The Callaway 08 Big Bertha Ladies driver has a 440cc titanium head that is slightly smaller than a men's clubhead to reduce the club's weight. When combined with its slightly longer shaft and core Callaway Golf technologies, the Callaway 08 Big Bertha Ladies driver allows a woman to maximize her swing speed for increased ball speed and longer distance. In addition, the CG has been strategically positioned to promote a draw and help reduce fades and slices.
