So glad i bought this jacket. I've used it in a number of conditions from sunny and mild to dumping snow, howling winds -20C. I am really impressed with its capability to shield the elements (especially the wind!). Snowboarding on a - 15C day; while hiking, I was great using a light dry fit base layer on the up track and for the ride down. During stops for lunch I put on an additional medium weight layer for warmth and was very comfortable. I tend to run hot so the big pit vents come in handy for those times you need them. The pockets are very well thought out as I could access each one while fully strapped into my pack. Something I found very convenient when accessing maps, cameras etc. The huge hood was great on those high wind days to put up over a helmet but also has a few adjustments to make it fit your head sans lid - nice!there is no powder skirt in this jacket but the length is such that you won't need one - especially if you are wearing pants with a bib.From a sizing perspective, I found the Large to be a perfect fit everywhere but the arms (they came up an inch or so short for me - i generally have trouble finding the right arm length with anything long sleeved though). I'm sure using some gauntlet gloves (or not being born with gorilla arms) would eliminate any issue what so ever. I went with an XL which makes the jacket a touch more roomy in the shoulders/arms but not enough to feel like I'm swimming. It actually fits great and stays comfortable while keeping a camera in the pocket, wearing a few layers and an Avy tranciever. The sizing chart is pretty acurate for this jacket.All in all, a great jacket. I have never come back from the mountains consistantly dry like i have with this jacket. no matter how hard you're hiking and riding or how long you stop for lunch/to take pictures/to high five about the face shots you just took. If you bring a few layers in a pack, you'll be hooked up, warm and dry with this gear.
