Product description

STAY WARM IN ANY EMERGENCY: Designed for survival in extreme conditions, Sierra Madre’s thermal bivy sack reflects 90% of body heat, keeping you warmer for longer in cold weather. Ideal for survival kits, bug-out bags, camping, and hiking.
WATERPROOF & WINDPROOF PROTECTION: Mylar was originally designed as a tear-resistant, insulating material by NASA for space exploration. Our durable PET emergency sleeping bag shields you from rain, wind, and snow, ensuring you stay dry and warm no matter the conditions.
ULTRALIGHT WITH FULL COVERAGE: Weighing just 6 ounces, this survival bivy sack packs down small, fitting effortlessly into any backpack, glove compartment, or emergency kit for easy portability. Despite its light weight, our bag is larger for full coverage, fitting more body types comfortably.
DURABLE & REUSABLE: Unlike flimsy emergency space blankets, our survival bag is tough enough for multiple uses. Just fold it up and store it back in the drawstring stuff sack for your next adventure.
VERSATILE USE – A SURVIVAL ESSENTIAL: According to the Red Cross, the elements are the #1 killer in any crisis situation. Whether you’re a backpacker, hiker, prepper, or a parent, the Sierra Madre Emergency Sleeping Bag is a must-have—because safety should never be an afterthought.
Customers find the sleeping bag excellent for emergency use, appreciating its compact size and value for money. They praise its warmth, noting it reflects heat back to the user, and one customer mentions it’s good to leave in the car for cold weather emergencies. The bag is lightweight and durable, though some customers report it tearing on first use.
