The new HX Diablo Tour provides the optimum combination of distance, feel and control in a 3-piece performance golf ball. The Power Reaction Core has a soft center and gradually gets firmer toward the outer edge, creating lower spin off the driver for more distance and more spin around the green for better control. The DuPont HPF inner cover increases ball speeds and the soft cover provides incredible feel. HEX Aerodynamics reduces drag and promotes strong trajectories in varying wind conditions. Power Reaction Core The strategic design creates a soft center that gradually gets firmer toward the outer edge, generating lower driver spin for increased distance while also providing excellent greenside control. Soft Ionomer Cover Produces incredible feel off the clubface with increased short-game spin for aggressive shot-making. Advanced DuPont HPF Inner Cover Creates faster ball speeds and helps lower driver spin for longer, more accurate shots. Hex Aeordynamics Similar to honeycomb covering a beehive, Callaway’s patented HEX Aerodynamics produce 100% surface area coverage on a golf ball whereas traditional round dimples typically cover only 88% of the surface. Dead space between dimples can cause inefficient flight characteristics so HEX geometries cover the entire ball to reduce drag and cut through air with a strong, penetrating ball flight.
