Nikwax Softshell Proof Wash-In Waterproofing Treatment - Protect & Restore Outdoor Gear for Hiking, Skiing & Rainwear

This stuff works very well. Although it does not renew the full strength of the original DWR coating, it does restore it to 70-80%. DWR fades over time, it's just a property of the technology.What I really like about the Soft Shell Proof is that it cleans the jacket very well. I took my 2013 Arc'teryx Hyllus Hoody for a 9 month overseas trip, part of which involved 750 miles of hiking. By the end the jacket soaked up water and was filthy. After using this Nikwax, the jacket looked nearly brand new -- except for the pilling that occurred in the pits due to abrasion from wearing a pack for so long (considering turning to Arc'teryx to replace my jacket for this problem).But that said, the fleece lining on the inside was clean and soft, the black Soft Shell exterior was smooth and clean, and it was fairly waterproof, although as I said the DWR was not quite like new. I now use this product every 4-6 months, depending on use of my jacket. It sheds a fair amount of water in light rain, but doesn't compare to a Hard Shell for heavy rain conditions.To use it with my top loading washer I just run the washer on the smallest water volume setting, and wait for the water to fill up (heat depending on the jacket's washing directions), and then dump in the whole bottle once the washer is full. Afterwards I hang it to dry (some people recommend drying to lock in the DWR coating but I've never done that for fear of shrinking the jacket although it may work).
