A golf club head includes a body having aa crown defining a perimeter of the club head, a sole opposite the crown, a toe end opposite a heel end, a back end, and a hosel, the body further including a club face, an exterior side, an interior side, a head center of gravity, and a weight member positioned on one of the exterior side or the interior side of the crown.
Claims20
A golf club head comprising:
- a golf club head body having:
- a club face,
- a crown defining a perimeter of the golf club head,
- a sole opposite the crown,
- a toe end opposite a heel end,
- a back end opposite the club face,
- an exterior surface, an interior surface, a head center of gravity,
- a discretionary weight,
- and a hosel,
- wherein a portion of the discretionary weight is a weight member permanently positioned adjacent the crown and a portion of the weight member projects above a crown surface, the weight member having a weight member center of gravity and an elongated arcuate shape along the crown,
- wherein the weight member is positioned to maximize a distance from the weight member to the head center of gravity,
- wherein a first end of the weight member is positioned toward the toe end,
- wherein a length of the weight member is measured along a center line of the weight member extending from the first end to a second end of the weight member,
- wherein the length of the weight member is in a range between 1.0 inch to 6.0 inches,
- wherein at least a portion of the weight member is composed of the same material as at least some portion the golf club head body,
- wherein the weight member has a weight ranging from 45 grams to 85 grams, and
- wherein the weight member comprises a high density region having a greater density than remaining regions of the weight member, and said high density region is located near the first end.
