Callaways most advanced hybrid ever is built like a driver, with exceptional ball speed and forgiveness from a wide variety of shots. Great Big Bertha now features a titanium face and body, allowing engineers to leverage 100g of the weight savings into increasing ball speed, forgiveness and an easier launch. The titanium face is uniquely optimized in every hybrid face to enhance speed and spin, especially on off-center hits. A.I. Designed Jailbreak Speed Frame is paired with Batwing Technology to increase stiffness around the perimeter to allow for more optimal face flexing. The Carbon Sole and Triaxial Carbon Crown save significant weight compared to steel, which has been redistributed to enhance CG and higher launch. Two internal tungsten weights and the sole plate promote faster ball speeds. The sole has been redesigned with more camber to improve turf interaction and versatility from tougher lies. The refined shaping creates a more compact, fairway wood-like head.
