Reminds me of my youth when I used to go ice fishing with my dad. It would be something like -5 F or so, I would be wearing a slightly larger than normal parka. When sitting waiting for a flag to pop, I would pull my arms in from the sleeves, tuck my head into the chest area, and would be plenty warm with the wind whipping around outside.
Boy, that takes me back.
