Callaway Big Bertha Reva is a forgiving hybrid with a large club head and offset design. Big Bertha Reva is specially developed for ladies where the loft, swing weight and shape of the head have been optimised to produce long shots. With tungsten weights placed in the sole, you get an optimal launch angle and plenty of forgiveness. The offset design helps to minimise slice. Callaway’s Flash Face SS21 has been developed using artificial intelligence in a supercomputer and, together with Jailbreak technology it produces high ball speed and good distance, even on off-centre shots.
