Emergency blanket, first aid blanket, safety blanket, thermal blanket,
weather blanket, heat sheet, foil 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.
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 signalling over long 
distances to other people
