Thin , Premium Urethane Cover with Biomass- Every Q-STAR TOUR golf ball features an extra thin, premium urethane cover for tour-caliber greenside spin, feel, and control. Our latest covers are also made with Biomass—a durable, plant- derived material requiring fewer carbon emissions to manufacture. It’s our signature, unbeatable performance and feel, plus a step toward reducing environmental impact. FastLayer Core- FastLayer uses a contrasting compression effect across the core to generate better ball speeds and distance. Q-STAR TOUR’s unique FastLayer formula also offers a lower compression rating—helping players hit longer, straighter shots on low-lofted clubs and achieve a satisfying, softer feel on Iron and Wedge shots. Spin Skin+ Coating- A durable coating, Spin Skin+ digs deep into Wedge and Iron grooves, maximizing spin for better control and stopping power, while also improving the cover’s resistance to dirt and grime. 338 Speed Dimple Pattern- The 338 Speed Dimple Pattern on Q-STAR TOUR improves overall aerodynamics for better flight performance. A lower drag coefficient helps the ball cut through the air with less resistance for a more penetrating launch and straighter flight. A higher lift coefficient allows the ball to stay airborne longer for maximum distance.
