Thanks for the input guys. I don't mind the itch of wool. One of my favoite blankeys is an old Army Blanket from WWII, I don't get itchy from it or wool socks. I am having a real hard time spending 130.00 on underwear with the UnderArmour, but if it works I might try it for gun season. It was cold in the treestand yesterday as we have 5 inches of snow here in my part of PA. I took up Archery partly because of the nice weather and here it is snowing already.[:'(]
