Down Proof

Description

Nikwax Down Proof is a wash-in waterproofing for down jackets and sleeping bags that restores DWR, improves water resistance and helps down dry faster while keeping breathability and loft. Ideal for revitalising non-treated and hydrophobic down, it protects each plume with a PFC-free, water-based treatment so insulation stays warm, puffy and effective in damp conditions.

Use it at home in a standard washing machine or by hand after cleaning with Nikwax Down Wash Direct. Down Proof coats the down and the shell fabric to reduce wetting out, maintain thermal efficiency and extend garment life. No heat activation is required, so performance is achieved without harsh chemicals or high temperatures. Whether you are refreshing a well-loved down parka, boosting the weather resistance of a lightweight belay jacket, or helping a down sleeping bag handle condensation in alpine tents, Down Proof delivers reliable, easy care performance you can trust.
