Survival blankets are a must-have if you want to stay well-prepared for an emergency.
I admit it is a smart move to have a blanket or two to back you up when in need, but it doesn’t even have to be an emergency to really need one. I am sure you will agree with me when I say that it is better to have one and not need it than need one and not have it.

A survival blanket is an irreplaceable item if you find yourself stuck in the wilderness.
Up in the mountains, even during the summer, the temperatures can get very low. So anything that can keep you warm is well worth having.
Hypothermia can occur more quickly than most people realize. It could just take ten or fifteen minutes. And if you don’t have anything to shield you from the wind and rain, things may get even worse. Every year, hypothermia takes more than 20,000 lives in the United States alone.
But not all survival blankets are made equal; before you put them to the test, some might seem like a smart idea.
For this reason, you will discover a detailed list of all the information you want on the best survival blankets available here.
There are many various names for survival blankets, including space blankets, emergency blankets, Mylar blankets, thermal blankets, and a lot more.
One can easily get a little lost and confused when trying to find the right survival blanket for their needs. This is why below you will find detailed information on several different topics like:
- Everything you need to know about the different types of survival blankets.
- The best survival blankets.
- How to use a survival blanket.
What Are the Different Types of Survival Blankets?
Survival blankets can be made from a variety of different materials—each with its pros and cons.
Animal Hide and Skin
Today things are a lot different compared to before. Technology has constantly been improving over the past years, and we can certainly take advantage of that.
However, a long time ago, animal hide was the best material for creating survival blankets and protection against harsh elements. The animal hide is thick and durable but very heavy and not exactly what one would consider compact.
Mylar is a polyethylene terephthalate (PET), which has been stretched into a polyester film. And it is one of the most commonly used materials used for making survival blankets.
These are also known as space blankets because Mylar was used by NASA for its reflective and insulating capabilities.
Mylar is usually one of the cheapest and lightest forms of insulation.
It can provide good protection against the elements, including water, wind, snow, and more. It is usually able to retain and reflect back high amounts of the body’s temperature.
When it comes to UV light, Mylar usually does have some very low transparency depending on its thickness, so it will not reflect all UV light.
One of the downsides of Mylar blankets is that they are very noisy.
Mylar is also super thin, which could be both an advantage or a disadvantage depending on how and where it needs to be used as it can easily tear or puncture.
Wool has been used throughout the years for cloaks. It is one of the best types of textile fiber that will keep you warm and protected, even when it gets wet.
Wool does not produce any significant noise but takes a lot more space compared to Mylar blankets.
However, compared to Mylar, it is a great deal more durable and long-lasting. A wool fiber with appropriate care can last 20 or 30 years. Mylar can readily ripped and damaged, especially when used in harsher environments, whereas wool can tolerate much more use.
Polar fleece is another excellent alternative since it is very compact and has excellent protective capabilities.
However, polar fleece is usually not windproof but, on the other hand, does not absorb moisture. Polar fleece can still provide good insulation, even when it gets wet.
Down—including synthetic down—is a superb material for anything survival. It can be used for survival blankets, sleeping bags, and so much more.
Down is capable of generating lots of warmth and keeping your body from losing its body heat. Synthetic down, on the other hand, can do that even if it gets wet.
Compared to fleece, down is a lot warmer.

Best Way to Use a Survival Blanket
Survival Blankets Do Not Generate Heat
Although they will keep you warm, survival blankets don’t produce any heat on their own. They serve as a barrier, shielding your body from the wind and the cold and keeping it warm.
Some can retain about 70%, while others up to 90% of your body heat. The higher the percentage—the lower the heat loss. Depending on the area where you live, you may want to have as much protection as possible, especially during the colder months of the year.
In the same manner, Mylar blankets can be used to reflect heat if you have no other way of protecting yourself from the sun.
Depending on the type of survival blanket you have, it may be advisable to have a few more extra blankets in case the others tear or break.
This is important, especially when it comes to Mylar blankets, as they can tear and puncture quite easily in rough conditions.
Make Sure You Are Well Protected
The bigger the survival blanket, the more of your body will be covered. There will be no point in covering your head and upper body if the blanket is so small your lower body is left outside exposed to the cold weather.
It defeats the whole purpose, so make sure you pay special attention to the dimensions of the survival blanket before buying it.
Use Your Blanket With Care
Most of the fabric-based survival blankets are very tough and will not tear easily. However, that is not the case with Mylar blankets.
Even the thickest Mylar can be easily punctured on hard and sharp surfaces.
Make sure you are exercising extra care when taking your blanket out and while using it. Even if it tears, do not panic; this is why it is a good practice to have a few extras.
Do Not Cover Your Nose
There are no hard and fast numbers here, but experts believe that we can be losing between 10 to 45% of our body heat through our heads. This is why wearing a hat is so beneficial during the colder months.
However, even if you decide to cover your head with the survival blanket, make sure that your nose is not fully covered. If you cover your face and nose fully, you will be breathing in more CO2, and you will be trapping all the humidity from your breath inside.
This will create condensation inside the blanket and will negatively affect your body temperature.
Survival Blankets Are Versatile
Survival blankets, especially Mylar ones, are incredibly versatile and can be used in many different ways. They can be used for:
- Collecting water;
- Signaling planes and people at long distances;
- Building shelter;
- Ground cover;
- Protection for accessories, phones, keys, personal documents, and so much more.
Knowing how to adapt and use your blanket in different situations may literally save your life.
A survival blanket is one of the must-haves when it comes to preparing your emergency and first aid kit.
One of our first instincts is to make sure we are stocked with plenty of food and water, but all the water and food will do us no good if we are left stranded in the wilderness without any protection against the cold.
The good news is that a survival blanket is both an inexpensive and lightweight way to give us a better chance of surviving in the wilderness.
