The Callaway HEX Black Tour golf ball strikes the perfect balance of Tour performance for both the distance-seeker and the control freak. Engineered with a highly durable Urethane cover, this ball is designed for Optimized Tour Performance. HEX Black Tour promotes low spin off the tee for more distance in your long game and high spin on approach shots for total control and aggressive stopping power into the green. From powerful ball speeds to a penetrating ball flight and soft feel, this golf ball offers the ultimate blend of Tour Distance with Tour Control. HEX Aerodynamics has a refined pattern that provides the best aerodynamic performance ever in a Callaway golf ball. I-Core Technology combines a soft inner core with a firm outer core. Dual mantle layers help reduce driver spin. DuraSpin cover uses a proprietary formulation to significantly improve durability.
