Abstract

A golf club head has a body having a ball striking face, a rear opposite the ball striking face, a crown, a sole, a heel, and a toe, the body having a void defined by a peripheral edge on the sole. The body further defines a cover that extends over the void and forms at least a portion of the crown. At least a portion of the peripheral edge of the void includes a lip extending from the peripheral edge inwardly into the void. The golf club head may additionally or alternately include one or more weight receptacles connected to the sole and having an opening in the sole, such that each weight receptacle is configured to receive insertion of a weight through the opening.
