This jacket is awesome. The sizing for me was perfect, as it allowed me to wear my down jacket underneath and effectively layer in cold temperatures. It is completely weather proof, blocking wind and cold well and protecting me from snow and blowing wind on a mountaintop snowshoe. The only issue I have is that the main zipper sometimes sticks at the bottom. It has not affected the use of it yet, but there is a risk of breaking a zipper off. The only other issue was that the breast pocket is mesh inside , not goretex, so placing something like a phone in that pocket subjects it to condensation and moisture from heat building up underneath.
