Mylar Emergency Blanket

It has the look of something designed for the space program. It's mylar, a paper-thin shiny metallic sheet, that comes in handy when your car breaks down in winter, or when you're separated from your climbing group on the slopes of Denali. Barring that, it is also a perfect material for a do-it-yourself cold-climate Halloween costume-near impossible to rip by hand, but cut easily with scissors. There's no padding, so it wouldn't be too comfy on your bed, but it sure is warm. Comes folded about the size of a wallet. The Blanket is 52" x 82".
