In one example, a golf club head may include a body portion having a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, a top portion, and a crown portion covering an opening in the top portion. The crown portion may include an inner composite layer, an outer composite layer, and a toe-side integral rib disposed between the inner composite layer and the outer composite layer. The toe-side integral rib may extend rearward from a toe-side integral rib starting location between a vertical plane of the golf club and a toe-side golf ball plane and terminate at a toe-side integral rib ending location between a toe-side bounding plane and the toe-side golf ball plane. Other examples and embodiments may be described and claimed. ## Claims ### Claim 1 A golf club head comprising: a body portion comprising a front portion, a rear portion, a toe portion, a heel portion, a bottom portion, an interior cavity, and a top portion defining an opening to the interior cavity;
