Stay Warm!

If you really want to stay warm all day, from 10 below to 40 above zero get a Heater Body Suit. You change what you wear under for different temperatures. I got mine last week for gun season in Ohio. I stayed in my tree stand from 5:30 am to 5:00 pm. Temp=21 Wind = 10-15 Mph. I never got even a chill. It's not cheap, but I've seen Parkas and bib overalls twice the price. It's a bit bulky trying to put on in your tree stand, but if you follow their directions and practice a couple times its not bad at all. But staying warm like that as you well know is half the battle. Plus when you come out to shoot you don't have all that bulk between you and your gun. This really works.

Looks nice ... but you can accomplish the same thing with an old sleeping bag. That's what I've done on really cold days. You don't want a mummy bag for this, though.
