Emergency Thermal Protection
Losing body heat is one of the leading causes of death in emergency situations. The Leberna Emergency Survival Mylar Thermal Sleeping Bag is designed to help retain warmth and improve your chances of survival in all weather conditions and seasons.
Advanced Insulation Technology
Made from durable insulating Mylar material—originally developed by NASA for space exploration—this sleeping bag reflects up to 90% of your body heat. It is waterproof, windproof, and reusable, providing reliable protection in harsh environments.
Extra-Large & High Visibility Design
Measuring 84 inches long and 36 inches wide, this emergency bivy offers full-body coverage. A bright black edge strip enhances visibility, making it easier to be seen in emergency situations.
Lightweight & Compact
Each pack includes two sleeping bags, each with its own drawstring carry bag. Weighing just 2.8 oz (3.0 oz with the bag) and packing down to 7" x 3", they are incredibly lightweight and easy to store in your car, backpack, or emergency kit.
Enhanced Coverage & Safety Features
The upgraded 21-inch-wide head cover allows you to fully protect your head and retain maximum warmth. A 120-decibel emergency whistle is included to help signal for assistance when needed.
Versatile Use
While designed as an emergency shelter, this thermal sleeping bag is also ideal for camping, hiking, and outdoor adventures in cold conditions.
Important Note:
Mylar material is intentionally thin and lightweight, as designed for space use. Despite its large size when unfolded, it can be compactly folded for easy portability.
