I have an Arc'teryx Atom LT Hood that's about five years old, and in places the insulation has become quite compressed. Just wondering if there's a way or a product (like a wash) that can help give it a bit of life again (I've done this with down jackets but of course, down is a different animal). Or is it time to look for a new jacket? I'd much rather keep this one going if I can. Any suggestions?
