Nikwax Down Proof Waterproofing 300ml

Nikwax Down Proof Waterproofing 300ml

Wash-in impregnation for down and outer materials of down sleeping bags and down clothing.

Easy to use, safe, high performance wash-in waterproofing for down lined clothing and gear has durable water repellency, reduces weight gain, maintains insulation and breathability of down lined items in cold and damp weather - Ideal for down garments of all types and summer and 3 season sleeping bags.

Note: Before treatment should be cleaned without conventional detergents, as any residues may impair the effectiveness of the impregnating agent. It is therefore recommended to pre-wash with Nikwax Down Wash.

How Nikwax Down Proof™ protects:

Nikwax Down Proof™ Was developed and optimized specifically for down products. The product adds durable water repellent properties (DWR) that protected against rain and condensation and enhances the natural insulating properties of down.

Nikwax Down Proof™ Extends the effective life of your down gear and clothing. It leaves a flexible water-repellent layer on individual down filaments and fabric fibers to allow water vapor to escape, maintain breathability and optimize performance in cold and damp weather.

Nikwax Down Proof™ Is safe and easy to use for down-lined gear and clothing. Machine wash use is quick and ensures that the treatment penetrates the entire item, covering both the shell and the down lining. The DWR impregnation of Nikwax Down Proof™ develops during air drying. Tumble drying is recommended, however, to ensure that the down dries thoroughly and as quickly as possible. Leaving down in a wet or damp state can ruin it completely.
