The lowest-spinning Callaway® driver yet, the men's Big Bertha Alpha 815 Double Black Diamond is designed for expert players who want maximum distance. The ultra-light R-MOTO face saves over 3 grams of weight, which are put back into the club to push the CG lower for more speed. Ultimate adjustability is achieved through Gravity Core tuning, movable weights, and an OptiFit hosel.
