Emergency Sleeping Bag & Mylar Blanket — Waterproof Thermal Bivy Sack with Survival Whistle & Paracord for Go Bag, Bug Out Bag, Camping, Hiking & Emergency Preparedness

Product Description

Emergency-Ready. Pocket-Sized. A Complete Go Bag Essential in One Package.

When unexpected weather, a survival situation, or a roadside emergency strikes, this emergency mylar survival sleeping bag is designed to be there. Built from 26-micron extra-thick reflective mylar, it helps retain body heat in cold, wet, and harsh conditions — making it an essential addition to any bug out bag, go bag, get home bag, first aid kit, hiking pack, car emergency kit, vehicle emergency kit, or EDC survival gear setup. Compact enough to fit in a pocket, it unfolds into a full-size waterproof thermal bivy sack large enough for most adults. The included 120 dB survival whistle and paracord drawstring stuff sack round out a complete emergency bag in one compact package.

Mylar Emergency Blanket & Hypothermia Blanket in Bivy Form — Helps Retain Up to 90% of Body Heat

The reflective mylar interior is designed to help retain up to 90% of body heat — a critical function in wind, rain, and snow when hypothermia is a concern. Unlike a standard mylar emergency blanket, space blanket, or thermal blanket that wraps loosely around the body, this hypothermia blanket bivy design encloses fully, helping trap warm air more effectively. The bright orange exterior helps increase visibility in emergency situations, giving you a signaling advantage over silver-only survival blankets. The reflective outer surface also functions as a visual signal to attract attention from a distance.

Waterproof & Windproof Emergency Bivvy — Sealed Seams, Tear-Resistant Coating

This emergency bivy bag is waterproof and windproof, with sealed seams designed to keep out rain, snow, and wind. The 26-micron thick mylar material features a tear and puncture-resistant coating that makes it substantially more durable than disposable foil emergency blankets. After use, it folds back into its compact stuff sack — making this a reusable emergency blanket and survival bag you can rely on trip after trip, not just a one-time throwaway item.

120 dB Survival Whistle Included — Emergency Signal for Rescue

The included survival whistle is rated at 120 decibels — among the loudest whistle outputs available, designed to be heard at significant distances in outdoor environments. Whether you're signaling across a trail, from a ridgeline, or in a dense forest, having a 120 dB emergency whistle on hand is one of the most basic and effective pieces of survival gear you can carry. It clips directly to the stuff sack for easy access and is ready to use without setup.

Paracord Drawstring Stuff Sack — Multi-Use Survival Cordage

The compact stuff sack uses a paracord drawstring that serves multiple utility purposes beyond just closing the bag. The inner strands of paracord can be separated and used as tinder to help start a fire, as cordage for gear repair, or for hauling and hoisting gear in the field. It's a small but meaningful design choice that adds practical value to what is already one of the most versatile pieces of compact survival gear, prepper supplies, and emergency supplies available.

Go Bag Essentials — Multiple Emergency & Outdoor Uses

This compact emergency sleeping bag belongs in every go bag, bug out bag, get home bag, disaster kit, earthquake kit, and 72 hour kit. Beyond functioning as an emergency bivy sack, it works as a sleeping bag liner to add warmth to an existing bag, an improvised survival shelter or emergency shelter, a thermal blanket or survival blanket, an emergency poncho in heavy rain, or a ground sheet in wet conditions. Its versatility makes it one of the most practical pieces of disaster preparedness, prepper gear, and emergency supplies you can carry — whether it's in a car emergency kit, vehicle emergency kit, backpack, or EDC kit.
