Engineered with tour ball technology, the Q-STAR delivers a superior combination of distance, accuracy, greenside spin and durability. SECOND GENERATION SPINSKIN The new coating increases the frictional force at impact by 18% compared to the previous version resulting in even more greenside spin, control, and a softer feeling ball. 324 SPEED DIMPLE PATTERN Next generation Speed Dimple technology combines higher dimple uniformity and surface coverage to create a more aerodynamic design with less drag, resulting in longer distance and a truer ball flight in any wind condition.
