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.
