Multi-component golf club head
Embodiments of wood-type club heads comprising one or more components are described herein. The wood-type club head comprises a first, metallic component, and a second, non-metallic component. The first component comprises the load bearing structure that forms the striking face, and portions of the crown, the heel, the toe, and the sole. The second component comprises a lightweight structure that wraps around the first component to form portions of the crown, the heel, the toe, and the sole. The first component comprises mass pads and receives removable weights to adjust the weight properties of the club head. The two-component design allows for additional discretionary mass redistribution to improve center of gravity location and moment of inertia.
