Groundbreaking technologies combine to form the Callaway Epic Flash Fairway Wood. Flash Face Construction – the first known application of A.I. in golf equipment – employs data from over 15,000 face architecture iterations to strategically place dozens of subtle ripples on the back of the face to generate noticeable distance gains. Jailbreak Technology uses two internal bars to stabilize the crown and sole for even greater ball speed. A fixed back weight combines with a new, lighter OptiFit Hosel to optimize CG placement and customization.
