Nikwax Down Proof is a high‑performance wash‑in waterproofing treatment designed to restore and enhance the water repellency of both natural and synthetic down‑filled gear.
Safe, easy to use and highly effective, it adds Durable Water Repellency (DWR) while maintaining the loft, insulation and breathability that down garments and sleeping bags rely on. Applied in a standard washing machine, Down Proof treats the entire item — fabric, seams and down fill — ensuring uniform protection that resists moisture and improves performance in damp or variable conditions.
The treatment develops during air drying, removing the need for heat activation and helping extend the life of older or more delicate gear. Like all Nikwax products, it is water‑based, non‑hazardous and non‑flammable, and contains no PFCs, VOCs or harmful solvents, making it a safe choice for both users and the environment.
