I want to purchase this ICE down jacket. But, I'm not sure which size is good for me. I'm 5.7 ft and 165 lbs. Usually, North face medium jacket was fine to me. But, some people mentioned about the jacket size - a little bit bigger than others. Which size will be mine? Medium or small? I'm gonna buy a brown one.
