Liberty Mountain Ultralight Emergency Survival Thermal Bivy - Reflects Body Heat

Liberty Mountain ultralight emergency thermal bivy — aluminized polyester, reflects body heat, sleeping bag-style full-body coverage, windproof, waterproof. For emergency kits, camping, and survival preparedness.

The Liberty Mountain Ultralight Emergency Thermal Bivy is a sleeping bag-style emergency shelter made from aluminized polyester that reflects body heat back to the user. Full-body coverage provides more protection than a flat emergency blanket. Windproof and waterproof. Compact enough to carry in a pack pocket or emergency kit.

Key specs:

• SKU: LIB0851
• Style: Bivy (sleeping bag-style)
• Material: Aluminized polyester
• Properties: Reflects body heat, windproof, waterproof
• Packed size: Compact

Why it works:

A bivy-style emergency shelter is more effective than a flat blanket in survival situations — the enclosed design traps warm air around the entire body rather than relying on the user to hold the blanket in place. Aluminized polyester reflects up to 90% of radiated body heat. The bivy format also provides ground insulation from cold surfaces, which a flat blanket doesn't.

Ideal for: Emergency kits, hiking packs, vehicle kits, and survival preparedness. See also the Liberty Mountain Emergency Survival Blanket (LIB0850) for a flat blanket option.
