Abstract

A golf club head includes a club head body having a striking face, a soleplate, a crown, a toe, a heel and a hosel shaped and dimensioned for receiving a shaft. The club head body includes a body shell composed of the striking face, soleplate, crown, toe and heel, wherein the body shell has a reduced mass allowing for greater weight manipulation within the club head body.
