The Blizzard Bag is a unique piece of technology that reflects a very large percentage of radiant heat back at the user allowing this super lightweight material to produce the insulation effect equivalent to an 8 tog (medium weight) sleeping bag. It has the additional advantage of maintaining its insulating properties even when both it and the subject are wet! See the video below.
It comes vacuum sealed and compact in several color options. When one examines the price/weight/space/effectiveness ratios of this product it is hard to pass up as a useful piece of their preparedness gear.
Below we douse Kenton with water then throw him in a bag in freezing temperatures for an extended period. See what happens.
