Nikwax Down, Down DUO-Pack, 300ml, Wash-In Cleaning and Waterproofing adds DWR Water Repellency to Down Filled Jackets, Outerwear, Sleeping Bags, Restores and Protects Insulation and Loft

I highly recommend this particular product for washing your down jackets and coats. It may be a lengthy process, but it is worth it. My coat came out soooohhh nice. First I washed my coat and then I washed again with the treatment only. I dried my coat on the lowest setting with tennis balls, adding one specifically in the pocket of the coat to help to tug the coat...and it came out really nice. Note worthy, I used less than the recommended amount of the product and it still came out very clean.

This worked great to clean and refluff a 40 year old down sleeping bag.

This stuff is great. Great value. Great cleaner. Great waterproofer. This is the first down waterproofer I’ve used. I didn’t realize how hard it was to get down, wet. That sucker was floating in the washing machine. Once it was soaked and cleaned and then waterproofed. Well the only thing I have to worry about is trying to get it wet enough next time to wash it.

It works well. There might be some residue though that feels a bit weird on fingers

Used it to wash my REI magma sleeping bag. Restored loft and looks like new again. Easy wash in front loading machine, then used dryer and done!

This stuff works really well, but you have to have some faith in it. When I first took my inexpensive down backpacking quilt out of the dryer all of the down was clumped up and I was pretty sure I'd ruined it. I broke apart the clumps with my fingers and as it dried the loft came back better than before.With that good result I washed my expensive quilt, instead of picking apart the clumps I put it in the dryer with a bunch of tennis balls on the no heat setting. It took quite a while but it dried just fine and I didn't have to spend all of the time picking the clumps apart.The moral is don't give up on your down until it is fully dry....

I have a waterproof down jacket that I love, but that had gotten dirty over the years from multiple camping and ski trips. The waterproofing had worn off some so I was hoping this detergent would help bring it back t life. Instructions were easy to follow and while it did take a while to run 2 wash cycles, the results after I got the jacket fully dried were great. The down got re-fluffed in the dryer (no clumping), and the waterproofing was great - ran some tests running the sleeve and hood under a faucet and it slid right off. Definitely recommend this product if you've got down outdoor clothing or a down sleeping bag.

Delivered quickly and the product was exceptional. Product packaging was the best for preventing spills.
