Patent ID: 7651412

Claim:
A golf club head, comprising: a face, a crown, a sole, and a skirt coupled together to form a club head body having an interior volume; said face having a strike surface and an inner surface opposite said strike surface, said face having a point of maximum coefficient of restitution and a geometric center; and a coefficient of restitution lowering insert coupled to said inner surface of said face extending completely across the inner surface of the face from heel to toe within said interior volume, wherein said insert includes a material selected from the group consisting of composites, resin systems, thermoset materials, thermoplastic materials, pitch based carbon fibers, PAN based carbon fibers, para-aramid fibers, fiberglass fibers, spectra fibers, or combinations thereof; wherein said point of maximum coefficient of restitution is between said crown and said geometric center; and wherein said insert is coupled to said face such that said face has a coefficient of restitution between said sole and said geometric center that is substantially less than a coefficient of restitution between said crown and said geometric center.
