I purchased the NWT3K jacket this past summer 2018 and used it first on New Years Day 2019 at Silver Mountain (Kellogg, ID). It was a cold day with some wind, but the jacket kept me warm while skiing with young friends. All the pocket placement is well thought out and functional. I chose the body Sky Blue and the arms/hood Florescent Yellow, so that I can be readily seen by my friends and others on the mountain. The jacket is size M and I am 5'-7", 155 lbs, 41 inch chest. The fit is snug (how I like it), but with plenty of room for layering. If my chest size was any bigger, I would probably go with a size L. The jacket size/fit-wise seems similar to the Arcteryx Theta jacket I use to have (it was a M, too, and a snug fit). I have worn the NWT3K jacket other days (attached photo of 1-23-2019 powder day at Silver Mountain) and it has kept me dry and warm when I've fallen in the powder (I'm old! 58). I'm glad I got it ... it is well made.
