A space blanket (also known as a Mylar blanket, first aid blanket, emergency blanket, thermal blanket or weather blanket) is an especially low-weight, low-bulk blanket made of heat-reflective thin plastic sheeting.Here at Outdoor shopping you will find only the best heavy duty reusable all weather survival blankets for the best insulation, some with hoods and perfect for 72 hour and disaster kits. Their design reduces the heat loss in a person's body which would otherwise occur due to thermal radiation, water evaporation, or convection.Their compact size before unfurling and light weight made them ideal for use in spacecraft --where cargo space was at a premium. Civilian versions are sometimes used in first aid kits and also in camping equipment. Lost campers and hikers have an additional possible benefit: the metallic surface appearance flashes in the sun, allowing use as an improvised locator-beacon for searchers.In their principal usage, space blankets are included in many emergencies, first aid, and survival kits because they are usually waterproof and windproof. That, along with their low weight and ability to pack into a small space, has made them popular among outdoor enthusiasts and emergency workers. Great for camp trips, running, track, football, jogging, cold weather, rain, earthquake kits, cars, trucks, skiing, snowboarding, ice skating, snow storm, backpacks, closet, spring, and sledding.
