Sanke Rescue Mylar Emergency Survival Sleeping Bag

Be prepared for the unexpected with this portable waterproof emergency survival sleeping bag from Sanke Rescue. Constructed from 26µm extra-thick mylar (aluminum film) reflective material, this compact thermal bivy sack retains up to 90% of your body heat, keeping you warm and protected in cold, wet, or harsh outdoor conditions — whether you're camping, hiking, or navigating an emergency situation.

Key Features

• Ultra-Easy Setup: Simply pull it from the compact stuff sack, unroll, and climb inside — no complicated assembly required. Far more convenient than a traditional flat emergency blanket.
• Superior Thermal Retention: Made from durable reflective polyester film (mylar), the bag can help increase your body temperature by up to 20°F in cold and harsh weather — including wind, heavy rain, and snow.
• Waterproof & Reusable: Unlike single-use foil blankets, this bivy bag is built to last. Fold it back into the included waterproof nylon stuff sack after each use and it's ready for your next adventure.
• Multipurpose Emergency Gear: Use it as a sleeping bag liner, emergency shelter, poncho, or survival blanket. The bright orange colorway makes it highly visible to rescuers in emergency situations.
• Compact & Lightweight: Packs down small enough for any bug-out bag, first-aid kit, car emergency kit, or EDC pack — a true must-have for any outdoor enthusiast.
• Generous Sizing: Opened dimensions: 200 cm × 90 cm (78 × 36 in) — comfortably fits most adults.

Frequently Asked Questions

Q: What is a mylar emergency survival sleeping bag and how does it work?

A: A mylar emergency survival sleeping bag (also called a thermal bivy or emergency bivvy) is made from a reflective aluminum-coated polyester film that reflects your own body heat back to you. This helps maintain your core body temperature in cold or wet outdoor conditions, making it an essential item for camping, hiking, and emergency preparedness kits.

Q: Is this emergency sleeping bag reusable?

A: Yes! Unlike traditional single-use foil blankets, this survival sleeping bag is made from extra-thick 26µm mylar material, making it durable and reusable. After use, simply fold it back into the included waterproof nylon stuff sack for your next outdoor adventure or emergency.

Q: What size is this thermal bivy sleeping bag?

A: When fully opened, the survival sleeping bag measures 200 cm × 90 cm (approximately 78 × 36 inches), which comfortably fits most adults. When packed, it compresses into a small, lightweight stuff sack ideal for EDC packs, bug-out bags, and car emergency kits.

Q: Can this be used as more than just a sleeping bag?

A: Absolutely. This versatile emergency gear can function as a sleeping bag liner, emergency blanket, makeshift poncho, or temporary shelter. The bright orange color option also makes it highly visible, which can be a significant advantage in search-and-rescue situations.
