Tour-Tested Performance With The 2025 Version Of The Srixon Z-STAR, Z-STAR ◆ DIAMOND, & Z-STAR XV Golf Balls

By Dr. Barry Lotz

Who It’s For:

Z-STAR: Golfers who prioritize greenside spin and soft feel.

Z-STAR ◆ DIAMOND: Those seeking a balance of spin and distance.

Z-STAR XV: Players who demand maximum ball speed and distance.

What Sets the Srixon Z-STAR Series Apart?

The Srixon Z-STAR Series lineup has earned its place in the bags of elite Tour players under the Dunlop Sports America umbrella. Players like Shane Lowry (2019 British Open), Hideki Matsuyama (2021 Masters), and Brooks Koepka (2023 PGA Championship) trust Srixon golf balls for their major victories. Most recently, Keegan Bradley, the 2025 Ryder Cup captain, won the BMW Championship with a Z-STAR ◆ DIAMOND ball.

In 2025, Srixon has elevated the Z-STAR Series to new heights with innovative updates tailored to meet every golfer’s needs, from Tour pros to aspiring amateurs.

2025 Updates & Technology

FastLayer DG Core 2.0: A progressive core design starts soft at the center and firms up toward the perimeter, ensuring faster energy transfer and explosive ball speeds for longer drives.

Spin Skin+ Coating: Enhanced for durability, this coating increases friction on short irons and wedges, delivering unmatched greenside spin for better control and stopping power.

Biomass Integration: A new, environmentally friendly material in the cover reduces the environmental impact while maintaining peak performance.

338 Speed Dimple Pattern: Optimized aerodynamics for consistent flight in all conditions.

Tailored for Every Player

While all Z-STAR Series balls share these advanced technologies, they’ve been fine-tuned for distinct performance characteristics:

Z-STAR: With its 88 compressions, this ball offers the softest feel and is perfect for golfers who demand greenside control. It flies lower and spins less off the driver, making it ideal for controlled precise shots.

Z-STAR DIAMOND: The versatile option with 100 compression. It blends greenside spin and higher launch with optimal distance. The Z-STAR ◆ DIAMOND is trusted by Tour pros who want the best of both worlds.

Z-STAR XV: Featuring the firmest feel (102 compression), the XV delivers the longest distance in the lineup. Its low spin with woods and irons, combined with high launch, ensures maximum yardage without compromising peak height.

All ball models are available in Pure White and Tour Yellow for $49.99 per dozen.


Srixon Z-STAR Series DIVIDE: Standout Looks, Serious Performance

The Z-STAR Series DIVIDE (92 compression) is engineered to perform like a Tour-level ball while delivering a unique aesthetic. Its two-tone, premium urethane cover is designed to enhance putting alignment with 360˚ visual guidance and showcase spin with a strobe effect on wedge shots. It comes with the same Tour-caliber feel, speed, and distance you get in every Z-STAR and Z-STAR XV.

NEW FastLayer DG Core 2.0 – A newly formulated core starts softly in the center and gradually becomes firm around its edge, giving high-speed players exceptional feel and maximum approach shot spin.

Z-STAR DIVIDE – provides maximum greenside spin for unmatched control and stopping power. Its premium 3-piece construction gives skilled players complete tour performance, tee to green.

Z-STAR XV DIVIDE – provides maximum ball speed for unmatched Driver and Iron distance. Its premium 3-piece construction gives skilled players complete tour performance, tee to green.

Our testing group was absolutely “blown away’ with each model of the ball based on their current ball choice.
