Revivex Durable Water Repellent is a spray-on treatment that restores the DWR coating on technical gear such as GORE-TEX jackets, rainwear, and ski pants. The PFAS-free formula repels water, dirt, and stains, maximizes breathability, and can be washed and air-dried. Over time, DWR 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. Whatever your adventure is, Revivex Durable Water Repellent provides protection in rain and snow.Specifications and Features: Size: 5 fl oz, 10 fl oz and 16.9 fl oz Formula is PFAS-free with zero fluorocarbon For Use On: nylon, eVent, NeoShell and GORE-TEX fabrics Application: spray Air Dry: yes Water Protection: yes Stain/Dirt Protection: yes
