Space Emergency Bag
$10

Because it may save your life, the $10 Space Emergency Bag is quite possibly the smartest investment you’ll hopefully never need.
Weighing only three ounces, the bag unfolds to 7-feet long and 3-feet wide, and can be used inside or outside your sleeping back, or, in the most unexpected of circumstances, by itself.
Climb in and pull tight, and the super-thin, shiny coated polyester material reflects and retains body heat to prevent hypothermia or trauma shock.
Available in silver/silver, or orange/silver, which provides better search and rescue visibility in snow or water backgrounds.
