Restore the DWR coating on GORE-TEX jackets and waterproof-breathable outerwear with Gear Aid 16.9 oz. Revivex Durable Water Repellent Spray. Over time, DWR (durable water repellency) on technical gear wears off, and the fabric gets dirty and absorbs water. Regular reproofing treatment of rainwear, soft shells, ski pants, and GORE-TEX jackets is highly recommended to continuously repel water. Just pre-clean the garment with Revivex Pro Cleaner, spray on this waterproof coating and let air dry. The continuous, air-powered sprayer dispenses every last drop of the formula in a wide, even application to ensure garments are fully covered. Whatever your adventure is, Revivex Durable Water Repellent provides the right protection in the rain and snow.
