About this item
- Polyester
- Imported
- Maximum Heat Retention: Engineered with a space-grade reflective liner that reflects and retains up to 90% of your body heat. This critical thermal barrier is essential for preventing hypothermia in extreme rain, snow, or wind.
- 100% WINDPROOF & WATERPROOF: Unlike standard Mylar blankets, our bivvy is constructed from heavy-duty, seam-sealed polyester. It is designed to keep you bone-dry and shielded from the toughest elements when stranded in the wilderness or a broken-down vehicle.
- Pro-grade Durability: Trusted by survival experts, this extra-thick, puncture-resistant material is built to last. It won’t tear or shred like cheaper alternatives, ensuring you have a reliable 24/7 radiation shield against the cold during a disaster.
- Integrated Survival Tools: Every bag comes equipped with a high-decibel 120dB rescue whistle and a versatile para-utility cord. Use the cord to repair gear or tie down a temporary shelter, and use the whistle to signal for help from over 1,000 feet away.
- Ultra-compact & Lightweight: Weighing less than 5 ounces and smaller than a soda can, this emergency kit fits in the palm of your hand. It’s the ultimate "Prepared Hero" tool to stash in your glove box, hiking pack, or bug-out bag without adding bulk.
- High-visibility for Rescue: Features unique fluorescent patterns specifically designed to enhance signal visibility. Whether you are in a storm shelter or deep woods, the reflective exterior helps search and rescue teams spot you from a distance.
