SPINE, BITE AND SPEED: Made with an extra thin, urethane cover that provides tour level stopping power around the greens, the Z-STAR Series gives players more bite for more spin. Paired with the new Spin Skin+ to increase the cover's degree of friction to enhance approach shots and greenside spin on every shot, Srixon claims this new generation will offer unmatched performance and feel. FEELING AND SPEED: Inside the Z-STAR Series is the new FastLayer DG Core, which is soft at the centre and gets firmer from the inside out. The design of this core is intended to maintain a satisfying feel, while also providing ball speed. FLY WELL IN ANY CONDITIONS : Each Z-STAR Series ball features Speed Dimple, the 338 aerodynamic dimples improving overall launch even when wind conditions aren't ideal. Its deep dimensions create a low drag coefficient that helps the ball stay on target and maintain distance, while keeping a penetrating ball flight in headwinds. CONTROL AND CONFORT: The Z-STAR XV's unique core achieves a soft centre that increases dramatically in hardness with an evenly distributed hard outer edge, which boosts ball speed for increased distance and enhances iron spin PREMIUM: Performance, distance, speed, feel, control, aerodynamics: everything is combined to make it a top of the range golf ball to help you improve your game and push your limits!
