  • Patent number: 10130858
    Abstract: A golf grip for a golf club is disclosed herein. The golf grip includes a closed end, an open end, a composite shell including a laminate composite fiber material, a foam layer, and a shaft cavity. The foam layer is inward of the composite shell. The shaft cavity extends from the open end towards the closed end. The shaft cavity is inward from the composite shell and the foam layer. In embodiments, the golf grip also includes a core tube inward of the composite shell and of the foam layer. The core tube forms a shaft cavity for receiving a shaft of the golf club.

  • Patent number: 9486678
    Abstract: A molded golf grip for a golf club includes first simulated wrap, and a second simulated wrap. The first simulated wrap includes a first wrap surface extending in a helical pattern. The first wrap surface includes a first wrap surface texture and a first wrap width that is less than a pitch of the helical pattern. The second simulated wrap includes a second wrap surface extending in a second helical pattern intertwined helically with the first wrap surface. The second wrap surface includes a second wrap surface texture that is different than the first wrap surface texture and a second wrap width that is less than the pitch. The first simulated wrap and the second simulated wrap are molded as a single body forming a shaft opening there within.

  • Patent number: 9302164
    Abstract: A golf grip for a golf club includes a cap, a body, a tip, and a grip surface. The body includes an under layer, a top layer, and a middle layer. The under layer includes a first color. The top layer includes a second color, different than the first color. The top layer is disposed on the under layer. The middle layer includes a third material. The middle layer is at least partially disposed between the under layer and the top layer. The tip is a portion of the under layer extending beyond the top layer and the middle layer. The grip surface extends between the cap and the tip. The grip surface is the radially outer surface of the body and includes the top layer, a plurality of exposed portions of the under layer, and a plurality of exposed portions of the middle layer.
