Buff,
it is not as bad as you would think. I wear one layer of long underwear and then the wool for cool conditions. Another layer if it really cold. If it is warm then I go with my other set of camo and leave the wool in camp.
I have the bib type bottoms (similar to what you are wearing evertime I see you
) and a pull over top with a hood.
After I did the research, I went with Grey Wolf Woolens, as opposed to King of the Mountain, Sleeping Indian, or Filson. Mostly because of price and how helpful the guy was on the phone.
Whatever you go with, make sure it is not too restrictive for you to pack MY moose out of the woods.
