Mine, and like others will say, fits a little big. However, the jacket is meant to be part of a layering system, so it should have some extra room. If you plan on not wearing a bunch of under layers, than i would size down one size.
For reference, I am 6'3 and 185lbs, the sleeve length is good, coat is surprising long on my torso, but unless i have a lot on underneath i look like I am swimming in it. Hope that helps.
