{"product_id":"srixon-z-star-diamond-golf-balls-yellow-2025","title":"Srixon Z-Star Diamond Golf Balls  - 1 Dozen (Yellow)","description":"\u003cp\u003eThe 2025 Srixon Z-Star Diamond in Tour Yellow brings the outstanding all-round performance of the Diamond to a high-visibility finish - and for the first time in the ball's history, yellow is available as a factory option. The colour is dyed directly through the urethane cover rather than applied as a surface coating, meaning it cannot be scuffed white and stays vivid throughout the round. The Z-Star Diamond is the standout performer of the entire Z-Star family - trusted by Brooks Koepka, Keegan Bradley and 2025 US Open champion J.J. Spaun - delivering the ideal blend of low driver spin for distance, strong iron control and exceptional greenside stopping power. In independent testing, the Diamond generated over 6,100 rpm backspin on a 40-yard pitch shot, making it one of the highest-spinning Tour balls available anywhere on the market.\u003c\/p\u003e\n\n\u003cp\u003eThe FastLayer DG Core 2.0 features a unique formulation that starts soft at the centre and firms progressively outward, tuned specifically to minimise driver spin for carry distance while maximising spin with irons and wedges. Srixon's Spin Skin+ coating adds a friction-enhancing urethane layer over the biomass cover for exceptional groove engagement on short game shots, and the 338 Speed Dimple Pattern produces a penetrating, wind-resistant ball flight from the tee. At compression 100, the Diamond strikes the perfect balance between the softer Z-Star and the firmer XV - offering a feel that is soft yet responsive, and a performance profile that suits a wide range of skilled players. Now available in Tour Yellow for the first time, with no compromise to the performance inside. Sold as a dozen.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTour Yellow - First Time Available\u003c\/strong\u003e - Colour dyed through the urethane cover so it cannot scuff white, stays vivid all round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastLayer DG Core 2.0\u003c\/strong\u003e - Minimises driver spin for distance while unlocking exceptional iron and wedge spin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompression 100\u003c\/strong\u003e - Balanced feel and performance between Z-Star and Z-Star XV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElite Greenside Spin\u003c\/strong\u003e - Over 6,100 rpm on short game shots in independent testing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpin Skin+ Coating\u003c\/strong\u003e - Friction-boosting urethane layer for superior stopping power around the green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBiomass Urethane Cover\u003c\/strong\u003e - Extra-thin, plant-derived cover for Tour-calibre feel and improved durability\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e338 Speed Dimple Pattern\u003c\/strong\u003e - Penetrating, consistent ball flight with strong wind resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTour Proven\u003c\/strong\u003e - Trusted by Brooks Koepka, Keegan Bradley and 2025 US Open champion J.J.
