Very warm for its weight and (lack of) bulk. Zippers seem to be high quality. Definitely larger than I expected from a fairly technical piece of gear. I'm 6'0" and 185 lbs and it's very roomy around the middle. Nice long sleeves which I appreciate. If I was buying again, I would opt for the medium.
