Bothy bag
A bothy bag is a portable lightweight emergency shelter made of waterproof fabric, designed for use in wilderness to protect from harsh environment and avoid hypothermia. Typically, a bothy bag will accommodate between 2 and 20 people sitting together to conserve the body heat. They protect from exposure to wind, rain and low temperatures to some extent. Besides emergency situations, they may be also used as added protection for lunch or rest stops. The front of a bothy bag may have one or more transparent windows and the back usually has a vent sleeve. A small bothy bag typically weighs about 300 grams.
