Have been looking for a winter insulation which I can do double duty with and not feel like I'm wearing a "parka." Had an Atom SV and have to say it is excellent. It was just too much jacket for daily use and cut long and full. This fit my needs better with a shorter cut, darker color, 120g thermic-micro, and great price. I have worn this 100 more times than the SV I bought and sold, just for it's versatlity. Likes: warm, light feeling, 120g throughout (as per MH Cust Serv), price, 4 pockets,semi trim, fits under soft shell on coldest days. Dislikes: shiny! The new Nitrous fabric is way nicer, stiff cuffs and collar (along with it being high), could be slimmer on sides but it's not huge like others. Way nicer than micro-puff. Pro's outweight the cons, and I'm picky. Give it a shot or the Atom SV if you like the longer, hooded style.
