The Callaway HX Tour is becoming one of the most popular balls in professional golf. Played by the queen of the ladies’ game, Annika Sorenstam, and 2005 U.S. Open winner Michael Campbell, the HX Tour is a thin-covered, high energy ball that gives golfers amazing stopping power around the flag. The Sub-Hex dimple design promotes a consistent ball flight while also contributing to a very durable and resilient cover.
