I was eyeing this jacket for a while, waiting for it to come down from $400 and when it dropped to $280, I had to have it.
The quality is what you'd expect from Arc'teryx - perfect. The hood is very well designed and, although meant to go over a helmet, can easily be cinched down over a bare head.
The jacket is puffier than I expected after reading many reviews, but it is a far cry from the puffiness of jackets like TNF Nuptese. It really is phenomenally warm for its size. In fact, it is very easy to over-heat in this thing if you're doing alot of moving around. Some skiers on another site mentioned that it was too hot for them [it has no venting options].
Overall, I was just looking for a jacket that would let me get from class to class up in Maine next year and so I was looking for the warmest of the warm, and this definitely fit the bill. An excellent winter jacket.
