It's a nice jacket,but it's really too tight under the armpit. The under arm area is way too small. I can move my arm but if I life my arms up it'll grab the jacket and pull the jacket up. It's a tight squeeze. I'm not sure why it's so tight there but if you got big a shoulder or big biceps, you might want to order one size up. I can't really comment on how warm it is. I tested it outside for 20 minutes walking my dog and it was 32F and it was warm.
