The Callaway HX Hot has a new 3-piece construction that delivers blistering ball speed and surprisingly soft feel. The HX Hot also features the revolutionary HEX Aerodynamics for the consistent ball flight that has driven the HX Tour Golf Ball to success on the worldwide tours and at retail. Callaway's HX Hot Golf Ball boasts significant improvements over traditional 2-piece distance offerings. The new, highly resilient core ' essentially the ball's engine ' is super-fast and kick-starts a chain reaction that produces explosiveness of the HX Hot Golf Ball off the clubface. The revolutionary HEX Aerodynamics on the cover also are improved, with the hexagons and pentagons optimized to reduce drag, increase lift and maximize distance. In creating the HX Hot, Callaway Golf engineers successfully added feel to a distance ball by separating the high resilience core from its fast cover with a soft, thin boundary layer that reacts like rubber ' interacting at impact with the cover to ignite velocity while maintaining feel. The cover of the HX Hot Golf Ball also has been improved to reduce spin off the driver for a penetrating trajectory. Like other balls in the HX family, the HX Hot has 332 geometries on the cover, blanketing the surface of the ball with 100% coverage ' unheard of in competitors' golf balls and critical to the superior flight properties and overall performance of the HX Hot Golf Ball. Achieving 100% surface coverage allows Callaway Golf engineers to tune lift and drag properties of the ball in order to reduce distance-robbing initial drag and increase length-promoting lift during flight.
