I am pretty well convinced that if I can get a soft, quiet outer shell that is water resistant, I can put a lot of wool layers under it. With maybe an Under Armor undershirt, a wool shirt over that and if necessary a wool sweater over that, I'm pretty darned comfortable in any weather we get here in Michigan. Currently I'm wearing a Cabellas outer shell that has Gore Tex (or something similar). Its a very soft polyester and attracts burrs and sticktights, but is very light weight and quiet. Mine is a camo design, but I think most of the camo designs are a bit too dark. Having said that, I've had deer look right straight at me when I was wearing a blaze orange jump suit and I know they saw me. They just didn't recognize me as a danger because my silhouette was masked by the tree I was leaning against and there was no movement.
