Z-Star XV has long been Srixon's firmest, fastest tour ball, and the 2025 version keeps that role with the same FastLayer DG Core architecture as the standard Z-Star but with added firmness through the core for lower driver spin and a mid-to-high flight. It's built for players above roughly 105 mph of swing speed who want distance without giving up short-game control.
Firmer off the tee than Z-Star with lower long-game spin, but the urethane cover keeps wedge spin competitive despite the added firmness.
Suited to faster swing speeds chasing distance and a flatter flight; slower swingers will likely find it too firm to compress properly.
A step behind the standard Z-Star in used-market volume, but still a reasonable recovered-ball find for fast-swing players.
