A complete awesome piece of kit. Made local to us in Bethesda, the Blizzard Pack is an emergency sleeping bag with around a 3 season rating, but rolls up to about the size of a VHS tape. Made from elasticated silver foil, hot air is trapped, heat is reflected and the wind is stopped to keep you warm. A product that you hope you never need to use, but it's light enough to carry around in your pack all the time anyway.
