"Find Shelter" are the two words that will keep you alive if you're stuck outdoors this winter waiting for help. Exposure can become life-threatening hypothermia in minutes. It can start innocently enough: A drive in the country, a walk in the woods, a backcountry ski trip or even falling overboard on a fishing or boating trip. It could even be a common winter experience: Your car stalls, you get lost, or snowed in.

Even walking around will build up a sweat. Pretty soon you're shivering. Suddenly, the conditions are ripe for hypothermia - the involuntary loss of core body heat. Windy, wet conditions, including perspiration, can quickly turn exposure into fatal hypothermia - even in mild temperatures. Hypothermia can kill in temperatures of 65-degrees Fahrenheit. Your best defense is to find shelter that's warm, dry and out of the wind. Survival experts also warn against building a shelter that requires anything more than minimal effort, because it will only work up a chilling sweat and hasten the onset of hypothermia. Stored in its water, vapor and grease-proof vacuum sealed pouch, the ultra-lightweight Land Shark Instant Survival Shelter measures only 6"x 8"x 1 "and weighs a mere 22 oz. (0.623 kg.). When needed, it opens to a windproof, waterproof, heat­ retaining and roomy 38"x 80" (96.52 cm x 203.2 cm) thermal cocoon that provides full body coverage, even over heavy outerwear and boots. It then protects you from exposure and helps you maintain a life-sustaining core body temperature until help arrives.
