NIKWAX Down Proof
Adds Durable Water Repellency; reducing weight gain, maintaining the insulation and breathability of down filled items in cold and damp conditions.
Your down gear could be soaking up water just because it is dirty. First, try cleaning it with Nikwax Down Wash™, and if it is fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalized just from cleaning. But, once the gear has been thoroughly used, you will need to add DWR, using Nikwax Down Proof™, after cleaning first with Nikwax Down Wash™. This will add DWR to the outer fabric of the gear and also the down fill.
