The Srixon Z-Star Diamond 3 is the ultimate high-performance golf ball, engineered to deliver tour-level distance, spin, and control. At the heart of the Z-Star Diamond 3 is the new FastLayer DG Core 2.0 – a reformulated core that starts soft in the center and gradually firms up around the edges. This innovative design unlocks exceptional feel, optimized iron spin, and blistering ball speed for maximum distance. Meanwhile, the premium urethane cover features Srixon’s Biomass technology, reducing carbon emissions in manufacturing while maintaining the tour-quality performance you expect.
