  • Patent number: 9839823
    Abstract: A golf club head comprising a crown with an edge support structure and a flexible, conformal weight sized to fit within the edge support structure is disclosed herein. The edge support structure preferably is disposed on an internal surface of the crown so that the conformal weight is invisible when the golf club head is viewed at address. The conformal weight can be removed to adjust the vertical center of gravity of the club head, and preferably is oriented in a front-to-back direction along the club head's X-axis. The conformal weight preferably is composed of a high-density polymeric material with a specific gravity ranging from 1.8 to 4.2.

  • Patent number: 9433833
    Abstract: A golf club head comprising an aerodynamic hosel is disclosed herein. In one embodiment, the hosel has an upper portion and a swept transition portion which connects to the golf club head, and all points at which the swept transition portion contacts the club head are spaced rearwardly from a vertical face plane. In a further embodiment, both the upper portion and the swept transition portion comprise coaxial shaft receiving bores. In yet another embodiment, the swept transition portion of the hosel has a trailing edge that is truncated, or that has one or more surface discontinuities. In yet another embodiment, the swept transition portion has a height and a diameter, each of which is less than or equal to one inch.
