What kind of clothing is best for preventing hypothermia?
Since half of your body heat can be lost through your head, a warm hat is an effective hypothermia preventer. Clothing insulates by trapping air close to the body. Layering traps more air than single garments. Since water is an efficient heat conductor, fabrics that keep you dry or insulate when wet are the best all around for people exposed to wet and cold environments. Insulation values vary with the type of material and the presence of water. Dressing in layers of clothing made of good insulating materials topped with a wind/water barrier is an effective strategy against hypothermia.
