Abstract: A bag which is light in weight and which assumes a relatively rigid structure which maintains its shape during use includes a bladder having opposing lateral edges and a fabric panel having opposing lateral edges which are joined to the opposing lateral edges of the flexible bladder to form an enclosure having a bottom and side walls defined by the flexible bladder and a top defined by the fabric panel. In addition to providing sufficient rigidity, the inflated bladder also provides a cushioned support and enclosure for articles contained therein. The combination of an inflated bladder joined along opposing lateral edges to a fabric panel, in addition to achieving sufficient stiffness and rigidity in a lightweight bag, can be easily fabricated using relatively few components.
