In one example, a golf club may include a club head coupled to a shaft. The club head may include a body portion having an interior cavity, a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, a crown portion with an opening, a polymer insert in the interior cavity, and a non-metal cover portion coupled to the crown portion to cover the opening. Other examples and embodiments may be described and claimed. ## Claims ### Claim 1 A golf club comprising: a shaft; a club head coupled to the shaft, the club head comprising: a body portion having an interior cavity, a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, and a crown portion, the crown portion having an opening; a polymer insert in the interior cavity, the polymer insert in contact with an inner surface of the bottom portion; and a non-metal cover portion coupled to the crown portion to cover the opening, the non-metal cover portion comprising: a top layer comprising a composite material; a middle layer adjacent to the top layer, the middle layer comprising a polymer material; and a bottom layer adjacent to the middle layer, the bottom layer comprising a composite material. ### Claim 2 (depends on 1) A golf club as defined in claim 1, wherein the top layer is bonded to the middle layer. ### Claim 3 (depends on 1) A golf club as defined in claim 1, wherein the middle layer is bonded to the bottom layer. ### Claim 4 (depends on 1) A golf club as defined in claim 1, wherein the non-metal cover portion is coupled to the crown portion by an adhesive. ### Claim 5 (depends on 1) A golf club as defined in claim 1, wherein the polymer insert includes a plurality of hexagonal recesses. ### Claim 6 (depends on 1) A golf club as defined in claim 1, wherein the polymer insert comprises a thermoplastic elastomer material. ### Claim 7 (depends on 1) A golf club as defined in claim 1 further comprising a plurality of weight portions on the bottom portion. ### Claim 8 A golf club comprising: a shaft; a club head coupled to the shaft, the club head comprising: a body portion having an interior cavity, a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, and a crown portion, the crown portion having a recess; a polymer insert in the interior cavity, the polymer insert in contact with an inner surface of the bottom portion; and a non-metal cover portion coupled to the crown portion within the recess, the non-metal cover portion comprising: a top layer comprising a composite material; a middle layer adjacent to the top layer, the middle layer comprising a polymer material; and a bottom layer adjacent to the middle layer, the bottom layer comprising a composite material. ### Claim 9 (depends on 8) A golf club as defined in claim 8, wherein an outer surface of the non-metal cover portion is flush with an outer surface of the crown portion. ### Claim 10 (depends on 8) A golf club as defined in claim 8, wherein the crown portion comprises a shoulder that supports the non-metal cover portion. ### Claim 11 (depends on 8) A golf club as defined in claim 8, wherein a thickness of the recess in the crown portion is substantially similar to a thickness of the non-metal cover portion. ### Claim 12 (depends on 8) A golf club as defined in claim 8, wherein the polymer material of the middle layer comprises an elastic polymer. ### Claim 13 A golf club comprising: a shaft; a club head coupled to the shaft, the club head comprising: a body portion having an interior cavity, a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, and a crown portion, the crown portion having a first opening and a second opening separated by a reinforcement portion; a polymer insert in the interior cavity, the polymer insert in contact with an inner surface of the bottom portion; a first non-metal cover portion coupled to the crown portion to cover the first opening, the first non-metal cover portion comprising a first composite top layer, a first polymer middle layer adjacent to the first composite top layer, and a first composite bottom layer adjacent to the first polymer middle layer; and a second non-metal cover portion coupled to the crown portion to cover the second opening, the second non-metal cover portion comprising a second composite top layer, a second polymer middle layer adjacent to the second composite top layer, and a second composite bottom layer adjacent to the second polymer middle layer. ### Claim 14 (depends on 13) The golf club of claim 13, wherein a thickness of the reinforcement portion is between about 2% and about 30% of a width of the reinforcement portion. ### Claim 15 (depends on 13) The golf club of claim 13, wherein a thickness of the reinforcement portion is between about 3% and about 15% of a distance between the toe portion and the heel portion. ### Claim 16 (depends on 13) The golf club of claim 13, wherein the reinforcement portion is integral with the body portion. ### Claim 17 (depends on 13) The golf club of claim 13, wherein the reinforcement portion is joined to the body portion. ### Claim 18 (depends on 13) The golf club of claim 13, wherein the crown portion comprises a crown perimeter portion that surrounds the first opening, the second opening, and the reinforcement portion. ### Claim 19 (depends on 13) The golf club of claim 13, wherein the first opening extends from a location proximate to the front portion to a location proximate to the rear portion and extends from the reinforcement portion to a location proximate to the toe portion. ### Claim 20 (depends on 13) The golf club of claim 13, wherein the second opening extends from a location proximate to the front portion to a location proximate to the rear portion and extends from the reinforcement portion to a location proximate to the heel portion.
