The Quartz golf ball is specifically designed for golfers who are serious about their game and demand exceptional distance and performance. This two piece ball, with a unique dimple design and high energy core, provides added height on every shot. This translates into superior distance and control, especially at slower swing speeds. In addition, Quartz has a thin, cut proof cover, to ensure better feel and improved playability. The clear cover material gives the balls a quartz like look.
