Best Survival Blankets
Survival blankets go by many names. Space blankets and emergency blankets are two of the most common alternatives.
They were developed in the 1960’s for the Apollo moon missions and have been used by NASA ever since. It quickly became apparent that their combination of high heat reflectivity and lightweight made them perfect for use in survival kits.
To help you find the blanket for you we’ve put together a list of the best emergency blankets across a range of features, prices, and types.
Survival Frog Tact Bivvy Emergency Blanket
The Survival Frog Tact Bivvy is an emergency survival blanket and sleeping bag. It’s designed to fold around the body and seal closed in much the same way a traditional sleeping bag would.
It’s made from an ultra-lightweight HeatEcho reflective polyester film to provide excellent heat retention for the smallest weight possible. The entire system weighs just 4.7 oz yet extends for 7 feet.
It’s not exactly a blanket, instead it’s folded and sealed into a tube that you can slip inside. This is great for keeping yourself warm but does limit how you can use it as a windbreak, heat reflector or rain cover.
Some really cool extras are built into the included carry pouch. A 130 decibel signaling whistle is attached to the end of the drawstring, which is itself a piece of useful paracord with interior cordage made of fire tinder.
The Tact Bivvy from Survival Frog is an innovative improvement on the traditional survival blanket. It completely envelopes your body to keep you warm in an emergency.
Swiss Safe Emergency Mylar Thermal Blankets
The Swiss Safe Emergency Mylar thermal blankets are lightweight and highly packable survival blankets. They’re based on the traditional mylar design and come in individually sealed pouches for easy packing and storage.
Each blanket is 6’10” long yet weighs just 2 oz. This gives you substantial coverage at a very low weight. One thing we really loved is how many options you have to choose from.
Swiss Safe offers their survival blanket in a range of bright colors and camo patterns. This is a great way to get your kids excited for preparedness.
The Swiss Safe Emergency Mylar survival blankets are lightweight and inexpensive emergency blankets. They provide effective warmth and are small enough to fit into any bag.
SOL Reflective Space Survival Blanket
The SOL (Survival Outdoors Longer) Reflective Space Survival Blanket is designed to be the next level in survival blankets. It’s made from vacuum-metalized polyethylene, a material that’s more durable than mylar yet has the same heat retention properties.
Each blanket measures 8 feet long yet weighs just 2.88 oz. One side is bright silver metallic and the other is emergency blaze orange. This helps make you as noticeable as possible to aid in recovery operations.
Because of its exceptional durability you can actually use the SOL survival blanket as a ground cover, rain tarp, and other general purpose use. This gives you a lot of flexibility in a survival situation.
Just about the coolest feature of this blanket is what’s on the outside. SOL printed detailed survival instructions right on the exterior of the blanket. These provide invaluable information to people when they need it the most.
The SOL Survival Blanket provides one of the best lightweight blanket options for an emergency pack. It’s durable, inexpensive, and provides you with excellent survival information.
Grizzly Gear Emergency Thermal Tent and Blanket
The Grizzly Gear line of Emergency Thermal Gear takes the basic space blanket to the next level. It includes a standard mylar emergency blanket and an innovative emergency tent system.
The tent is made from the same material as the blankets but formed into a different shape. It comes as a long tube with an included ridge line. This allows you to string the tent up between two points and creates a toasty space large enough for two.
Because it’s made from mylar it’s perfectly capable of keeping you warm and dry by blocking wind and rain. It also reflects up to 90% of the body’s heat, the same as an emergency blanket.
The Grizzly Gear survival blanket and Survival Tent are useful emergency gear at a good price.
Grabber Outdoors Original Space Brand All Weather Blanket
The Grabber Outdoors All Weather Blanket is a rugged survival blanket made by the original makers of the Space Brand Blanket. It’s made with laminated fibers attached to aluminized plastic to provide excellent insulation in a durable design.
The blanket measures 5’ x 7’ and is tough enough to be used as a groundcover without damage. It reflects up to 80% of the bodies heat and is totally waterproof and windproof.
Each corner has a metal grommet so you can easily run lines through the blanket. This makes it much easier to attach to trees or other points of contact to set up a makeshift tent, windbreak or fire reflector.
The Grabber Outdoors All Weather Blanket is a quality survival blanket from a good company.
UST Survival Blanket Tarp 2.0
The UST Survival Blanket Tarp 2.0 is the second generation of the company’s highly successful survival blanket. It’s made with a three-ply construction technique.
It uses one layer each of polyethylene, reinforced fabric, and metalized polyester. This gives it excellent durability but does noticeably increase its weight. The Survival Blanket 2.0 weighs 13.6 oz, substantially more than most similar survival blankets.
For that extra weight though you get a durable blanket that can double as a tarp. It has metal grommets in each corner that allow you to run a line through it.
You can throw up a basic shelter from the rain and wind in just minutes or use it as a traditional blanket. It measures 6’11” x 5’, plenty for a single person to stay warm with.
Overall the UST Survival Blanket 2.0 is a durable and highly capable survival blanket that’s great to put in your car or larger emergency kit.

Buyers Guide for Buying the Best Survival Blanket
There are only a few factors to consider when picking the best survival blanket. There isn’t a huge difference between most survival blankets, with just a few material, sizing, and price differences covering most of the market. If you don’t find what your looking for in this survival blankets guide you will find more options in out camping blankets guide.
Survival blankets are very affordable. They’re often sold in multipacks with each blanket costing barely a dollar.
There are more expensive ones, but unless you’re talking about some really next level features they rarely go above $20.
Survival blankets are made from a range of materials, with mylar being by far the most common. The original space blankets that survival blankets are based off of were made from thin sheets of mylar.
The benefit of this is mylar’s high reflectivity. Survival blankets are capable of reflecting 90% of your bodies heat, perfect for staying warm on a cold night stuck outdoors.
Nowadays these basic survival blankets have been complemented with all kinds of additional backing materials like polymers and tarp style cloth. This makes them considerably more durable but also makes them heavier.
Sizing an emergency blanket is really easy. Look for blankets that will cover you from your shoulders to your toes with several inches to spare.
Longer is definitely better in this case, with blankets of 7 feet not unheard of.
The bulk of survival blankets are made of naturally waterproof materials. They’ll work just fine wet or dry, but might not be able to keep the rain off of you.
You can wrap yourself in them poncho style or tie one up to act as a rain cover. They’re highly flexible but do have one noticeable flaw:
If you’re in a very cold climate the moisture your body releases as sweat and part of your breath can cause cause condensation to build up on the inside of the blanket. This can be a real problem if it gets on your clothes.
Wet clothes and cold temperatures are a very dangerous combination in an emergency situation.
Any survival blanket worth its salt will be windproof. Because they’re made from mylar and polymer rather than cloth they can easily be used to block the wind.
One really great way to use a spare survival blanket is as a heat reflector and windbreak for a fire. By suspending it between two or more points you can reflect the heat of the fire back at you while preventing a cold wind from blowing in.
Weight and Packed Size
Weight and packability is a major factor in choosing the best survival blanket. If you’re looking for an emergency blanket to put into a bug out bag or similar emergency kit it needs to be as lightweight and portable as possible.
Basic survival blankets weigh just an ounce or two and are about the size of a deck of cards. These will be significantly less durable than larger and heavier ones but work great as a part of a 72-hour kit.
Survival blankets by their very nature are tools of last resort. They aren’t intended to be something you use on a regular basis, and because of this they don’t need the same durability you’d expect from other outdoor gear.
Most lightweight and portable survival blankets won’t stand up to more than several uses without showing clear signs of wear. For the most part, this isn’t a big deal as they’re generally very affordable and will have served their purpose during an emergency.
If you purchase survival blankets intended for use in a vehicle or as part of a home emergency kit they’ll be more durable but noticeably heavier.
Survival blankets need to be highly reflective of heat. The vast majority reflect 80-90% of the body’s heat.
They also benefit from being visibly reflective. A bright silver or bright orange survival blanket can be used as a signalling device.
Survival blankets are inexpensive, widely available, and can save your life in an emergency.
Choosing the best survival blanket comes down to how you intend to use and store it. There are tons of great options out there at incredibly low prices.
