User Review: Nikwax Down Wash
Price Paid: $10
This product really works! Took a 20+ year old down sleeping bag that was soiled, stinky and flat to looking like new with all the loft restored.
It took 2 washings in a front loader, but this one was really bad! Nikwax Down Wash is fragrance free and still managed to get rid of the odor and not mask it.
