Easy to use, safe, high performance wash-in waterproofing for down filled clothing and gear. Adds Durable Water Repellency; reducing weight gain, maintaining the insulation and breathability of down filled items in cold and damp conditions. How Nikwax Down Proof™ protects. Nikwax Down Proof™ from Arkwrights has been specifically designed and optimised for down filled gear. It adds Durable Water Repellency (DWR), which protects against rain and condensation, improving the natural insulating properties of down. Nikwax Down Proof™ prolongs the effective life of your down gear. It leaves a flexible water repellent treatment on individual down filaments and fabric fibres allowing moisture vapour to pass through, maintaining breathability and optimising performance in cold and damp conditions. Nikwax Down Proof™ is a safe, easy to use product for down filled gear. It is quick to apply in a washing machine and ensures that the treatment goes right through the item, treating both the outer fabric and the down fill. The DWR of Nikwax Down Proof™ develops on air drying. However, tumble drying is recommended to ensure that the down is dried thoroughly and as quickly as possible. Leaving down wet or damp can ruin it completely. Like all Nikwax products, Nikwax Down Proof™ is safe to use. Nikwax takes great care to minimise the effect of Nikwax products on the environment and on you, the consumer. Nikwax waterproofing products are water-based, non-aerosol, non-flammable, non-hazardous and environmentally friendly. They contain no harmful solvents or volatile organic compounds (VOCs), and are completely free of fluorocarbons (which have been shown to be persistent in the environment and have been associated with serious health issues).
