How can I restore my garment's water repellency?
You can totally restore a GORE™ product's durable 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 on a GORE™ product.
When water no longer beads on your garment's outer fabric, simply apply a topical DWR treatment product according to its directions.
Why do I need to use a water-repellent treatment on my GORE-TEX® product?
Gore shell fabrics, the outermost fabric layer of a GORE-TEX® garment, are treated with an ultra-thin polymer coating known as DWR, or durable water repellent. This coating causes water to bead up and roll off the outer layer of fabric, instead of being absorbed.
Water-repellent outer fabric provides additional insulation and prevents liquid from saturating your garment's outer fabric, a condition known as "wet out" that can make you feel damp and clammy. Your garment may even feel like it's leaking, although it's not.
Regular wear and tear, plus exposure to dirt, detergents, and other impurities, causes DWR failure. The effective life of the DWR depends upon how you care for your garment and how rigorously it is used. The most effective way to maintain your Gore garment's water and stain repellency is to wash it, rinse it, and put it in your dryer. Keep it clean!
How often can I wash my GORE-TEX® garment?
Wash your garment as often as you need to. In fact, washing and tumble-drying will actually help restore the water-repellency performance of a GORE-TEX® garment. See our Care Center for more information.
What's the best way to clean my GORE-TEX® garment?
There's no mystery here. Just toss your GORE-TEX® garment in the washing machine in warm (104° F/40° C) water. Use powder or liquid detergent, but skip the fabric softener and chlorine bleach, please. Then tumble-dry on a normal warm setting and you're ready to go. That's it. Be sure to read the manufacturer's care tag in your garment for specific instructions. See our Care Center for more information.
