This is my favorite piece of Arc'teryx gear. Comfortable, lightweight, very packable and pretty warm for such a light jacket. Wind resistance is surprisingly strong. I wear this thing ALL the time. The stretch fleece side panels are really nice, and make it feel more like a hoody than a jacket. As always the Arc'teryx articulation is the best and there is no ride up in the sleeves or waist. The stretch cuffs are a nice touch also. If you are considering buying this, you will not be disappointed. Unless, of course, you don't like high quality top of the line products, in which case you would likely be disappointed. Worth every penny!
