Abstract: A collapsible durable outdoor adventure container is constructed of polymer sheeting having holes in flaps of the sheeting. The sheet is bendable and bent by a user to a selected tubular configuration to align through holes along a seam line in flaps of the sheet or sheeting assembly with cable tie clamping elements clamping said flaps together through the holes. A strap coupled to at least several of the clamping element running along the seam line acting as an outside wrapping and/or tensioning element to contain the clamped flaps and fully or partially contain the contents of the container providing a connection tensioning element between adjacent clamping elements as connected along the seam line of the flaps.
