Hat comprising a variable circumference aperture

A hat comprising:

• a domed crown defining an interior cavity for receiving a head of a wearer when worn;
• wherein the domed crown comprises:
• a front portion,
• a rear portion,
• a headband, and
• an elastic band;
• wherein the rear portion of the domed crown comprises a first rear panel and a second rear panel;
• wherein the first rear panel comprises a first arcuate edge, a first end edge, and a first top connection edge, and the second rear panel comprises a second arcuate edge, a second end edge, and a second top connection edge;
• wherein the first arcuate edge partially overlaps the second arcuate edge;
• wherein the first top connection edge is permanently fixed to the second top connection edge;
• wherein the first rear panel and second rear panel each comprise an elastic connector;
• wherein the elastic connectors connect the first end edge of the first rear panel to a first nonadjacent side panel, and the second end edge of the second rear panel to a second nonadjacent side panel;
• wherein the overlapping arcuate edges form a shape defining an aperture;
• wherein the shape comprises a top and a bottom;
• wherein the top of the shape is fixed in place;
• wherein the bottom of the shape is motile;
• wherein a circumference of the shape can be increased by manipulating the bottom of the aperture;
• wherein the elastic band comprises:
• a first portion coupled to a periphery of the first arcuate edge, and
• a second portion coupled to a periphery of the second arcuate edge;
• wherein the elastic band transitions from the first arcuate edge to the second arcuate edge in an overlapping manner such that it forms a loop;
• and wherein the elastic band exerts an elastic force when a circumference of the aperture is increased.
