1. A golf club head comprising:
- a crown, a sole, a skirt anda face, the face including a geometric center defining a center face location, the head having a center of gravity,wherein a reference tangent face plane is defined as a plane tangent to the face at the center face location,wherein the center of gravity defines a projection orthogonal to the tangent face plane and passing through the center of gravity such that a projection point is defined at the intersection of the projection and the tangent face plane,wherein a reference ground plane is defined along a bottom end of the body, the ground plane thereby being below the golf club head, andwherein the projection point is below the center face location;
a body,wherein the golf club head defines an exterior and an interior that is bounded by the crown, the sole, the skirt and the face;
the face and the body together defining the center of gravity, the center of gravity being proximate the face;
a coefficient of restitution feature (CORF) defined in the sole of the golf club head;
wherein the coefficient of restitution feature defines a gap in the body in the form of a through slot providing a port from the exterior of the golf club head to the interior, wherein the through slot is at least partially filled with a plugging material to prevent debris from entering the interior,the golf club head further comprising a weight pad located proximate to the CORF, the weight pad having a weight that is 35 to 50 percent of a total weight of the golf club head.

Abstract
A golf club head includes a face; a body, the body defining an interior and an exterior; the face and the body together defining a center of gravity, the center of gravity being proximate the face; a coefficient of restitution feature defined in the body; wherein the coefficient of restitution feature defines a gap in the body. A golf club head includes a face and a golf club body; the face and the golf club body defining a center of gravity, the center of gravity defined a distance, Δz, from a ground plane as measured along a z-axis, the center of gravity defined a distance, CGy, from the center face along the y-axis.

10. A golf club head comprising:
-
a body having a crown, a sole, a skirt and a face, the face including a geometric center defining a center face location, the body having a center of gravity proximate to the face; wherein a reference tangent face plane is defined as a plane tangent to the face at the center face location, wherein the center of gravity defines a projection orthogonal to the tangent face plane and passing through the center of gravity such that a projection point is defined at the intersection of the projection and the tangent face plane, wherein a reference ground plane is defined along a bottom end of the body, the ground plane thereby being below the golf club head, and wherein the projection point is below the center face location; wherein the body defines an exterior and an interior bounded by continuous walls on all sides except for a through slot located in the sole proximate to the face, which decouples the face from the sole; a plugging material at least partially filling the through slot without interfering with the decoupling of the face from the sole; whereby the through slot creates a passage between the exterior and interior if the plugging material is removed; including a weight pad located proximate to the through slot, the weight pad having a weight that is 35 to 50 percent of the total weight of the golf club head. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
