Every survival kit needs an emergency blanket — a versatile piece of survival gear that can prevent hypothermia and even double as a shelter. It’s one of the necessary supplies that you bring along, hoping to never have to use. Made out of reflective, thin, and durable material, these blankets are designed to keep heat in. The waterproof and sturdy nature of these blankets lets you convert them into a shelter if needed. Your next hike or camping trip is likely not going to involve Arctic warfare, but with how cold it gets at night, it might start to feel like it. If you get waylaid on your travels, a fun trek can turn into a survival situation with alarming speed. Instead of getting caught unprepared, simply tuck one of the best emergency blankets in with your gear and be ready for everything.
To help you track down a high-quality model, we’ve broken down the top options, along with some tips on making the right pick.
If you’re looking for something heavy-duty enough to handle extreme outdoor conditions, check out the Swiss Safe Store Emergency Mylar Blankets. These blankets are made out of double-sided mylar material, reinforced with aluminum to promote thermal benefits. A military-grade material, the 12-micron metal components keep the blankets lightweight without compromising insulation. Weighing only two ounces, these thermal blankets can retain as much as 90 percent of your body heat. At 52 by 82 inches (when expanded), you can use these blankets either as a base, a shelter, or a jacket. Entirely waterproof and compact enough to put in any bug-out bag, these blankets are definitely worth having around.
Want to create a survival kit that can keep up with your outdoor habits but won’t break the bank? Consider the Anmeilu Emergency Mylar Thermal Blanket, a solution that comes in a set of four and offers a lot of protective surface area. At 55 by 84 inches, the blanket can easily accommodate two adults. The thermal benefits come from the aluminum-reinforced mylar material. This reflects sunlight outwards, keeping you cool in case exposure or heat stroke is a concern. On the other hand, you can use this material to hold in up to 90 percent of your body heat in cold conditions. Thick enough to last overnight, these blankets fold into a compact structure so you can fit them in with your other gear. Affordably priced, this set of four blankets is a worthy supply to keep on hand.
Do you often find yourself contending with outdoor conditions and want to be prepared? Take a look at the Primacare HB-10 Emergency Mylar Blankets, a survival supply that comes with 10 individual blankets. Each is sealed separately, coming in a compact package so that you can fit it in with any of your other gear. The blanket is so lightweight that you won’t notice it there (until you need it, that is). When you expand the blanket, it gives you a full 52 by 84 inches of space. The metallic design is there to reflect light outwards to protect from heat or keep your warmth inside the blanket in order to prevent hypothermia. Since the blanket is so sizable and waterproof, you can also use it as a make-shift shelter or sleeping bag. Durable and easy to take wherever you go, these emergency blankets are an essential component of any survival kit.
Want something that has a bit more substance? Survival gear is only viable if it is compatible with your surroundings, after all. So, if you are tackling rugged outdoor conditions and want to prepare, the Go Time Gear Life Emergency Sleeping Bag is a good way to go. Though it is a bit bulkier than the standard mylar survival blanket, it weighs just over four ounces. Expanding to give you 21 square feet of space, it is made out of a durable, waterproof nylon material. Coming with a survival whistle, paracord, and carrying case, this blanket is highly versatile. You can use it as a sleeping bag, tarp, shelter, or warming blanket. Powerful survival gear, this emergency blanket is a must-have for hikers and prepping enthusiasts.
Do you plan to contend with the harshest weather conditions, or at least want to be prepared in case life takes you there? If so, be sure to equip your gear with the Bearhard Heavy-Duty Emergency Blanket. It is built to take up very little space when stored, though can expand to give you 35 square feet of space. The material consists of aluminum-laminated material that reinforces the textile fabric. Thanks to the lamination process, the blanket is able to hold up to 93 percent of your body heat. It is thick enough to resist wind, waterproof enough to weather a storm, and durable enough to withstand abrasion. A multi-use survival tool that is meant to outlast any situation, this emergency blanket is definitely worth checking out.
Why should you trust us
I’ve been reviewing products for five years, focusing largely on tactical gear, automotive supplies, and other survival necessities. Using my educational background in the sciences and three years of experience as a news reporter, I curate fact-based reviews on which my readers have come to rely. My work is featured on The Drive, Car Bibles, and Narcity Media, and some of the most recent pieces I’ve done for Task and Purpose include reviews of thermoses, folding knives, and camo pants. All my work is done with a view to providing actionable advice for sourcing reliable products for everyday situations and survival scenarios.
The most common types of emergency blankets
This is easily the most common type of emergency blanket, originally called a space blanket. It is made out of mylar, an aluminum-based material that is lightweight yet not bulky. The blanket is designed to fold down compactly, fit well into any space, and be thoroughly waterproof. The key behind the material is to prevent natural heat loss by reflecting the energy back inwards and trapping it.
First crafted by NASA, these blankets have become one of the standards for first-aid kits. They feature a plastic coating that keeps the blanket dry and comes in a wide range of sizes (though the bigger they are, the easier they tear). A quality option will be able to reflect back anywhere from 90 to 97 percent of heat, making this type a very energy-efficient option.
Taking mylar technology to the next level, some modern emergency blankets use the metallic features of the blanket in conjunction with insulation. Keep in mind that, because of the extra material, these blankets are bulkier and moderately heavier than their mylar counterparts. In most cases, the blanket is made out of ripstop nylon.
These blankets are specifically designed for camping or hiking, meant to lend an extra level of security against the elements. In most cases, this type of emergency bag is reusable and generally more comfortable than thinner blankets. Typically, these blankets will come as a standalone.
What to look for when buying an emergency blanket
When you’re picking out your emergency blanket, there are a few important things to keep in mind. The first is considering where you are likely to use it. If you are more likely to find yourself battling a winter blizzard from your car, you’ll want something to fit in your trunk or glove compartment. Conversely, if you plan to go on a desert hike with nothing but a backpack, your emergency blanket needs to be lightweight, highly reflective, and compact.
Once you’ve settled on where you plan to store the blanket, consider the versatility and durability of the blankets you’re investigating. If you are getting only one, check that you can fold it back down after use or that the set comes with more than one blanket. Ensure that it is tough enough to withstand real-life conditions (like the models on this list). The last thing you want in a survival situation is your gear giving up on you, so make sure the blanket can keep up.
Finally, ensure that your blanket is completely waterproof. Be sure that the fabric isn’t likely to rip, because no matter how water-resistant it is, a tear will lessen the benefit. Check that the moisture is repelled along with the heat and the cold. So long as your blanket can protect you from the elements and is big enough to cover you thoroughly, it should be a great way to go.
The advantages of owning an emergency blanket
Having an emergency blanket is more than beneficial. It is utterly essential to any survival kit, bug-out bag, or prepper bunker. Emergency blankets are designed specifically for extreme conditions, often going by the phrase ‘space blankets.’ They are made out of waterproof, reflective materials that can be used to keep heat in or repel it. As a result of this aluminum-integrated textile, you can rely on a quality emergency blanket whether the sun is scorching or you’re stuck in a blizzard.
Another key advantage of an emergency blanket is that, like any other survival gear that is worth its salt, you can use it in more than one way. This isn’t just about hot versus cold. It’s the fact that your blanket can double as a jacket and be used as a shelter. Provided you plan ahead and have reasonably easy access to the blanket in an emergency, it can surely help you get through a bind.
