What we say...

Srixon reveal Z-Star  Diamond Golf ball, a blend of their best-selling premium models and the ball being played by four-time Major champion Brooks Koepka.

Working with their tour stars, including Koepka, Masters champion Hideki Matsuyama and 2019 Open Champion Shane Lowry, Srixon have expanded their superb Z-Star golf ball family to three models with the introduction of the new Diamond.

Designed to blend greenside control and long-game distance, the new ball also delivers increased spin on long and mid-iron shots.

Aimed at better players with high ball speeds, the three-piece Diamond is the idea model for golfers looking to hold the green from anywhere on the course.

Srixon’s FastLayer Core, which is soft at its center and firm around its outer edge, is at the foundation of the Diamond ball, providing speed and feel. It combines with the brand’s proprietary Spin Skin with SeRM – a durable 0.6mm urethane coating that digs deep into wedge and iron grooves on every impact to increase friction and maximise spin and control.

The 338 dimple pattern is designed to deliver less drag and more lift for a long and true flight, even in strong winds 

Brooks Koepka, four-time Major champion and former World No.1, signed for Srixon late last year and has already put the new model into play.

What Srixon say about the new ball

“By working closely with our global Tour staff, we created the Z-Star Diamond ball as an enhancement to our premium Tour line-up,” said Lionel Caron, Chief Sales and Marketing at Srixon Sports Europe.

“It is something of a best-of-both-worlds type product, blending many of the benefits of our two current models. Like the Z-Star XV, the Z-Star Diamond produces really good ball speed and distance. But thanks to a slightly thicker cover, the Diamond features exceptional spin and control on approach shots.

“This is also the ball that our latest signing and four-time Major Champion, Brooks Koepka is using on tour.”

All three of the premium golf balls are aimed at better players seeking either maximum spin (Z-Star) or maximum distance (Z-Star XV) or a blend of the two (Z-Star Diamond).
