Golf club head
 A golf club head is formed with a unitary, one-piece body including a top crown, sole plate, face plate and side skirt. The side skirt includes an opening, and a cap is configured to cover the opening. Preferably, the cap is connected to the side skirt by a snap fit or interference fit. The interior portion of the golf club head preferably includes a reinforcement structure which supports the face plate. Desirably, the reinforcement structure includes three vertical ribs which are connected to the top crown, face plate and sole plate to form part of the one-piece body.
