IF IT HAPPENED TONIGHT...

  • Your car breaks down miles from home.
  • A winter storm knocks out the power — and the heat.
  • Someone you care about gets stranded in freezing weather.
  • A routine trip turns into hours stuck in the cold.

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

“If The Temperature Dropped Tonight, Would You Be Ready?”

A Mart Cobra Emergency Sleeping Bag can only help if it's there when you need it.

BORN FROM SPACE-AGE TECHNOLOGY

THE SCIENCE BEHIND EMERGENCY WARMTH.

In the 1960s, NASA helped pioneer the lightweight reflective insulation technology that became known through the “space blanket.”

Today, that same basic principle is used in emergency gear around the world.

REFLECT BODY HEAT — DON'T JUST COVER UP.

The Mart Cobra Emergency Sleeping Bag uses a reflective Mylar interior to help redirect up to 90% of your body heat back toward you.

Its enclosed bivy-style design surrounds your body, helping reduce the open gaps of a flat emergency blanket.

BUILT FOR MORE THAN WARMTH.

The windproof and waterproof exterior helps provide a barrier against wind and moisture.

And at under 5 oz., it packs small enough to keep almost anywhere.

WHO ELSE WOULD YOU WANT PREPARED?

PREPAREDNESS CAN GO BEYOND YOUR OWN HOME.

Maybe you keep Mart Cobra Emergency Sleeping Bags at home, in your vehicles, in your go bags, or in the RV.

But then think about the people you care about.

Parents. Grandparents. Adult children. College students away from home.

It doesn't take long for several sleeping bags to have a place and purpose.

Emergency warmth only helps when it's already where you need it.

WHY CUSTOMERS KEEP MORE THAN ONE EMERGENCY SLEEPING BAG

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

A lot of room in the emergency sleeping bags
I keep several Mylar emergency blankets since they're compact and easy to store but when I saw these I opted to order a 3 pack and check them out. I opened one when they arrived and REALLY like emergency SLEEPING BAGS. So much room and very warm. I'm ordering additional bags so everyone in the family will have one in their bug out bag.

Great emergency sleeping bags! We put one in each of the cars, just in case. Hope we don't need them, but like to have them in the event we get caught out in the weather.

EMERGENCY SLEEPING BAG OR EMERGENCY BLANKET?

A well-prepared emergency kit can have both.

SAME REFLECTIVE IDEA. DIFFERENT PURPOSE.

Emergency blankets are incredibly versatile. They can be wrapped, draped, used as a cover, or positioned as a barrier in a variety of emergency situations.

But when keeping your body covered and warm is the priority, an enclosed sleeping bag has an advantage.

The Mart Cobra Emergency Sleeping Bag surrounds your body with reflective Mylar, helping reduce the open edges you'd have when wrapping yourself in a flat blanket.

BUILT SPECIFICALLY FOR EMERGENCY WARMTH.

Instead of constantly adjusting a flat sheet around your body, you simply climb inside.

The enclosed 7' × 3' bivy-style design gives you full-body coverage while remaining compact enough to keep with your emergency supplies.

Both are valuable emergency tools. The sleeping bag is the one built specifically to surround you when warmth matters most.

Frequently Asked Questions

A fire blanket is a tightly woven fiberglass sheet designed to smother a small, contained fire by cutting off its oxygen supply. Pull the tabs to remove the blanket from its pouch, then carefully lay it completely over the flames.

If a fire is already large, spreading rapidly, or cannot be safely approached, evacuate immediately and call emergency services.

Mart Cobra Fire Blankets are designed for small, contained household fires, including kitchen grease and oil fires, stovetop fires, electrical fires, and clothing fires.

Do not attempt to fight a fire that is large, spreading rapidly, or blocking your exit. Evacuate and contact emergency services.

No. The blanket contains no powder or chemical extinguishing agent. It smothers the fire by cutting off its oxygen supply, so it does not leave the residue or cleanup associated with a dry-chemical fire extinguisher.

The Mart Cobra Fire Blanket is made from tightly woven fiberglass and is heat-tested up to 1,076°F, or 580°C.

Mart Cobra also states that its fire blankets are CE and SGS certified under the EN 1869:2019 fire-blanket standard.

A fire blanket can only help if it is close enough to reach when a fire begins. Fires can start in kitchens, garages, laundry rooms, workshops, near fireplaces, and around outdoor grills.

Keeping blankets in multiple high-risk locations means you do not have to run across the house or toward a fire to retrieve one. The larger bundles are designed to make it easier to place protection throughout your home.

If your Cobra Fire Blanket is used during a fire, we recommend replacing it rather than returning it to service. Through our Lifetime Warranty, qualifying blankets used during a real household fire may be eligible for replacement. Complete warranty terms are included with every order.

Orders are generally processed within 1–3 business days. Once shipped, you'll receive tracking information by email. Delivery times vary depending on your location and shipping method.

Mart Cobra Fire Blankets are designed and tested in Austin, Texas, and manufactured by Mart Cobra's production partners around the world. Mart Cobra is a veteran-operated, family-owned company based in Texas.

Follow these three basic steps:

Pull: Grab the tabs and release the blanket from its pouch.
Cover: Carefully lay the blanket completely over the flames to cut off the fire's oxygen supply.
Leave It in Place: Keep the fire covered until you are certain the flames and heat have subsided.

Always assess the situation first. Fire blankets are intended for small, contained fires that can be approached safely.

A fire blanket smothers a small fire by cutting off its oxygen supply. It does not discharge powder or another extinguishing agent, so it does not leave the chemical residue associated with many traditional fire extinguishers.

Fire blankets and fire extinguishers serve different purposes. A fire blanket is designed primarily for small, contained fires, while the correct type of fire extinguisher may be needed for other fire situations. Many households choose to keep both available.

The standard Mart Cobra home fire blanket measures approximately 40 inches by 40 inches, or 1 meter by 1 meter. It is designed to cover many common small kitchen and stovetop fires while remaining compact inside its storage pouch.

Store your Cobra Fire Blanket anywhere a small fire is most likely to start—and where you can reach it within seconds. Common locations include the kitchen, garage, laundry room, workshop, RV, near an outdoor grill, or anywhere else you may need immediate access.

The best fire blanket is the one that's close enough to reach when it matters most.

The mounting hooks are designed to be installed without tools. They allow you to keep each blanket visible and within easy reach in the areas where it may be needed.

Mount the blanket somewhere accessible, but not so close to a likely fire source that you would have to reach through flames to retrieve it.

If you use your Mart Cobra Fire Blanket on a real household fire, Mart Cobra will replace it.

Complete lifetime replacement warranty details are included with every order.

Returns may be requested within 30 days after the order is marked delivered. Returned products must be unused, unworn, in their original packaging, and accompanied by proof of purchase.

Before returning an order, contact support@martcobra.com to request a Return Authorization Number.

Customers are normally responsible for return shipping unless the return is caused by an incorrect or defective item. Mart Cobra does not charge a restocking fee.

Email us your questions at support@martcobra.comand we will be happy to answer any questions you have.
