You can totally restore the water repellency (DWR) by using a topical DWR treatment product for outdoor fabrics, available at outdoor retail stores. (Note: We do not recommend wash in treatments.) These special treatments help maintain and restore the DWR on the outer shell fabric of the product so that it remains water and stain repellent. Anyone can properly maintain the DWR. When water no longer beads on your garment's outer fabric, simply apply a topical DWR treatment product according to its directions.
