1. A golf club head comprising:
a heel and a toe opposite the heel;
a metallic front body including a strike face and a surrounding frame that extends rearward from a perimeter of the strike face; wherein the strike face has a centerpoint, a loft plane tangent to the centerpoint along the strike face, and a midplane extending through the centerpoint from the heel to the toe and perpendicular to the loft plane;
a rear body coupled to the metallic front body,
wherein the rear body and the metallic front body form a substantially hollow structure with a cavity therebetween,
wherein the rear body comprises a crown member and a sole member,
wherein the sole member is coupled to the crown member, and
wherein the sole member comprises:
a structural layer formed from a molded thermoplastic material, the structural layer including a plurality of apertures extending through a thickness of the structural layer,
a resilient layer bonded to an external surface of the structural layer such that the resilient layer extends across each of the plurality of apertures;
a metallic weight pad bonded to the structural layer, wherein the metallic weight pad comprises an aperture for the attachment of a metallic weight; and
a structural member extending upwards from the metallic weight pad and toward the crown member; and
a head center of gravity located at a head CG depth from the loft plane, measured in a direction perpendicular to the loft plane, and at a head CG height from the midplane, measured in a direction perpendicular to the midplane; wherein the head CG depth is greater than 1.7 inches;
wherein the crown member comprises a non-metallic material;
wherein the golf club head further comprises an encapsulating layer between the metallic weight pad and the structural layer of the sole member; and
wherein the encapsulating layer is a structural tape that extends over an edge of the metallic weight pad and forms an adhesive bond between the metallic weight pad and the structural layer of the sole member.
