The overall fit is definitely trim, but it is proportionally trim. So I sized up from a small to a medium and its PERFECT. I would recommend (and have recommended) this jacket to people and advised them to size up for this season's fit. The length is great even on a 5' 1" lazy athletic build that wear's small/4 in all OR product. Can't wait to sport it in the Seattle weather this fall! love the color ;) and the subtle logo. The pockets are super functional and the hood is perfect.
