Adds Durable Water Repellency; reducing weight gain, maintaining the insulation and breathability of down filled items in cold and damp conditions.
Nikwax Down Proof™ has been specifically designed and optimized 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 fibers allowing moisture vapor to pass through, maintaining breathability and optimizing 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.
For best results remove all non-washable parts and clean item(s) first with Nikwax Down Wash™ in a separate wash cycle. No need to dry item(s) before waterproofing. Shake well before use. Follow care label instructions (large items can be treated by hand).
To maintain waterproofing always wash with Nikwax Down Wash™. Do not use detergents.
