Callaway engineered the new Women's Big Bertha REVA 23 family of golf clubs specifically to meet the needs of the female golfer, utilizing player feedback and data to create a best-in-class lineup. �With REVA 23, women of skill levels will reap the rewards of more distance, accuracy, forgiveness, and a high, easy launch. Designed for playability and players who prefer hybrids over long irons, the Big Bertha 23 Hybrids feature a large, high-volume head shape that provides maximum forgiveness. �Callaway utilized pinpoint-located tungsten weights inside the club head and an offset design to deliver a towering ball flight and a slice-fighting, straighter shot shape. Instead of selecting a shaft from a 3rd party manufacturer, Callaway crafted the RCH shaft to mesh perfectly with the REVA 23 Hybrid and enhance its performance. �Those who fear irons can build a nearly complete set of Bertha Hybrids thanks to head lofts ranging from four through nine.
