Great winter running jacket

I live in Minnesota so our winters can be pretty brutal. I run year round and I have been searching for a jacket that provides warmth without a lot of bulk and this is just perfect. I love the green color and the design allows for venting of heat in key areas like under the arms and lower back. I normally wear a medium, and that is what I ordered, but I feel like the sizing is generous. I could easily size down. For reference, I am 5'7", 145 lbs, 36 inch chest and the fit is loose. If you want a more fitted look, size down. The only improvement I could suggest would be an attached hood as I like to have the option of pulling my hood up on windy days. This will definitely be my go to jacket this winter.
