Engineered for golfers who demand maximum performance. The Srixon Z-STAR XV golf ball delivers unmatched technology with incredible feel so golfers can elevate all aspects of their game to score better. The Z-Star XV features a third generation spin skin and speed dimple pattern. The Dual Energetic Gradient Growth Core features a larger, softer inner core and a more consistent outer core in terms of hardness, with the result being faster ball speeds, higher launch angles, and less spin off the tee. Additionally, the 338 Speed Dimple Pattern has been made more aerodynamic to reduce drag, which produces more control and consistent flight conditions. The proprietary Spin Skin coating is also softer in the ball for enhanced feel on all shots and more spin around the greens.
