Abstract: The present invention is directed to a collapsible, shapeable hat. Exemplary embodiments of the collapsible, shapeable hat include a crown and a brim, the crown composed of material shaped to cover a head and including an outer edge, the brim extending from the outer edge of the crown and brim including an interior region and an outer perimeter. The interior region is composed of pliant material. The brim is joined to the outer edge of the crown and extending distally from the outer edge such that the interior region is adjacent the outer edge and the outer perimeter is further distal to the crown. A semi-rigid line is secured to the brim, the semi-rigid line being a semi-rigid length of material granular manipulable laterally and longitudinally substantially along its entire length, enabling lateral and longitudinal manipulation along the majority of points of its length.
