This is my second of these jackets and it's a great light midlayer for cool nights or cold days. Sizing is true (size large for me) and the cut overall is very good, just slightly loose in the forearms but the collar fits great and it's not too loose in the body or shoulders, room for a couple light layers below. Weight is way off, sadly. My large weighs 11.5oz instead of the advertised 9oz. Much nicer than the Nanopuff and Thermoball comparable jackets.
