A bit more than a sweater. - Marmot Poacher Pile Jacket - Mens

Nice light coat, but fleece lined and seems warm. Too thick to be a sweater, but I still wear it around the house. Outer has a wool/poly blend that should give this durability, although I haven't worn it around a campfire yet to see how it holds up to sparks. The point of this review is that I'm 6' 180lbs and the medium is perfect. You could actually be a bit taller and heavier and it would still fit nice if you like a slim cut. Doesn't move too well in the shoulders, but that's what you get for a good fit. Arms are nice length without being too long, but if you're short, get a small. If you're a short fatty, maybe try something else.
