weather. The lower trajectory of the Z-Star compared to previous models means that ball speed is consistent throughout the entire shot allowing the Z-Star X to produce more distance from longer carries and extra roll on drives. With fantastic responsiveness the Srixon Z-Star X golf ball offers the golfer wonderful feel making it the best choice for control around the green and for shaping and working full shots.
