Abstract

The invention provides a golf club head with an opening covered from within by a lightweight cap. The opening can be part of, e.g., a weight track. The club head includes a crown, sole, face, and hosel cooperating to define a hollow club head body comprising at least a first material. The club head has an opening through the hollow body. Part of an edge around the opening is provided by a first material and a cap member of a second material less dense than the first material is mounted e.g., by an adhesive to an inside surface of the hollow body and enclosing the opening. The described construction is easier to mold or cast that other forms featuring undercuts and does not unduly interfere with a club head center of gravity.
