Abstract: Examples of golf club shafts and methods to manufacture golf club shafts are generally described herein. In one example, a golf club shaft includes a first tubular portion formed from a first material and coupled to a second tubular portion having a plurality of layers formed from a second material and a third material. A reinforcing member is disposed in at least one of the plurality of layers and is formed from a fourth material. The reinforcing member extends a length that is less than or equal to a length of the second tubular portion. The first, second, third, and fourth materials are different from one another. Other examples and examples may be described and claimed.

Abstract: Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head may include a body portion having an interior cavity, a face portion enclosing the interior cavity, a first mass portion and a second mass portion coupled to the body portion, a port connected to the interior cavity, and a filler material injected into the interior cavity from the port. The second mass portion includes a top portion and a bottom portion oriented relative to each other at an angle at least partially corresponding to a contour of a portion of the toe portion edge. The mass of the top portion of the second mass portion is less than the mass of the bottom portion of the second mass portion. Other examples and embodiments may be described and claimed.

Abstract: Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head may include a body portion, and an internal mass portion comprising a material having a greater density than a material of the body portion, a height in a top-to-sole direction, a depth in a front-to-back direction, and a width in a toe-to-heel direction. The distance between the internal mass portion and a toe portion edge is substantially less than the distance between the internal mass portion and a heel portion edge. The volume of the internal mass portion increases in a top-to-sole direction, and the height of the internal mass portion is greater than the width of the internal mass portion. Other examples and embodiments may be described and claimed.

Abstract: Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are described herein. In one example, a golf club head includes a body portion having an interior cavity, a back opening portion, a back cover portion covering the back opening portion, a filler material at least partially filling the interior cavity, a first mass portion coupled to the back cover portion, and a second mass portion coupled to the back cover portion. The body portion may be made from a first material having a first density, and the back cover portion may be made from second material having a second density different from the first density. The diameter of the second mass portion may be greater than a diameter of the first mass portion. Other examples and embodiments may be described and claimed.

Abstract: Exemplary embodiments of golf bags, golf bag tops, and methods to manufacture golf bags and golf bag tops are generally described herein. In one example, a golf bag top may include a club divider portion and a handle portion. A club fastener portion may extend from the handle portion and may receive a golf club shaft. A magnetic portion in the club fastener portion may magnetically attract the shaft. A magnet cover portion may be coupled to the club fastener portion and may include a flap portion entirely or partially covering the magnetic portion that would otherwise directly contact the shaft. The flap portion may provide physical separation between the magnetic portion and the shaft without prohibiting magnetic attraction therebetween. Other embodiments may be described and claimed.

Abstract: Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head may include a body portion made from a first material with a first density and having an interior cavity, a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front portion, a back portion with a back wall portion including a back opening portion, a top portion with a top portion edge, and a sole portion with a sole portion edge. A back cover portion made from second material with a second density different from the first density is coupled to the body portion to close the back opening portion. The back cover portion includes a port extending through the back cover portion. A filler material is injected into the interior cavity from the port. A mass portion is inserted into the port to close the port. The mass portion made from a third material with a second density greater than the first density.

Abstract: 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 a top portion, a bottom portion, a toe portion, a heel portion, a front portion, a rear portion, and a body cavity. A solid wall structure may be located inside the body portion and spaced apart from an interior surface of the front portion to form a channel therebetween. The channel may include a lower channel region having a first maximum width, a middle channel region having a second maximum width, and an upper channel region having a third maximum width. The second maximum width may be greater than the first maximum width and greater than the third maximum width. Other examples and embodiments may be described and claimed.
