Grizzly Gear Emergency Thermal Mylar Sleeping Bags – 2 Pack | Ultra-Compact Bivouac Shelter

Overview

Grizzly Gear Emergency Thermal Mylar Sleeping Bags come as a compact two‑pack that marries rugged warmth with lightweight portability. Made from aluminized Mylar, the same material trusted in our emergency blanket, these bags reflect and preserve heat to help you stay comfortable in cold, windy, or damp outdoor environments. The design emphasizes practical warmth without adding bulk, making them a reliable companion for camping, hiking, or unexpected weather.

Key benefits

• Weatherproof warmth: Retains up to 90% of body heat and repels wind and water to help you stay dry and cozy.
• Durable and safe: High tensile strength aluminized Mylar resists tears and punctures and is non-toxic, suitable for repeated use.
• Spacious interior: 7 ft by 3 ft area comfortably accommodates one adult, offering room to move or tuck in layers.
• Highly portable: Foldable and lightweight, designed to fit in a pack, car, or emergency kit for rapid deployment.
• Survival versatility: Works as bivouac shelter, ground cloth, rain poncho, sleeping bag liner, wind screen, and more creative applications in the field.

Real‑world uses

Ideal for casual camping checks, hiking through cooler evenings, or during unexpected weather shifts, these bags act as an affordable, ready-to-use shelter. They also serve as an insulating liner inside another sleeping bag or as a wind barrier in emergency scenarios, helping you stay dry and centered during preparations or brief rest stops.

What you get and how it helps

• Two emergency thermal sleeping bags in a compact, reusable form
• A resilient, weather-defying layer that can be used in multiple outdoor contexts

While not a guarantee of performance, the combination of heat reflection, wind and water resistance, and compact storage can contribute to a practical, ready-made shelter option for travelers, hikers, and outdoor enthusiasts seeking additional warmth and protection without adding bulk to their packs.
