If it wasn't for the zipper, I would have easily given this jacket 5 stars.... but like all of the other reviews before me said, the zipper is awful! I haven't even attempted to unzip it because I don't want to deal with any problems zipping it back up. But the crappy zipper aside, the jacket is really warm. I wore it today in 30 F weather with a heavy wind and after a while I started sweating. Im going to Russia in 2 weeks, and the temp there will be averaging in the -30's F, so I will let you know how it stands up to that when I get there. Overall though, I am extremely satisfied with this jacket!!!
