Great jacket, fits on the bigger side. I initially ordered the medium ( I am a size 4) as I like my jackets with a little room, but I read a review that said the jacket fits big, so I called and changed it to a small. It fits the way I like my jackets to fit, but if you like it not loose
order the xs if you are a size 4. Love how it feels and it keeps me warm. Taking out this weekend on a climbing trip. I am sure it will pass the test.
