Abstract: A fitted cap case that has a cap cover assembly having a front cover and a rear cover, a cap base assembly having a front base and a rear base, and a bottom base assembly having a front bottom base and a rear bottom base. The front cover closes onto the front base. The rear base and the rear bottom base slide within a cavity defined between the front base and the front bottom base to elongate or reduce a predetermined distance between a cap mount protrusion and a notched edge. The front cover closes onto the front base, and the rear cover closes, whereby rear cover lateral edges are partially positioned onto first and second channels, and lateral edges relatively align with a base edge.
