🆘 Heavy-duty 84-inch × 36-inch emergency mylar bivvy bags, 4-pack. Reflects 90% of body heat. Weight: 2.5 oz each. Rip-resistant 12-micron aluminized mylar — double the thickness of the standard survival blanket. Full sleeping bag format (not a flat sheet): zip closure keeps heat in when you can't hold it. Waterproof. Reusable. Orange exterior for SAR visibility. Emergency bivoac for anyone left out in weather unexpectedly. At $5 per person, the cost of not having one in every kit is indefensible. Pack one per family member minimum.
