TerraShell is designed to boost your survival temperature significantly. While it is not rated for a specific "degree" like a sleeping bag (because it relies on YOUR body heat), users report staying warm in freezing cars and unheated homes down to 30°F and below when wearing normal clothes inside the bag.

TerraShell is engineered for emergency survival. Unlike flimsy mylar blankets that rip on first use, our 26-micron polyethylene material is built to withstand the conditions that matter most, when your life depends on it. Can you fold it back up afterward? Yes, carefully. But like any emergency gear that gets deployed under stress, the integrity degrades after use. Most families keep fresh units in their go-bags and cars, and use their first one for practice or camping so they know exactly how it works when seconds count. 

We specifically designed it in Army Green based on feedback from tactical experts. In a civil crisis (like a blackout or riot), you do not want to be a bright orange beacon advertising that you have supplies. Green allows you to stay hidden. If you need rescue, use the integrated whistle.

Absolutely. The "Vehicle Team Kit" and "Family Bundle" are our most popular gift options, especially for new drivers or elderly parents living alone.

Wool is heavy, bulky, and expensive. If it gets wet, it loses insulation. TerraShell fits in your pocket, costs a fraction of the price, blocks wind 100%, and stays waterproof.

To keep the price affordable (under $20/bag in bundles) while using high-grade 26-micron material, we cut out the retailers and sell directly to you.

We offer a 120-day "Warmth Guarantee." If you aren't satisfied, simply email us for a full refund. You can even keep the bonus guide.
