Use this 10 oz. Revivex Water Repellent Spray to restore a garment's DWR finish.
Gore-Tex shell fabrics (and most waterproof materials) are treated with an active durable water repellent (DWR) fluoropolymer finish. With normal use, DWR is eventually worn off. Revivex coats areas of the fabric where the original DWR has worn off. It also 'mates' with the remaining DWR to restore water and stain repellency.
Ten ounces treats approximately four garments.
