Our gas heat quit in the January outage and blankets just weren't doing it. I got these after. It's crinkly and it won't win any awards for comfort, but I got in one on the couch as a test and I was warm in a few minutes. It packs down to nothing.

Tried it in the garage at 35 degrees. Warmer than my blanket.

She's got electric heat only. I worry. Now she has two.

How It Works
On a cold night, you lose heat to the wind and to the air around you.
- You get inside it. That keeps a pocket of warm air around your whole body. A flat foil sheet just lies on top of you and slides off.
- It reflects your own heat back.
- It blocks wind.
No power, no fuel and no setup. Unfold it and climb in. It opens to about 83 x 35 inches.
What It Does, and What It Doesn't
It blocks wind and holds your own body heat, so you stop losing what you've got. It doesn't create heat, so if you're already cold, it takes time.
- It's an emergency layer, not a camping bag, and it has no temperature rating.
- The ground still pulls heat. Put a pad, a car seat, cardboard or blankets under you.
- It's water-resistant, not waterproof.
- It can get damp inside from your breath. Keep your face out of the opening.
- It's thin. It can tear if punctured. Handle it gently.

Your furnace needs power too
A gas furnace still uses electricity to run. So when an ice storm takes the power out in January, the house starts cooling. In the 2021 Texas freeze, the state's final count was 246 deaths (NPR). You can't heat a whole house without power, and you don't need to. You need to hold the heat your body makes. That's what this does. It's small, so you can keep one for everybody in the house.
Small enough to forget. There when it gets cold.
A bag and not a flat foil blanket


The first night with no heat

The power goes
Picture an ice storm and lines down. The furnace stops. The house is fine for now.
The house cools
Everyone's in one room with sweaters on. Doors shut. It's holding, but it's going down.
Everyone gets their own
Blankets on the floor or sofa, then the bag. Faces out. You're holding on to your own heat.
Everyone got some sleep
The room is cold, but your own heat stayed in the bag with you all night. Fold it loosely and keep it handy for tonight.
Back in the sack
Repack it gently and store it cool and dry. It can be used again with care.
One per person, plus one in each car.

Questions people ask
Does it really work?
It closes around you, blocks wind and holds your own heat. Buyers give it 4.8 stars across 527 reviews. The best test is yours. Get in one on the couch inside your 30 days.
Is it hard to use?
No. There's no power, no fuel and no setup. Unfold it and climb in, with your face out. Getting it back in the sack takes some patience, so fold it loosely and keep it handy.
Will it keep me warm at a certain temperature?
We don't give a temperature rating, because we don't have a test to back one up. It traps body heat and blocks wind. It doesn't create heat. Treat it as an emergency layer.
Is it better than a foil blanket?
It closes around you, so it doesn't slide off and the wind can't get under it. If you own foil blankets, keep them. You'd want this for a long night.
Does it protect me from the cold ground?
Not much. The ground still pulls heat out through the bottom. Put a pad, a car seat, cardboard or blankets under you.
Is it waterproof?
It's water-resistant, not waterproof. It sheds rain and splashes. It isn't for standing water.
Will I get damp inside it?
You can, because your breath and body put out moisture and the bag holds it in. Keep your face out and open the top a little if it gets clammy.
Can I use it more than once?
Yes, with care. It's thin and can tear once it's punctured. Repack gently and store it cool and dry. It's for emergencies, not every weekend.
Will a bigger person fit?
It opens to about 83 x 35 inches, which is roomy for most adults. It's a narrow bag, not a bed.
We have a wood stove or generator. Do I need this?
If you're set, you may need fewer. Bags are for the room the stove doesn't reach, the night the fuel runs out, and the car.
Is it worth buying more than one?
Yes. It only holds the heat of the person inside, so plan one per person, plus one per car. Four singles cost $119.96. The Family Pack is $59.99, $15 a bag and $59.97 less. Sending some to the kids? Eight are $95.99, $12 a bag. The Household Planner can do the math.
Isn't this a bit much for someone who isn't a prepper?
It's four ounces in a drawer. You don't need a bunker. You need a way through one cold night.
How fast does it ship?
Standard shipping is $4.95 and Express is $9.95. Delivery times are on our Shipping and Returns page. Every order ships the next business day, tracked and insured. Have it before the ice storm is on the forecast.
What if I don't like it?
Try it for 30 days. If you're not happy, email us and we'll refund you. Unused or used. Just email hello@minimls.com.

Crinkles every time you move. Keeps you warm though.
Packed, it's like a large orange.
I'm 6'2 and could pull it over my shoulders.
The price per bag is much better.
You'll get a bit damp inside if you stay in all night. It's emergency gear, not a sleeping bag for camping.
Keep one in each vehicle for winter.
Getting it back in the pouch is a chore. Use it once and it won't fit as neat.
Tried it in the garage at 35 degrees. Warmer than my blanket.
Weighs nothing.
She's got electric heat only. I worry. Now she has two.
Scraped along the truck bed and didn't tear. I wouldn't drag it on rocks.
Came within what they said.
For what it costs, why wouldn't you.
Bright orange, easy to spot.
My brother keeps his in his pack.
Small, warm, done.
Have it before the heat goes out.
It packs to the size of your fist. Put one where you would look for it in the dark.
