This invention relates to a collapsible article of luggage or bag in which a plurality of pivotally mounted reinforcing panels and corner insertions permit the luggage to assume either a rigid or semi-rigid configuration or collapsed space-saving shape. Additionally, the top and bottom enclosure are secured to each other by a continuous zipper or slide fastener. This provides for ease of assembly by the manufacturer by merely zippering or fastening these elements together and welding the zipper at two points along its length to provide for permanent attachment of the top member to the bottom enclosure.
