ABSTRACT OF THE DISCLOSURE An improved weatherproof dunnage bag for use in an open freight transport vehicle is provided. The bag includes an air bladder for expanding the bag and a plurality of air bladder reinforcing sheets enclosing the bladder. The outer- most sheet is coated with a moisture resistant material and a moisture resistant overslip is provided surrounding each of two opposite ends of the bag. The overslips are heat sealed to the outermost sheet, so that the overslips and coating on the outermost sheet prevent moisture from pervading the sheets. A valve extending through the sheets from the bladder of the bag protrudes through an opening in one of the overslips, the opening having a diameter substantially equal to the inside diameter of the valve, so that the overslip fits tightly around the valve to prevent moisture from leaking into the bag around the valve. A moisture resistant tape is provided covering each seam in the outermost sheet.
