Abstract
To prevent a top panel of a crown of a collapsible hat from being crushed and creased, first portions of a frame member extending along a periphery of a brim of the hat are folded to overlap an exterior side of the top panel, and second portions of the frame member are folded to overlap an interior side of the top panel. The frame portions maintain a neat appearance for the top panel even after the hat has been repeatedly collapsed.
