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

Tact Bivvy Emergency Shelter

Buy from Amazon

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.

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.

Price

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.

Material

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.

Length

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.

Waterproofing

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:

Breathability

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.

Windproofing

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.

Durability

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.

Reflective

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.

Final Thoughts

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.
