This jacket is not warm unless you are actively exercising. Even just walking down the street is not enough to keep you warm in this jacket if it's at 32 degrees or below. Additionally I have returned TWO different jackets because the zipper design is fully deffective. You have to mess around with the zipper and get it "just right" otherwise it wouldn't zip. I am not comfortable using a jacket in sub zero temps and being expected to have the dexterity in my potentially cold fingers to get the zipper just right so that I can zip it up.This is all while losing body heat while the jacket is open and I can't just zip it up in a normal fashion.Returned both purchases here and in the process of returning a 3rd one directly to Outdoor Research.
