Abstract: A garment with a convertible collar includes a garment, a collar secured to the garment and defining a pouch with an open-top end, and a fleece-like sheet secured to the garment. The sheet is movable between a storage orientation, wherein substantially all of the sheet extends through the open-top end of the pouch and lies flat within the pouch, and a use orientation, wherein the sheet is substantially disposed outside of the pouch and overlies substantially all of the upper surface of the collar. Fasteners on the collar and the sheet releasably maintain the sheet in the use orientation, and fasteners on the pouch and the sheet releasably maintain the open-top end substantially closed when the sheet is in the storage orientation.
