The body defines a chamber adapted to receive a golf club head and includes a heel end, a toe end, and a plurality of sidewalls. The headcover further includes a lattice structure formed unitarily on a portion of the body during the additive manufacturing process. The lattice structure extends over at least a portion of each of the plurality of sidewalls and the toe end of the body. ## Claims ### Claim 1 A headcover for a golf club, comprising: a body formed layer by layer along a build plane during an additive manufacturing process, the body including: a head portion defining a chamber adapted to receive a golf club head and including a body aperture disposed at a heel end of the head portion that is configured to provide access to the chamber; and a hosel portion extending outwardly from the head portion, wherein the head portion and the hosel portion of the body are defined by a lattice structure, wherein the lattice structure comprises a gyroid pattern, wherein a unit cell of the gyroid pattern includes a continuous network of interconnected concave and convex surfaces, wherein a hosel cutout is defined by a hosel frame at a heel end of the hosel portion, and wherein the body aperture and the hosel cutout are in direct fluid communication with one another and are configured to receive the golf club. ### Claim 2 (depends on 1) The headcover of claim 1, wherein the body includes a front wall, a rear wall, a top wall, and a bottom wall, and wherein the lattice structure extends over at least a portion of the front wall, the rear wall, the top wall, and the bottom wall. ### Claim 3 (depends on 2) The headcover of claim 2, wherein the body includes a frame formed from a solid material and having a first support beam extending around a periphery of the front wall and a second support beam extending around a periphery of the rear wall. ### Claim 4 (depends on 3) The headcover of claim 3, wherein the frame further includes a plurality of transverse support beams extending between the first support beam and the second support beam. ### Claim 5 (depends on 1) The headcover of claim 1, further comprising a fastening element including an end and a free end, wherein the end is coupled to the body and the free end is moveable between a first state where the free end is uncoupled from the body and a second state where the free end is coupled to the body. ### Claim 6 (depends on 5) The headcover of claim 5, wherein the free end of the fastening element includes a magnet that is configured to be selectively coupled to a recess formed in the body. ### Claim 7 A headcover for a golf club, comprising: a body formed layer by layer along a build plane during an additive manufacturing process, the body defining a chamber adapted to receive a golf club head and including a heel end, a toe end, and a plurality of sidewalls; and a lattice structure formed unitarily on a portion of the body during the additive manufacturing process, wherein the lattice structure includes a plurality of cutouts and extends over at least a portion of each of the plurality of sidewalls and the toe end of the body, wherein the lattice structure comprises a gyroid pattern wherein at least one of the plurality of sidewalls includes a front wall having a faceplate, wherein the body includes a frame having a first support beam extending around a periphery of a front wall, wherein the faceplate includes a center portion and a plurality of arms that extend outwardly from the center portion and connect to the frame at the periphery of the front wall, wherein a portion of the lattice structure is arranged between the faceplate and the frame at the periphery of the front wall, and wherein the arms of the plurality of arms are spaced apart by at least one air gap. ### Claim 8 (depends on 7) The headcover of claim 7, wherein the lattice structure comprises gyroid pattern. ### Claim 9 (depends on 7) The headcover of claim 7, wherein the plurality of sidewalls include the front wall, a rear wall, a top wall, and a bottom wall. ### Claim 10 (depends on 9) The headcover of claim 9, wherein a second support beam extends extending around a periphery of the rear wall. ### Claim 11 (depends on 7) The headcover of claim 7, wherein the frame further includes a plurality of transverse support beams extending between the first support beam and the second support beam. ### Claim 12 (depends on 7) The headcover of claim 7, further comprising a fastening element including an end and a free end, wherein the end is coupled to the body and the free end is moveable between a first state where the free end is uncoupled from the body and a second state where the free end is coupled to the body. ### Claim 13 (depends on 12) The headcover of claim 12, wherein the free end of the fastening element includes a magnet that is configured to be selectively coupled to a recess formed in the body. ### Claim 14 (depends on 7) The headcover of claim 7, wherein a body aperture and a hosel cutout extends between a hosel frame of a hosel portion and a heel beam disposed along the heel end of the body. ### Claim 15 A headcover for a golf club, comprising: a body formed layer by layer along a build plane during an additive manufacturing process, the body including: a head portion including a plurality of sidewalls and a lattice structure that forms at least a portion of each of the plurality of sidewalls; and a sleeve portion extending outwardly from the head portion, wherein the lattice structure extends over a portion of the sleeve portion, wherein the body includes a solid frame that is interconnected with at least one gyroid structure, wherein the solid frame includes a first support beam and a second support beam with at least one air gap disposed therebetween, wherein at least two transverse support beams extend between the first support beam and the second support beam along a top wall, the at least two transverse beams being spaced apart from one another and at least partially spaced from a perimeter of the top wall, and wherein the solid frame defines a chamber that is configured to receive the golf club. ### Claim 16 (depends on 15) The headcover of claim 15, wherein the lattice structure comprises a gyroid pattern. ### Claim 17 (depends on 15) The headcover of claim 15, further comprising a fastening element including an end and a free end, wherein the end is coupled to the body and the free end is moveable between a first state where the free end is uncoupled from the body and a second state where the free end is coupled to the body. ### Claim 18 (depends on 17) The headcover of claim 17, wherein the free end of the fastening element includes a magnet that is configured to be selectively coupled to a recess formed in the body. ### Claim 19 (depends on 17) The headcover of claim 17, wherein the solid frame of the body includes a groove that is configured to receive the free end of the fastening element. ### Claim 20 (depends on 15) The headcover of claim 15, wherein the solid frame defines a cutout, the cutout disposed at a heel end of the body, and wherein the cutout extends between a bottom wall and the sleeve portion.
