Abstract

A hollow golf club head with a concave portion is disclosed and claimed. The club head includes a metallic portion and a light weight portion, which may be formed of plastic, composite, or the like. The concave portion allows the club designer to make a club head having very thin portions while still maintaining the requisite structural integrity. Convex bulges may optionally be provided to house weight inserts to enhance the playing characteristics of the golf club.

wherein the first body member comprises a first material having a first density and first thickness, and the second body member comprises a second material having a second density and second thickness;

wherein the second density is less than the first density, and the second thickness is less than the first thickness.

2. The golf club head of claim 1, wherein at least one weight member is positioned within the at least one convex bulge.
