The new Big Bertha Hybrids are the first hybrids ever to combine innovative Jailbreak Technology with adjustability for fast ball speeds, long distance, and easy launch. Jailbreak bars stiffen the body, placing more impact load on the face to promote fast ball speed and long distance. Carpenter 455 steel face, Jailbreak Technology and Hyper Speed Face Cup combine to maintain high ball speeds across the face. A new hosel system that�s shorter and lighter to save weight. That weight is repositioned to optimize Center of Gravity for easy launch and high, long-carrying ball flight. Progressive head shape that�s both forgiving and appealing, and packed with high MOI technology.Standard Callaway warranty applies and satisfaction is guaranteed. Headcover included.
