Don't let your family be the next headline
Every winter, families across the U.S. lose heat because of storms they saw coming.
- Grid failure
Millions without heat
In February 2021 a winter storm cut power to more than 4.5 million homes and businesses in Texas, many of them for days.
- On the road
Stuck on the highway
In January 2022 a snowstorm stranded hundreds of drivers on I-95 in Virginia, some of them overnight, in freezing temperatures.
- Fuel
Deliveries stop
When roads close, propane and heating oil can't get through, and gas stations can run dry. A full tank of hope doesn't heat a house.
- Aging grid
Older than you think
The Department of Energy reports that about 70% of U.S. transmission lines are over 25 years old. Severe storms hit them hard.
Winter storms, grid failures and highway closures keep catching families off guard. Most people still rely on hope and a pile of blankets as their only plan B.

Cold works faster than you think
Hypothermia is when body temperature drops below 95°F. It can happen indoors, and children and older adults lose heat fastest. These are the warning signs the CDC lists, in the order families usually notice them.
- First
Shivering and numb hands
The body tries to make heat. Fingers stop working well; simple tasks get hard.
- Then
Exhaustion and confusion
Thinking slows down. People fumble, forget, and stop noticing how cold they are.
- Danger
Slurred speech and drowsiness
This is a medical emergency. In babies, look for bright red, cold skin and very low energy.
Meanwhile, emergency crews and roadside help may not be able to reach you until the roads are cleared. If someone shows these signs, call 911.

Why most backup plans fall short
- Blankets
They leave gaps
They slip off, let cold air in at the sides, and cotton loses most of its warmth once it's damp from breath or snow.
- Running the car
Fuel and fumes
Gas runs out, and if snow blocks the tailpipe, carbon monoxide can build up inside the car.
- Space heaters
Useless in a blackout
They need power. A generator needs fuel and must never run indoors or in a garage.
- Fireplace
If you have one
Most modern homes don't, and it needs dry wood stored before the storm.
- Waiting for help
Help can be slow
During the 2022 Buffalo blizzard, emergency vehicles couldn't get through for hours. Hope isn't a plan.
What you actually need: a way to keep your own body heat around you, anywhere, without power, fuel or help.
No gas. No batteries. Just climb inside and get warm. That's the Ember Shield.
Protection you can keep in a glovebox
We made the Ember Shield for one reason: most families' backup plans need power, fuel or a fire. When all three are gone, they have nothing.
The Shield is an adult-size thermal bivy with a reflective lining. It sends the heat your body gives off back to you and closes around you, so wind and wet stay outside.
- Adult size, with a drawstring hood
- Reflective inner lining
- Olive green outside
- Rescue whistle on the cord
Warm in under a minute
No batteries, no parts to break, nothing to set up.
- 1
Find a safe spot
The car, the living room, the basement: anywhere out of the wind if you can.
- 2
Climb in
Get in wearing your clothes and pull the hood drawstring around your face.
- 3
Rest and stay warm
The reflective lining sends your heat back to you. Need help? Use the whistle.
When the cold is winning: stop heat loss
Cold-weather first aid comes down to three things at once. Most emergency blankets do one, maybe two. The Shield is designed for all three.
- 1
Block the wind
A closed bag with a hood, so moving air can't strip heat away.
- 2
Keep the wet out
Plastic film doesn't soak up water like cotton does.
- 3
Keep the heat in
The reflective lining sends your body heat back instead of letting it escape.

Frequently asked questions
What temperatures does the Shield work in?
It isn't rated to a temperature like a sleeping bag, because the heat comes from your body. It keeps that heat around you and the wind out; wear your normal clothes inside it and add blankets on top when you can.
Can I reuse it?
It's emergency gear, not camping equipment. You can fold it back after use, but replace it if the film is torn. That's why families keep one per person and one per car instead of sharing.
Is it safe for children?
Yes, with an adult watching. Keep the face opening clear for breathing and never leave a young child alone in it.
Why is it green instead of orange?
Olive green is low-key at home and in the car. If you need to be found, use the whistle on the cord.
Can I give these as gifts?
Absolutely. They're a popular gift for new drivers and for parents who live alone.
How does it compare to a wool blanket?
Wool is warm but heavy and bulky, and it loses warmth when wet. The Shield fits in your hand, closes around you and keeps wind and wet out. Use both if you have them.
Why can't I buy it on Amazon or at Walmart?
We sell only here, direct to families, so we can keep the price down.
What's your return policy?
You have 60 days. If you're not happy, email us and we'll refund you.
