The stars love it - but what's new? Hannah Holden takes a closer look

Can you believe this is the seventh generation of the Z-star? It’s back for 2021 with some serious technology upgrades and it looks like it’s been impressing on tour already.

Reigning Open champion Shane Lowry has put the ball straight in his bag, while Ryan Fox says he’s “played every model of the ball since its inception and this new one’s the best one yet.”

He added: “It’s great in the wind, heaps of speed off the driver, and lots of control around the greens. You guys will love it.”

US Open champion and Ryder Cup legend Graeme McDowell added his thoughts on Twitter:

As did three-time PGA and European Tour winner Russell Knox:

So what’s new? Let’s take a look…

2021 Srixon Z-Star: The line-up

There are two golf balls in the new line up. First the Srixon Z-Star is a three-piece ball which has the highest spin and also has the softest feel of the two Z-Star offerings. It is designed to have a mid-height trajectory.

The Srixon Z-Star XV is a four-piece ball with a smaller inner core. It is designed to fly higher and be slightly firmer than the standard Z-Star model. This is also designed to be the longest ball in the line-up.

The Z-Star is renowned for being a long golfer ball thanks to players such as Cameron Champ putting them in play on the PGA Tour. The key tech behind this is the FastLayer Core which is soft in the centre and gradually becomes firmer as you move out to the edges. This combines speed with ideal launch conditions.

The outer cover has been thickened to provide more spin and control around the green as well as a softer feel. When this thicker cover is combined with the FastLayer Core you also see a jump in ball speed giving you more distance.

Each offering has new spin skin technology with slide-ring material (SeRM). This adds flexible bonds between the urethane cover molecules which makes them stronger and more flexible. This flexibility allows the ball cover to dig deeper into wedge and iron grooves giving you more spin, control, and stopping power.

Again both balls also featured a 338-dimple pattern that improves aerodynamics – especially in windy conditions – but this year the dimples are slightly shallower.
