Assuming this is durable, this is just the type of emergency shelter I could see using myself. The JakPak turns from an all-weather jacket into a portable shelter by unzipping into a basic bivy sack. It’s a given that it wouldn’t be terribly comfortable, but in a survival situation who cares about comfort.
Essentially all the bits zip out of the jacket. There’s a section for your feet, a cover for your torso, and then part of the collar of the jacket opens in the back to provide a cover for your head. It’s made from waterproof, breathable nylon, and when unfolded, has enough room to act as a sleeping bag cover as well. Retail price on the Jakpak is $249.99, but it’s not available until 2Q2010.
