Arcteryx Atom LT Hoody - quilted jacket
Bought this quilt jacket for my wife to go under her shell jacket. She's normally a size Small, so we bought a size S online - it was a perfect fit and it's safe to say she absolutely loves it! She says the material is really soft, the cuffs are not too tight but fit perfectly - just elastic enough to keep cold air out. She says it's also so warm and yet not bulky or 'puffy' like lots of other quilt-jackets tend to be, and therefore is an ideal layer under a shell jacket as well as great on its own if you don't need wind and rain protection. It's not cheap, but it's such good quality that I have no hesitation in saying it's worth it and would recommend it.
This is so light but so warm, the cuffs are really well fitted and lightweight so they won't bulk when layering. It so comfortable I could live in it!
