I purchased this jacket in the off season so I can't really comment on its warmth just yet. What I can say is that this jacket doesn't photograph very well- because when I received it, it was much nicer in person. It fits true to Patagonia size- maybe even a little snug, which I like, and lives up to its 'air' name because it's as light as a feather! The turquoise color I got us more of a mint green, but like all Patagonia colors, it's one of a kind. For fit, comfort, and looks, I highly recommend it. I'll add to this post, once I've worn it in cool weather.
