Callaway Great Big Bertha Epic Driver

GBB Epic is so-named because it represents an epic shift in how the head and face behave to enhance power, spearheaded by our innovative Jailbreak Technology and Exo-Cage/triaxial carbon construction. Any golfer, from scratch players to high handicappers, should find more speed, distance and control with GBB Epic.
Our patent-pending Jailbreak Technology profoundly changes how the head behaves to increase ball speed and distance. At impact, a driver’s crown, sole and face each bend, flex and rebound. Jailbreak positions two ultra-light (3g), ultra-strong titanium bars behind the face, connected to the crown and sole. Jailbreak bars reduce crown and sole deflection, allowing the face to take on more impact-load to focus more energy – physicists call this “energy lensing” — across more of the face to promote longer average distance from swing to swing.
