Abstract: A collapsible, insulated storage container includes a front wall and a rear wall, each wall having a lower edge, an upper edge and two side edges. The lower edges and a portion of the side edges adjacent the lower edges are secured and sealed together to provide a pouch. The remaining portions of the side and upper edges are separably connected by a zipper for opening and closing the container. A closable drain is provided in the pouch. A flange extending from the upper edge of the rear wall is equipped with grommets to receive rotatable fasteners secured to a support structure. Straps also may be provided to secure the container to the support structure.
