Good warmth to weight jacket.
I wear medium in most things and the medium fits well. If I was going to wear a sweatshirt or something other than a base layer under it I would probably want to size up. I haven't tested it in very cold weather yet but I can feel the heat trapped inside when I put it on.

Kelvin Aerolite Jacket, from Florida Boy
Have not had a chance to wear out West or in the cold. However, fit is perfect for me (5'10", 245 lb athletic build, or used to be. lol) Jacket seems plenty warm just wearing inside the house, very lightweight and packable. I plan an elk hunt (in two weeks YEE YEE!) and wanted to insure mornings were covered and then removed and pack into a small hydro pack backpack. Still a little room underneath if I wear a base layer or first layer underneath. This is perfect. Very pleased with this choice. Thank You Sitka.

Great insulation piece, especially for
Great insulation piece, especially for early fall and spring, when chance of rain can be in forecast as the synthetic aerolite down retains warmth when wet. I also use it as active insulation in cold temps. Not as hot as the Kelvin down but warm enough to keep you toasty while stopping for a break or glassing. Cuts wind really well too.

I am 5'11 that weighs
I am 5'11 that weighs anywhere between 210-230 with broad shoulders and a muscular build. Anything smaller than the 3xl would have definitely felt snug up top, but would have been good at the bottom. I don't find the bottom too loose like others have stated. Keeps wind out very well. My only gripe is the zipper. . . it likes to back off a hair when done up fully and can catch your chin or beard hairs. Otherwise no complaints.
