The limited-edition Z-STAR ♦ DIAMOND Keegan Bradley Signature Series Ball honors Srixon’s own 2025 U.S. Captain with a custom take on the ball he plays on tour—featuring an illustrated logo stamp and distinctive packaging.
With a blend of greenside control and long-game distance, the new Z-STAR ♦ DIAMOND also delivers the unique benefit of increased spin on long and mid Iron shots.
WHETHER CHASING MAJOR CHAMPIONSHIPS OR YOUR NEXT PERSONAL BEST, THE ALL-NEW Z-STAR SERIES IS THE CHOICE FOR SERIOUS PLAYERS EVERYWHERE. FEATURING REFORMULATED CORES AND COVERS ACROSS THE LINE, THIS GENERATION OF Z-STAR GOLF BALLS PACKS STRONGER DISTANCE, MORE OPTIMIZED SPIN, AND TOUR-LEVEL STOPPING POWER AROUND THE GREEN. IT'S A FORMULA DESIGNED TO HELP GIVE YOU ONE THING: PURE PERFORMANCE WHEN IT MATTERS MOST.
Every Z-STAR Series golf ball features an extra thin, premium urethane cover for tour-caliber greenside spin, feel and control. Our latest covers are also made with Biomass—a durable, plant-derived material requiring fewer carbon emissions to manufacture. It's our signature unbeatable performance and feel, plus a step toward reducing environmental impact.
For even more spin and control, we add Spin Skin+ coating. This thin layer of specialized urethane increases the cover's friction to enhance your approach shot and greenside spin. New for this generation, the urethane paint used in Spin Skin+ is slightly stronger for more resistance to dirt and grime.
A newly formulated core starts soft in the center and gradually becomes firm around its edge, giving high-speed players exceptional feel, optimized Iron spin, and plenty of ball speed for maximum distance.
Less drag and more lift boosts overall distance and flies straight, even in the toughest wind conditions.
