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