Don't Let Your Family Be the Next Headline
Every year, thousands of American families face life-threatening colds without power.
 Grid failure
Texas 2021: 4.5 million without heat for days, homes dropped to 30 ° F
 Vehicle Strandings
Buffalo 2022: Dozens froze to death trapped in cars during blizzards
 Fuel Shortages
Northeast Crises: Propane and oil deliveries fail when roads close
 Aging infrastructure
70% of US power grid is over 25 years old and failing in storms
Winter storms, grid failures, and highway closures keep catching families off guard.

Most people still rely on hope and blankets as their only "plan B".                          
When Heat Disappears, You Have Just 3 Hours
In a freezing emergency, hypothermia becomes life-threatening within hours, not days. 

Children lose body heat 4x faster due to smaller body mass. 

🚨 Hour 1-2: Shivering, numbness, loss of dexterity

⚠️ Hour 3-6: Confusion, drowsiness, organ failure risk

Meanwhile, emergency crews cannot reach you during blizzards. Roadside assistance takes days. Gas stations run dry. Neighbors turn desperate.

Relying on blankets in a crisis can pull heat away from your body faster.
"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...
 Trusted by Over 50,000 American Families
Introducing TerraShell, Protection You Can Count On

This survival bivy exists for one reason—Search & Rescue teams kept seeing the same tragedy.


Every backup plan families had needed power, fuel, or fire. When all three were gone, they had nothing.


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.

*Not affiliated with, endorsed by, or sponsored by NASA.

🏆 Award Winning Design
So Easy And Quick, Anyone 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. Designed to retain critical body heat in freezing conditions.


Climb into the TerraShell bivy. 


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.

Built on the Hypothermia Wrap Protocol

When the heat dies and the cold starts winning, there's only one rule: STOP HEAT LOSS. 


That means three things happening at once: block the wind, block the moisture, contain the heat. Most emergency blankets do one. Maybe two.


 TerraShell was designed around the full protocol. One action. One layer. Complete thermal containment. 


The same logic taught in wilderness medicine, military SERE training, and cold-water rescue certification—compressed into something even kids could deploy in seconds.

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 safety specialist with 18 years of experience, I've seen too many situations go wrong because people were 'just waiting for help.' You're on your own for the first 72 hours minimum. I keep TerraShell bivys in my own home, truck, and go-bag. During the last freeze, I watched families struggle with wet blankets while those with thermal shells stayed warm. This isn't paranoid prep—it's basic physics. Like a seatbelt, you hope you never need it, but you're grateful 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?

TerraShell is emergency gear, not camping equipment. Like an airbag or a flare, it's designed to deploy once when your life depends on it. That's why smart families keep one in every car, every go-bag, and every bedroom closet. When the heat dies at 2am, you're not digging through the garage looking for 'the family bivy.' Everyone grabs their own and stays warm. At this price, full coverage for a family of four costs less than one tank of gas.

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 10-15 business days.
