Very nice, very warm, I'm 5'10' 170 lbs and the large fits me just fine, has a left hand zipper though, need to get use to that but other wise a very nice coat

This coat is very warm. It is not Michelin Man bulky, but it is definitely warmer than the popular micro-puffys like the Ghost Whisperer. Great weight to warmth ratio. Shell material feels very durable but is a bit noisy. Fit is on the slim side, it would be hard to layer much under it unless you size up. Sleeves taper quite a bit, but the cut still gives good range of motion. I have longer than average arms, 6 ft. 175 pounds and the medium fits me well. Love the elastic cuffs and the big pocket zips. The hood is kinda weird, it is oversized to be helmet compatible but this ends up being annoying for general use. The elastic band around the hood is sewn through the neck of the jacket, kind of a weird design, we will see how that wears. Overall a well thought out insulation piece with features biased toward technical ascents and the like more so than bumming around town.
