MY SHELL JACKET WILL NOT STAY DRY ANYMORE. WHAT CAN I DO ABOUT IT?
All of The North Face Outerwear shell fabrics are treated with a Durable Water Repellent finish (DWR). This finish helps the shell fabric resist wetting by causing the water to bead-up so it easily falls off before being absorbed into the fabric. Additionally, some of our performance fabrics have a waterproof back finish (such as GORE-TEX® fabrics and HydroSeal®) that prevents penetration of the water through the fabric. As a garment is worn and used over time, accumulation of soils from external sources as well as from your own body can lessen the performance of these finishes.
In order to revive the DWR, follow the cleaning instructions on a tag inside the garment. In most jackets, you will find the tag stitched in the seam at the waist. When cleaning your garment, attach all Velcro® closures and zip all zippers. It is recommended to put the product through two rinse cycles to ensure that there is no detergent residue. The entire outside of the garment can also be touched up with a warm iron on the steam setting after laundering to aid in restoring the DWR properties.
This process should revive the DWR. For even better performance, treat your product with a coating of a DWR spray such as Tectron®. This maintenance program is only required when water stops beading up on the outer surface of the fabric.
