The new Z-STAR family of golf balls, Srixon's ultra-premium tour offerings, features a newly formulated, extra-thin, premium urethane cover with Biomass. According to Srixon, this cutting-edge cover is a challenge to manufacture but well worth the trouble, as it provides unparalleled spin and stopping power around the greens.

Every Z-STAR Series golf ball is equipped with Srixon's new FastLayer DG Core 2.0. In the Z-STAR DIAMOND, this redesigned core construction, which gradually becomes firmer around its edge, delivers exceptional feel, increased iron spin, and elevated ball speed.

The Z-STAR DIAMOND offers an excellent blend of long-game distance and short-game spin. Additionally, the DIAMOND suits players seeking increased spin, control, and workability with their long and mid irons.
