Srixon reveal new Z-Star and Z-Star XV golf balls

The new SRIXON Z-STAR and SRIXON Z-STAR XV are the first golf balls in the world to use the macromolecule material (SeRM®), for more spin and soft feel.

Srixon’s sixth generation Z-Star and Z-Star XV golf balls feature a brand new FastLayer core and unique macromolecule blended Spin Skin with SeRM® coating to improve speed, distance, spin and feel. 

According to Srixon, their latest technologies combine for two golf balls which significantly increase spin for short game without sacrificing distance off the tee. 

The FastLayer Core is soft in the middle and becomes increasingly harder towards the outside in order to improve launch and generate faster ball speeds.

The newest feature is an updated ‘Spin Skin’ which combines with their new micromolecule Slide-Ring Material to create a softer cover which Srixon say both dramatically increases distance while maintaining ‘exceptional spin and a soft feel at a high level’. According to the brand, the key benefis of SeRM® are outstanding shape restoration, damage resistance, impact resistance, and vibration absorption.

“Spin Skin with SeRM®” achieves both spin and a soft feel at a high level Srixon has developed golf balls that are the first and only in the world to use SeRM® for the coating (“spin skin with SeRM®”), dramatically increasing distance while simultaneously achieving exceptional spin and a soft feel at a high level.

What is the Macromolecule Material “SeRM®”?

SeRM® is a macromolecule material developed at the University of Tokyo. Macromolecule materials generally have mesh-shaped network constructions with string-like molecules, and those molecules break under stress.

SeRM®, on the other hand, is difficult to break even under high stress thanks to its freely movable connecting parts (cross-links) in the mesh network, and is excellent in shape restoration, damage resistance, impact resistance, and vibration absorption. 

Srixon Z-Star & Z-Star XV Golf Balls: Key Features

1. More spin in short game
“Spin skin with SeRM®” coating has 70% more softness and increases the friction coefficient by 14.4% with its viscosity and elongation properties. This new coating digs deep into the grooves of wedges and irons, enhancing spin and control.

2. Soft feel
The combination of the highly durable ultra-thin super-soft 0.5 mm urethane cover and spin skin with SeRM® that provides excellent vibration absorption and realizes a comfortable soft feel.

3. Scratch-resistant and stain-resistant
Spin skin SeRM® delivers superior shape restoration and damage resistance, making the new SRIXON Z-STAR golf balls resistant to minor scratches caused by sand and pebbles in bunkers, and as a result is stain-resistant.

Better feeling, more spin and extra distance with drivers
The SRIXON Z-STAR’s new core construction delivers high-resilience with the increased hardness of the mid-layer, and provides higher launch angles and lower driver spin with the enhanced outer hardness and inner softness. This new SRIXON golf ball realises not only longer flight performance, but also softer feeling and spin performance by featuring SeRM® in its coating.

Model Name: SRIXON Z-STAR XV – £44.99

More spin on short games without losing flight performance
The new two-layer core with the larger outer core promotes higher repulsion. SeRM® used in the coating delivers softer feel by contacting deep into face of the club, and outstanding spin control, without sacrificing flight performance.
