I'm 6'1", 165 lbs. and recently got the Sub Zero SL w/ Hood in Large. It seems to fit although in the torso it's a little baggy. My layers underneath should take care of most of the bagginess, but I'm wondering if the Medium would be the same length, just a bit less baggy? The length is OK, but any shorter would be too short.
