The new FastLayer DG core is soft in the middle and gradually becomes harder towards the cover, providing the perfect balance between power and control. The result is higher ball speed and longer shots with the driver, while the spin is kept down at long shots for maximum distance. In addition, the ball is equipped with the advanced Spin Skin coating, developed to generate maximum spin at the green without compromising on the soft feel – perfect for short game play with precision. This ball is a favourite among tour players and is used by stars such as Brooks Koepka and Keegan Bradley, which testifies to its high quality and reliability. With Srixon Z-Star Diamond, you get a golf ball that meets the highest demands – both on the tour and in your own game.
