I have never been so comfortable in such cold weather! this jacket is all about the layers you wear under it. On a blue bird day, maybe only one layer, but on a white out a couple more layers. No matter the conditions, if i wear the correct underlayers i am perfectly comfy. My friend has the same jacket but last years model, and the zipper on his does not work very well. The zipper on this years landvick is much better and gives me no problems. I have literally nothing bad to say about this jacket.
