Callaway Golf engineers set out looking for breakthrough ball speed enhancements that would set a new standard in a crowded all-titanium driver market. The innovative Hyper X Driver provides a new benchmark in performance with the introduction of Hyperbolic Face Technology, redefining the look, feel and speed at which golf balls leave the clubface. Eight years in the making, our engineers have sculpted a more ball speed robust face that dramatically increases impact efficiency for greater distance on shots hit across the entire face. The 460cc head shape has been optimized for a high MOI while maintaining a traditional look. The advanced Fujikura® shaft adds to the driver's incredible feel and performance.
