Emergency Thermal Sleeping Bag

"But I Can Just Use Blankets... Right?"

Why Your Backup Plans Won't Work When Crisis Hits

Cotton Blankets

They absorb moisture from your breath and sweat. Once damp, they suck heat AWAY from your body 25x faster than air.

Running the Car

Gas runs out in hours. Idling risks carbon monoxide poisoning. Once the engine dies, the car becomes a steel freezer.

Electric Heaters

Useless in a blackout. Require massive generators most families don't have. Dangerous fire hazard indoors.

Wood Fireplace

Most modern homes don't have them. Inefficent. Requires dry wood you likely don't have stored. Smoke risks.

Wait for help

911 lines jam instantly. Snow plows get stuck too. In Buffalo, help took 48 hours. Hope isn't a plan.

👉 What You Actually Need:

Immediate access to trapped body heat in ANY environment.

No gas. No batteries. No heavy wool. No government help...

Just climb inside and get warm. That's TerraShell...

Introducing TerraShell, Protection You Can Count On

This innovative survival bivy could save your life for a simple reason—it was developed by an expert who's been there...

Andrew, a Search & Rescue specialist who watched families freeze in their own homes because their "emergency blankets" got wet and failed.

TerraShell uses NASA-inspired "Radiative Mirror" technology that turns your own body into a furnace in seconds.

Each bivy is designed to send 90%of your body warmth back toward you and create a windproof, highly water-resistant shell around your body.

🏆 Award Winning Design

So Easy And Quick, Even Your Kids Can Use It

No batteries, no parts to break, stupid simple design means you can count on it when your family needs it most.

Find any safe spot—car, living room, basement, or ditch. It doesn't matter how cold it is outside.

Climb into the TerraShell bivy and zip it up.

As you rest, the aluminized lining instantly reflects your infrared heat back to you—creating a warm micro-climate in minutes.

Most cheap "space blankets" rip easily and are bright orange targets. Not TerraShell.

Trusted by First Responders & Emergency Professionals

TerraShell is trusted by search and rescue teams, overlanders, and tactical experts who understand that "Cotton Kills".

While most cheap blankets absorb moisture and freeze, TerraShell creates a vapor barrier that keeps you dry and warm.

That's why first responders keep several TerraShells in their own homes, cars and go-bags and recommend it to their communities.

It's professional-grade protection designed for regular families. Those who prepare in advance are the ones who survive.

Real Families Who Finally Stopped Procrastinating

I'd been putting this off for two years. Every winter storm brought that sick guilt—'I should have emergency supplies'—but I never ordered anything. Too overwhelmed. TerraShell was finally simple enough. I ordered the 3-pack, and it arrived one week before the blizzard trapped us in the house with no power for 3 days. My kids sat in these in the living room playing games while it was 40 degrees inside. My husband, who thought I was crazy, said on night two: 'Thank God you didn't listen to me.' I can sleep now. Don't wait like I did.

As a rescue specialist with 18 years of service, I've zipped up too many body bags of people who were 'just waiting for help.' You're on your own for the first 72 hours minimum. I keep TerraShell bivys in my own home, in my truck, and in my patrol bag. I've recommended them to neighbors, family members, and anyone who asks what they should have for emergencies. During the last freeze, I watched families suffer under wet wool blankets. The ones who had thermal shells? They were fine. This isn't paranoid prepper stuff. It's basic physics. Like having a seatbelt—you hope you never need it, but you're grateful as hell when you do.

Frequently Asked Questions

What temperatures does TerraShell work in?

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.

Can I reuse the TerraShell bivy?

Yes! Unlike cheap "mylar blankets" that tear after one use, TerraShell is made from durable 26-micron Polyethylene. You can carefully fold it back up and place it in the stuff sack for multiple uses.

Is TerraShell safe for children?

Yes, but like all bedding, adult supervision is recommended for very young children to ensure they keep their face clear for breathing. The material is non-toxic and safe.

Why is it Green instead of Orange?

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.

Can I give these as gifts to family members?

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

How does TerraShell compare to a wool blanket?

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.

Why can't I just buy this on Amazon or at Walmart?

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.

What's your return policy? What if it doesn't work for me?

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.

How long does shipping take?

Orders ship from our USA and Asian warehouse within 24 hours and typically arrive in 7-10 business days.
