The Callaway HEX Black Tour, with greater spin separation is designed for optimised performance from tee to green.

The Callaway HEX Black Tour features a number of proprietary technologies that separate it from every other round, white, dimpled ball in the game. An innovative dual-core construction, durable cover material and HEX aerodynamics combine to make produce a five-piece ball with better spin separation and all-round performance than any other ball Callaway has released.

Spin separation refers to the "holy grail" of golf ball design: producing a ball that has a measured difference between the high spin generated by shorter approach shots and the optimal low-spin rates from the driver. Callaway's i-Core Technology has created a dual-core construction the maximises the difference in compression between the inner and outer layers. The soft inner core helps reduce spin off the tee, while the high-compression outer core increases spin closer the green.

Both the outer and inner mantles of the Callaway HEX Black Tour are made of ionomer blends. However, each is comprised of different ratios, affecting the resilience and hardness of each mantle. Together, the soft inner mantle and firm outer mantle protect the high-tec dual core, producing powerful ball speeds from a wider range of swing speeds.

The HEX Black Tour has improved durability thanks to Callaway's DuraSpin cover. Using a unique thermoplastic urethane blend, the HEX Black Tour prevents marks and scratches throughout the round and is very soft, giving players the high-performance feel they are seeking.

Finally, the HEX Aerodynamics produce 100 percent surface coverage, compared with round dimpled balls that traditionally cover around 88 percent. With an enchanced surface contour and a more consistent finish system, this pattern reduces drag, and promotes a stable, penetrating ball flight.
