A golf club head, when oriented in a reference position, includes: a striking face; a top portion; and a sole portion opposite the top portion. The sole portion includes a leading edge, a trailing edge, at least one sole rail generally elongate in a front-to-rear direction, and a sole contact point located on the at least one sole rail. In a virtual vertical plane extending in the front-to-rear direction and passing through the sole contact point, (i) the sole portion includes a sole length Ls measured in the front-to-rear direction from the leading edge to the trailing edge and (ii) the sole contact point is spaced rearwardly from the leading edge by a distance D1 no greater than 0.8*Ls.

Embodiments of a golf club head with a plurality of energy storage features are presented herein. In some embodiments, a golf club head comprises a body comprising a strike face, a heel region, a toe region opposite the heel region, a sole, a crown, a channel, a chamfer spanning between a strike face and the crown, and an internal radius transition feature from the strike face to at least one of the sole or the crown.

A golf club head including a striking face, a back portion, and a back cover attached to the back portion, wherein the golf club head includes damping structures and materials to achieve desired acoustic characteristics.

Golf club heads are described having a club head portion, a shaft portion connected to the club head portion, and a grip portion connected to the shaft portion. The club head portion has a heel portion, a sole portion, a toe portion, a crown portion, a hosel portion, and a striking face. The striking face can have a center face roll contour, a toe side roll contour, a heel side roll contour, a center face bulge contour, a crown side bulge contour, and a sole side bulge contour. The toe side roll contour can be more lofted than the center face roll contour. The heel side roll contour can be less lofted than the center face roll contour. The crown side bulge contour can be more open than the center face bulge contour, and the sole side bulge contour can be more closed than the center face bulge contour.

A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.

Described herein are embodiments of golf club heads having a balance of the following parameters: a low and back club head center of gravity position, a high moment of inertia, a large Ixy product of inertia, and low aerodynamic drag. Methods of manufacturing the embodiments of golf club heads having a balance of club head center of gravity position, moment of inertia, product of inertia, and aerodynamic drag are also described herein.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having an interior cavity, a front portion, a back portion, a toe portion, a heel portion, a sole portion, and a top portion. A face portion is attached to the front portion to enclose the interior cavity. The golf club head may further include a port on the body portion that is connected to the interior cavity. A first mass portion may be coupled to the body portion such that the port is configured to receive the first mass portion to close the port. A second mass portion may be coupled to the body portion and include a different material than a material of the first mass portion. The maximum width of the interior cavity may be below a horizontal midplane of the body portion and above the port. The interior cavity may be at least partially filled with a filler material from the port. The interior cavity may at least partially extend over the port at a location of the maximum width. Other examples and embodiments may be described and claimed.
