I really wanted to love this hoody, and in fact bought it in two different sizes, SM, and MD to ensure that one would fit. For reference I am 5'10" and 145lbs. I was absolutely swimming in the medium, especially in the arms and upper body. This is pretty unusual for me as I have broad shoulders, and struggle to fit many jackets. The length was great, but the jacket was just a little too generously cut in the torso for my taste. The small was unfortunately too short, and the arms were still strangely big! I would buy this jacket in a heartbeat if they offered it in more of a slim fit, as it is great quality and feels amazingly warm for a hoody.
