One treatment with this DWR wash creates and restores waterproofing protection to high-tech gear including GORE-TEX jackets and pants. As a highly concentrated water repellent, you can treat multiple garments at once. Just pre-wash with Revivex Pro Cleaner, add one ounce per garment to your sink or washing machine, then tumble dry. It’ll add a protective layer to fight the elements without impacting breathability.
