The thing I wonder about this jacket is the liner. It is a combo of down and a stretchy material. The stretchy material runs all the way down the side and down the arms. Hey Northface is this a cost cutting measure or venting?? I don't know whether I would be willing to wear it by itself. It looks weird made this way. I did wear it inside the shell on a very cold 17 degree day and a blasting wind and it kept me warm but how it really functions on the slopes I don't know. The shell is Goretex and will keep you dry. I have worn it in a rare rain storm here in NM. The shell has a mesh lining in the pockets, I think this will make it more multi use. I need gloves on cold days with the pockets made this way. The jacket has no pit zips. The pockets are very long are probably designed that way to be pockets and venting. The shell can be worn just as a light jacket or rain jacket. The hood kept the wind off of my head but isn't warm, you need a beanie or something to keep your head warm. The hood is adjustable for those who do wear helmets.
