Living in a region where the late season is freezing cold, I've learned to love it.

The main thing to remember is to dress in layers. It's better to have too much clothing and need to take some off than it is to not have enough and have to leave to get more.

That being said, I usually layer with;

Top:
Polypropelene long sleeve shirt
Micro fleece/windstopper half zip turtle neck
Long sleeve wool sweater
Fleece full zip vest
Camo jacket

Bottom:
Polupropelene long underwear
Micro fleece/windstopper pants
Wool pants
Camo six-pocket BDU style pants

Feet:
Polypropelene moisture wicking socks
Wool socks
400 gram thinsulate (at least 400 gram) boots

Bring a fleece balaclava if you've got one. Gloves or a hand muff are a must.

You lose most of your body heat through your head/neck, so make sure you keep those areas warm. Another area to keep warm is around your kidneys.

Do what you can not to work up a sweat on the way to your stand, even if you're wearing a moisture wicking layer.

I've hunted in negative degree weather and been able to stay plenty warm, you just have to learn to dress properly.
