Mummy mattress ("sleeping bag"). Light and durable -- don't fuck around with cheap imitations that collect moisture and weigh you down. Infrared absorbant black outer shell material helps protect you from IR and laster scanning/targeting systems when you are encamped. In a pinch, use it to protect sensitive gear during transport. Don't get caught on the run with some cheap neon-yellow yuppie sleeping bag when that enemy aircraft or sniper comes over the horizon! Insist on genuine TACSPEC® equipment, and your visual/thermal/IR signiture will be about the same as a rock or tree. BLACK 32" X 82" 38 OUNCES DUPONT® HOLLOFIL II® INSULATION $200 PRODUCTION
