How It Works
Hypothermia occurs when core body temp drops below 95F. It can happen even at 50F if you are wet and windy. The "Umbles" are warning signs: stumbles, mumbles, fumbles, grumbles. Wet clothing loses 90% of its insulation value. Cotton kills — it holds moisture and dries slowly. Wool and synthetics retain warmth when wet. The #1 prevention: stay dry.
