What Features to Look for in an Emergency Safety Blanket 

When choosing an emergency safety blanket, sometimes referred to as a space blanket or thermal blanket, it’s important to consider several factors.

Here are some key features to look for:

Material and Construction

Look for blankets made from durable and heat-reflective materials, such as mylar or aluminized polyester. These materials are lightweight, compact, and provide excellent thermal insulation for emergency situations or outdoor activities.

Wool blankets can also work as effective emergency blankets. 

Mylar is a brand name for a type of thin polyester film that was developed by DuPont in the 1950s. It is strong and heat resistant, and it has been used by NASA for protection in extreme temperatures during space exploration. 

Mylar emergency blankets can also be used as a signaling device due to their reflective surface.

Size and Portability

Ensure the blanket is large enough to cover your entire body. Most emergency blankets come in a standard size of around 52 x 82 inches, but always check the dimensions to make sure it is large enough.

Also check the size of the blanket when folded or rolled into a stuff sack or bag, to make sure it can fit easily into a backpack or emergency kit or into the back of the car. 

For camping and outdoors activities, a packable emergency blanket is particularly useful. On this list, we chose the Gear Life Bivvy and TACT Bivvy 2.0 for their small packable sizes. Some emergency blankets come individually wrapped, making them easier to carry and protect from wear and tear.


A good emergency blanket should have a highly reflective surface to efficiently reflect and retain body heat. The reflective coating helps in preventing heat loss by reflecting a high percentage of the body’s heat back to the person using the blanket. 

The reflective surface is also eye-catching and visible in an emergency. 

Waterproof and Windproof

Your emergency blanket should offer protection from wind, rain, and snow. This is a key feature since inclement weather can further contribute to heat loss.

A waterproof emergency blanket will help keep you dry in wet conditions, help you stay insulated, and can combat signs of hypothermia. 


Some emergency blankets are more robust and tear-resistant than others, which is important for outdoor adventures or situations where the blanket may be subjected to rough handling.

Some emergency blankets come with reinforced grommets or corner ties, allowing you to use them as a makeshift shelter or tarp. This adds an extra layer of versatility to the blanket.

Brand and Reviews

Research the brand before you click “buy now”. It is a good idea to purchase an emergency blanket from a company with expertise in survival products and/or one that has a good reputation in the outdoor space.

Always read customer reviews to find out key information about the emergency blanket’s performance in the real world, as well as details such as size and the quality of the material.

Temperature Rating

While emergency blankets are generally designed to provide thermal insulation, some may have specific temperature ratings. Consider blankets that are suitable for the expected climate conditions in your region.


Emergency blankets are generally reasonably priced. If you are looking for a wool blanket, it will be a more expensive option. You can find them for prices as low as $5, but you might want to spend more if you are looking for one that you would like to last a long time.  

Frequently Asked Questions 

Do wool blankets make good emergency blankets? 

Wool blankets can make very good emergency blankets since they are warm and can be used over and over again. They can offer great comfort in emergency situations, especially in cold weather.

However, an emergency wool blanket does not offer the same insulating properties as a mylar blanket, and it is not as packable, portable, or lightweight. 

Are emergency blankets reusable?

The reusability depends on the specific type and design of the blanket. Some mylar emergency blankets made of a thin, metallic polyester film are intended for single-use or limited use.

These types of blankets can be thin and fragile, and with repeated use or folding, they may develop tears or lose their effectiveness. 

If you’re looking for a more reusable option, you might consider camping blankets made from other materials, such as durable fabrics or wool. While these may be heavier and bulkier than mylar blankets, they can offer greater longevity and may be suitable for more extended or repeated use.

How long do emergency blankets last?

It will depend on their use and the fabric that they are made from. Always check the manufacturer’s guidelines to check if the blanket is reusable or single use. 

If the blanket shows signs of damage, wear, or loss of effectiveness, it’s advisable to replace it to make sure it works well in emergency situations.

Can emergency blankets be used for medical purposes?

One of the primary uses of emergency blankets is to prevent and manage hypothermia. They are designed to reflect and retain body heat, helping to keep an individual warm in cold conditions.

They can also be used to manage shock. In cases of trauma or severe injury, individuals may go into shock, and one symptom is a drop in body temperature. Wrapping the person in an emergency blanket can assist in maintaining his or her body heat and addressing this aspect of shock.


An emergency or safety blanket is an essential addition to your emergency kit. If you don’t already have one, now is a great time to make the purchase. Also check out all the essentials to pack for a camping trip.

Emergency blankets are useful for many outdoor pursuits, such as camping or backpacking, but they also have a purpose in everyday life. Purchase a multi-pack to store in the back of the car in case of emergencies.
