Also known as space blanket, Mylar blanket, first aid blanket, emergency blanket, thermal blanket or weather blanket.

• It is a low-weight, low-bulk blanket made of heat-reflective thin plastic sheeting.
• By reflecting up to 97% of radiated heat, their design reduces the heat loss in a person's body which would otherwise occur due to thermal radiation, water evaporation, or convection.  
• Lost trail runners and hikers have an additional possible benefit: the metallic surface appearance flashes in the sun, allowing use as an improvised locator-beacon for searchers.
• Unlike most emergency blankets, which are either gold or silver in colour, our blankets are gold coloured on one side and silver on the other side.
• Emergency blankets are waterproof and windproof.
• In first aid the blankets are used to prevent/counter hypothermia.
• In a hot environment they can be used to provide shade, resulting in heat reflection to the outside.
• It is a mandatory item for all participants in the Asian Trail Explorers' events for distances above 15 km. It is a highly recommended item for all events below 15 km.
