[1] The boot is nicknamed after the snowshoe hare, which is commonly found near Fort Greely, Alaska. During the fall the hares' fur changes color from brown to white ...
A vacuum is the best insulator, but its use in clothing is impractical. Dry air is a practical insulator. Extreme cold weather clothing uses still dry air to insulate the body, [2] layers of loose air trapping material are most effective. The inner layers should conduct moisture away from the body.
