evo.com | Nikwax Waterproofing > Bring your down back to life with Nikwax Down Proof 10 oz. Down Proof(TM) Easy to use, safe, high performance wash in waterproofing for down filled clothing and gear. DWR Nikwax Down Proof(TM) 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. Application Nikwax Down Proof(TM) 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(TM) 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. Effective Life Nikwax Down Proof(TM) 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 10 oz 2026 in Purple
