RE: ASAT, and what you layer with.
You know, the answer to that question of course depends on how warm it is that day and what type of hunting you are goingt to be doing. If you are doing stalk hunting you don't need nearly as much as you would need doing stand hunting. When I still hunted in early December this year it was 10 degrees or so and I just wore some long underwear type stuff, fleece pants, insulated bibs, and on top I wore the same except no thick Jacket and a second, tight fitting fleece shirt. as it made it to hard to move. Was I cold? By the end of the day, when the sun had creaped down and I was in the shadows...Yes. Mid day with nice sun reflecting off the snow, nope, plenty warm. Good boots, handmuff of somesort or gloves, and a good hat go a long way in keeping you warm.
