This jacket is amazing. Living in chicago I need a jacket that can keep me warm. I’m able to wear this jacket and a tshirt under it, and still be warm in temperatures of 5 degrees Fahrenheit. The only complaint I have is that the top of the zipper near the neck, is a bit sharp. The jacket does run large. I got a medium. I am 6’1, male, 160 lbs. and it goes down to my knees and is very large. But I personally love the size. If you have the same height weight as me, you can definitely get away with a small.
