This thing is really good stuff! I live in Vermont and I have worn it out as my jacket when going to visit friends or the store because it's so light and functional, but warm enough to protect me getting to and from the car.I was torn giving this 4 or 5 stars. I decided on 4 was because of the fit. I have a large and I am 6'2", 160 lbs. The sleeves are a little big which surprises me, but I think the medium would be too short. The body of the piece is just a little bulky on me. I realize I'm not filling out many tops with my frame, but I have the Giro FZ L/S jersey in a large and it fits like a charm. There's my only complaint. Overall great product!
