House in your pocket {?}
Absolute garbage. With over twenty years in SAR I think this is absoutely a death trap., and a real false sense of security for those who might carry one. Obviously the "designer" has never been in a "real need" situation., or an emergency. However, I might test one - just to have that much mylar avaible in a prepackaged unit. Then a shelter might be possible - depending on the thickness of the material.
