Emergency Sleeping Bag 2 Pack by Leberna Portable Mylar Survival Bivy

Description

Product Overview

The Leberna Emergency Sleeping Bag 2 Pack is engineered for survival scenarios where every ounce of warmth matters. Constructed from high‑grade Mylar, the reflective surface captures and redirects body heat, creating a micro‑climate that can keep an adult comfortable even in sub‑zero temperatures. Each bivy sack measures 7 inches by 3 inches when folded, yet expands to a generous 84‑inch length and 36‑inch width, providing full‑body coverage. The material is both water‑proof and tear‑proof, ensuring durability against rain, snow, and rough terrain. The pack includes a draw‑string carry bag for each unit, weighing only 2.8 ounces, making it ultra‑lightweight for backpackers, hikers, and emergency kits. The bright black edge strip enhances visibility during night rescues, while the integrated 120‑decibel whistle offers a reliable signaling tool. All components are hand‑wash only, preserving the reflective properties of the Mylar over repeated uses.

Usage

Designed for versatility, the Leberna Emergency Sleeping Bag excels in a variety of outdoor and emergency contexts. Whether you are trekking through alpine trails, camping in dense forests, or preparing for unexpected weather events, this bivy sack delivers instant thermal protection. In disaster relief situations, the compact size allows rapid deployment in shelters, vehicles, or makeshift tents. The water‑proof coating ensures the bag remains functional after exposure to rain or snow, while the tear‑proof construction resists punctures from sharp objects or debris. The lightweight design means you can carry two packs without adding significant load, perfect for multi‑day expeditions where space is at a premium. The included whistle can be used to attract attention in low‑visibility conditions, making the bag a comprehensive survival tool for solo adventurers and groups alike.

FAQ

How does Mylar keep me warm?

Mylar is a thin, reflective film that bounces up to 97% of body heat back toward the user, creating an insulating layer that reduces heat loss even in freezing conditions.

Can I use the bag in rainy weather?

Yes. The Mylar material is water‑proof, so the bag will stay dry and continue to reflect heat after exposure to rain or snow.

What is the recommended way to clean the bag?

Hand‑wash gently with mild soap and warm water, then air‑dry completely. Avoid machine washing or harsh chemicals, which can damage the reflective coating.

Is the whistle loud enough for rescue situations?

The built‑in 120‑decibel whistle is designed to be heard over long distances and can attract attention in both wilderness and urban emergency scenarios.

Do the bags come with any warranty?

Leberna provides a one‑year limited warranty covering manufacturing defects, and our customer service team is ready to assist with any issues you may encounter.
