IF IT HAPPENED TONIGHT...

  • A winter storm knocks out the power — and the heat.
  • A breakdown leaves your family stranded on a freezing roadside.
  • A wrong turn on a hike leaves you waiting hours for rescuers to find you.
  • An accident leaves someone injured and exposed to the cold while help is on the way.

Emergencies don't schedule themselves. Preparedness means having emergency protection ready before you need it.

“If Something Happened Tonight, Would You Have Enough?”

A single emergency can involve more than one person. Keep Mart Cobra Emergency Blankets ready for the people and places that matter.

MORE THAN JUST EMERGENCY WARMTH

ONE SMALL BLANKET. MULTIPLE WAYS TO PROTECT.

Most people know emergency blankets can help keep you warm.

But reflective Mylar can do much more than that.

Its reflective surface helps manage radiant heat, while the waterproof and windproof material can also serve as an emergency barrier, shelter, ground cover, or highly visible signaling surface.

That's why something that folds smaller than a deck of cards can be such a versatile piece of emergency gear.

HOW REFLECTIVE MYLAR WORKS

DESIGNED TO MANAGE RADIANT HEAT — NOT JUST TRAP WARMTH.

Your body is constantly giving off heat. In cold conditions, the reflective surface of a Mart Cobra Emergency Blanket helps reflect radiant body heat back toward you — reducing one way your body loses warmth.

But that same reflective principle can work in the opposite direction, too.

When positioned between you and strong sunlight, the reflective surface can help reflect solar radiant heat away — making it useful for emergency shade and reducing radiant heat exposure.

A LOT OF EMERGENCY UTILITY. ALMOST NO SPACE REQUIRED.

At home. In vehicles. In emergency kits. In go bags. And anywhere else you might need one.



WHO ELSE WOULD YOU WANT PREPARED?

PREPAREDNESS DOESN'T STOP WITH YOU

You may already know where you'd keep Mart Cobra Emergency Blankets — at home, in your vehicles, in emergency kits, or in a go bag.

But what about the people you care about?

Parents. Grandparents. Children away from home. Friends or family who may not have thought about emergency preparedness yet.

Emergency protection only helps when it's already where it's needed.

KEEP SOME. SHARE SOME. HELP MORE PEOPLE BE PREPARED.

Mart Cobra Emergency Blankets are compact enough to store almost anywhere — and easy to share with the people you want prepared.

WHY CUSTOMERS KEEP MART COBRA EMERGENCY BLANKETS READY

From vehicles and go bags to family emergency kits, customers are finding plenty of places to keep emergency warmth ready.

GREAT TO HAVE IN A DAY PACK FOR EMERGENCIES!
I got these as a part of a kit I was putting together for my son to keep in his Camelback backpack. We do recreational mountain biking and day hikes and on a recent trip biking he hit a rock and damaged his bike to the point he wasn't able to ride it. I walked with my son to a road about a mile and half away while my wife and daughter continued to ride back to the car. We were fine but it made me think that he should have a blanket for emergency supplies my wife and I also have in our Camelback backpacks since he may be venturing off on his own..

KEEP YOUR LOVED ONES SAFE. PERFECT FOR STORAGE IN AUTO.
I bought several to keep in vehicles for emergency use in cold or overnite stays in a stranded car. They do not take up space and give you peace of mind. Especially for kids, elderly or handicap individuals they really keep you warm and are very light weight.

SURPRISINGLY WARM
I bought these in case we lost power during winter storms. I decided to test the blankets just for kicks. Using two, I was surprised that something so light and thin could actually keep you warm in an understatement. I'm happy to have these in my storm basket and a set in my car in case I ever need them.

COMPACT ADDITION FOR MY CAR AND HURRICANE EMERGENCY KIT
COMPACT. It is going to be added to my hurricane kit and for my car's emergency supplies... It may not be able to keep the pocket knife in my pocket, but definitely earns a spot in my emergency kit.

WONDERFUL WAY TO COOL HOME
Extremely warm the prior summer as interior window insulation during hot summer months. They reflect the sun's radiant rays away from the house, reducing the interior temps by 5° to 10°. Also, it darkens the room, but one can still see through them.

EMERGENCY BLANKET OR SLEEPING BAG — WHICH IS RIGHT FOR YOU?

Same reflective Mylar principle. Two different ways to prepare.

VERSATILITY OR ENCLOSED WARMTH?

Mart Cobra Emergency Blankets are designed for versatility. Wrap one around your body, create emergency shade, use it as a weather barrier, ground cover, signaling surface, or makeshift shelter.

But when enclosed cold-weather protection is the primary goal, a Mart Cobra Emergency Sleeping Bag offers a bivy-style design that surrounds your body.

Many emergency kits can benefit from having both.



BUILD THE EMERGENCY SETUP THAT FITS YOUR NEEDS.

Emergency Blankets: Versatile protection for more people, places, and situations.

Emergency Sleeping Bags: Add enclosed protection anywhere cold-weather exposure is a bigger concern.

Frequently Asked Questions

Mart Cobra Emergency Blankets use reflective Mylar to help reduce radiant heat transfer. In cold conditions, the reflective surface can help reduce radiant body heat loss. The material also creates a lightweight windproof and waterproof barrier.

There isn't one number that's right for everyone. Think about people and places, not just one emergency kit.

Consider keeping emergency blankets at home, in each vehicle, in go bags, with outdoor gear, and anywhere else you may need emergency protection. You may also want some available for family members or others you care about.

The Mylar material is waterproof and windproof, allowing the blanket to serve as a lightweight barrier against wind and moisture.

It can also be used as an emergency weather shield, ground cover, or makeshift shelter when needed.

Both use reflective Mylar technology, but they're designed differently.

A Mart Cobra Emergency Blanket is an open, highly versatile sheet that can be wrapped around the body or used as a weather barrier, ground cover, signaling surface, emergency shade, or makeshift shelter.

A Mart Cobra Emergency Sleeping Bag creates an enclosed bivy-style space around the body, making it particularly useful when the primary goal is emergency warmth and protection from exposure.

Good places include your home emergency supplies, each vehicle, go bags, backpacks, camping gear, RVs, workplaces, and anywhere else you may need emergency protection unexpectedly.

Because each Mart Cobra Emergency Blanket folds smaller than a deck of cards, keeping them in several locations takes very little space.

Like most Mylar emergency gear, the material can make some crinkling noise when moved. The tradeoff is an extremely lightweight and compact design that's easy to keep ready for emergencies.

Orders are generally processed within 1–2 business days. Once shipped, you'll receive tracking information by email. Delivery times vary depending on your location and shipping method.

Yes. Reflective Mylar isn't only useful in the cold. When positioned appropriately between you and strong sunlight, the reflective surface can help reflect solar radiant heat away, making it useful for emergency shade and other radiant-heat protection.

Each Mart Cobra Emergency Blanket unfolds to approximately 82" × 52", providing full-body coverage for an adult.

Yet folded, each blanket is smaller than a deck of cards, making them easy to store in vehicles, emergency kits, go bags, backpacks, RVs, and more.

Yes, if the blanket remains in good condition after use, it can be carefully folded and reused.

Because emergency Mylar is extremely lightweight, however, it can be punctured or torn with rough handling. Inspect it before relying on it again.

Beyond wrapping around the body for emergency warmth, the reflective Mylar can serve as a weather barrier, ground cover, signaling surface, emergency shade, or makeshift shelter.

Its compact size makes it useful for situations where carrying traditional shelter or protective gear isn't practical.

Emergency Mylar blankets don't have a typical expiration date like food, batteries, or medicine. When stored unopened in a cool, dry place and protected from damage, they can remain ready for emergency use for a long time.

Inspect the packaging periodically and replace any blankets that have been damaged.

Yes. The Mylar material can provide a temporary barrier against ground moisture when needed.
