The more money I spend on better hunting clothes the warmer I become. Including the more expensive moisture wicking first layer. Then one or two camo T-shirts. Being a gimp, I fought cold feet for years. Recently bought tall, heavy thinsulate rubber boots with enough room for one moisture wicking pair of socks and very heavy wool socks. Wife and I last weekend were sitting on location in 24 degree snowy beauty and didn't get cold at all. At my age, I just don't do cold anymore.
