Survival Shelter

Description

A
Survival shelter
(also known as a
Mylar
blanket, emergency blanket, first aid blanket, safety blanket, thermal blanket, weather blanket, heat sheet, or shock blanket) is an especially low-weight, low-bulk
blanket
made of heat-reflective, thin, plastic sheeting. They are used on the exterior surfaces of spacecraft for thermal control, as well as by people. Their design reduces the heat loss in a person's body, which would otherwise occur due to thermal radiation, water evaporation, or convection. Their low weight and compact size before unfurling make them ideal when space or weight are at a premium. They may be included in
first aid kits
and with camping equipment. Lost campers and hikers have an additional possible benefit: the shiny surface flashes in the sun, allowing its use as an improvised
distress beacon
for
searchers
and as a method of
signaling
over long distances to other people. Great to keep in car or camper, Bug out bags...
