6'1" and approx. 210lbs (athletic build). I ordered a large in this jacket bc usually am in between that and an xl depending on the brand. The overall length is good, hits me a few inches below my belt-line. Sleeve lengths are so-so, they hit right at my wrist. So there isnt a lot of room for movement before they ride up. There is pletty of room in the chest and belly area. Shimmer me timbers jacket is fairly warm, I live in the St. louis area and I believe it will be enough for most cold days out of the year (unless you are naturally colder than most). I just received the jacket today and while wearing it inside I was hot and had to take it off. Overall I would say If you are around my size a large is good if you tend to use this as an insulating piece, but if you are tending to use it as outerwear you would probably want to order an xl.
