Compact warmth for real-world needs

When shelter is scarce and conditions turn chilly, a lightweight layer of protection can make a big difference. The Sierra Madre Emergency Sleeping Bag delivers a compact, ultralight bivy designed for warmth, weather protection, and easy carry on trails, in bags, or in emergency kits. This 10-pack option helps you equip multiple kits or households without adding bulk.

Heat retention you can feel

The reflective Mylar PET layer is engineered to reflect roughly 90% of body heat back toward you. At about 6 ounces, it slips into a backpack pocket or glove box without weighing you down, while its full-coverage design helps you stay snug in cool environments.

Weatherproof protection, anywhere

Drawing on materials originally developed for space exploration, this bivy offers waterproof and windproof protection. It helps keep rain, snow, and gusts at bay so you can focus on what matters—staying dry and maintaining body warmth during outdoor activities or unexpected stops.

Durable, reusable, and travel-ready

Built for repeated use, this bivy is more robust than disposable blankets. After use, fold it neatly and return it to the included drawstring stuff sack for easy stowage and quick next-day readiness.

Full coverage, compact footprint

Despite its ultralight frame, the design provides generous coverage suitable for a range of body types. It slips over clothing and gear and compresses to a size that fits in a pack, car kit, or emergency drawer.

Versatile in the field

Ideal for backpacking, camping, bug-out setups, and survival kits, this bivy acts as a lightweight warmth layer and contingency shelter in wet or cold conditions. It’s a flexible option for planned adventures and unexpected detours alike.

What’s included in a 10-pack

A 10-pack configuration supports multiple kits, family preparedness, or grouped trips, offering consistent warmth and shelter across scenarios—all without sacrificing portability.
