Abstract: Golf club heads are described herein, and in one embodiment including a body with an exterior surface defining a first body volume of at least about 400 cm3. The body has a bottom portion, a top portion, a front portion, and a back portion. A face positioned at the front portion of the body and is configured to receive an impact.

The top portion silhouette profile defines the outer bounds of the top portion in an X-direction and Y-direction. At least one indentation can be located on the bottom portion below the crown silhouette profile. The removal of the at least one indentation from the bottom portion can create a second body volume that is at least 12 cm3 larger than the first body volume.
