Srixon Z-Star Diamond Golf Balls

Srixon Z-Star Diamond Golf Balls

The ultimate blend of distance, iron control, and greenside spin. The Srixon Z-Star Diamond is the most complete performer in the Z-Star family — a premium three-piece urethane ball engineered for skilled golfers who demand long-game distance, consistent iron control, and tour-level stopping power, all from a single ball. Favoured by Brooks Koepka and trusted by Major Champions worldwide, the Z-Star Diamond is built for players who refuse to compromise on any aspect of their game.

What makes the Z-Star Diamond genuinely unique within the Z-Star lineup is its reformulated FastLayer DG 2.0 Core. Specifically tuned to minimise driver spin for maximum distance off the tee, while simultaneously increasing spin on mid and long iron shots, the Diamond sits in a performance category all of its own. This means more penetrating drives, more control and stopping power on approach shots from further out, and the confidence to attack pins from any distance on the course.

The core is soft at its centre and gradually increases in firmness toward its outer edge — Srixon's FastLayer gradient compression design — delivering exceptional feel without sacrificing a yard of ball speed. A specially tuned firmer outer portion helps the ball rebound quickly off the clubface for the high-launch, low-driver-spin flight that skilled players demand from their long game.

Surrounding the core is a thicker, extra-soft premium thermoplastic urethane cover, 0.6mm thick, now produced using Biomass — a durable, plant-derived material requiring fewer carbon emissions to manufacture, without any compromise to feel or performance. The cover is coated with Spin Skin+ with SeRM (Slide-Ring Material) — a micronic layer of specialised urethane featuring flexible molecular bonds that dig deep into wedge and iron grooves at impact. The result is dramatically increased friction, maximising spin for outstanding stopping power, precise short game control, and more consistent distance on every approach.

Completing the package is Srixon's 338 Speed Dimple Pattern — redesigned with deeper dimensions to punch through air for a penetrating launch, then generate lift to maximise glide distance and deliver a stable, true flight in even the toughest wind conditions.
