Srixon Q-Star Tour golf balls (2022) The core is encased in a firm mantle layer, which is in turn surrounded by a soft, urethane cover. While the 338-dimple pattern is designed to make the ball more stable in the wind, it is very thin to allow the grooves in wedges and short irons to grab it more efficiently and help golfers generate more spin on approach shots, chips, and pitches. Srixon gave the Q-Star Tour the same SpinSkin with SeRM cover coating on the Z-Star and Z-Star XV to further enhance short-game performance. The coating does not affect the ball on shots hit with woods and long irons but compliments the urethane cover around the greens for increased control. The Q-Star Tour has always had a lower compression and softer feel than the Z-Star and Z-Star XV, so it has always felt softer than those balls. While the compression has not changed with this update, 72, the mantle layer is slightly softer, so the overall feel is softer.
