When you’re out in the field, hiking, camping, hunting, or trekking, there’s one piece of kit that’s more essential than any other: a survival sleeping bag.
With a range of options available at the market at varying price points and qualities, today we’re going to help you to know what to look for when researching the best survival sleeping bag for you.
Before we talk about what makes the best survival sleeping bags and where you can find them, let’s talk a little bit about what a survival sleeping bag is. A survival sleeping bag is a lightweight, compact piece of kit designed to save your life in a survival situation.
The keyword here is survival, these are not sleeping bags rated for comfort, but their ability to keep you warm enough when off-grid in an emergency survival situation, and prevent the onset of hyperthermia.
Typically constructed from a single sheet of thin and lightweight reflective material, the idea of a survival sleeping bag is to reflect the user’s body heat back and prevent it from escaping.
This means when using one, you can slowly let your own body heat build-up within the bag and form a protective shield of lasting heat around your body.
There are a few key factors to look out for when it comes to survival sleeping bags. First up and most importantly, how well does it reflect your heat?
We call this a survival sleeping bag or blankets reflective body heat value, and a good survival sleeping bag should reflect at least 80% of your body heat back at you.
Weather resistance; also important is a survival sleeping bag’s weather resistance, that’s water, wind, and snow.
Survival sleeping bags are usually made from a water-resistant and wind-resistant polyester material, meaning they can often be useful for shelters as well as sleeping bags.
Functionality; the best survival sleeping bags on the market come with multiple configurations and functions, some come as blankets that can be used as a sleeping bag, but also as a tarp for a rain cover to protect your camp or gear, some can be set up for use as a bivvy style shelter, and some can be used as all three.
Durability and quality; another key factor when choosing your survival sleeping bag is how well it’s going to fare in the field.
An emergency sleeping bag that rips as you open it is going to be of no use when it comes to any life-saving scenarios.
But the best survival sleeping bags come with super-strong polymerized material that can withstand tears and punctures, meaning they can be reused and massively increase their dependability in a survival situation.
Additional features; look for extra features when searching for the best survival sleeping bag for you.
Some come with little stuff sacks, making them great for using again and again, whilst always keeping them safe and protected in your pack.
Some have whistles on the drawstring of such sacks, innovative addition to such a life-saving piece of kit.
And some come equipped with paracord for use as a shelter, or even grommets in the corners, making them much more versatile options when it comes to configuring different types of shelters.
So with all that in mind for what you need to look for when deciding which survival sleeping bag is best for you, let’s jump straight into it, here’s our best survival sleeping bags, reviews, and comparisons.

What we don’t like about the Nano Heat Blanket from AMK
This product is a single sheet of reflective and waterproof material, meaning it doesn’t have a tube design or can be zipped up to make a true sleeping bag.
This means whilst it will hold up in a survival situation, a lot more heat will escape your body than if it had a sleeping bag style design
- Super lightweight and compact, the Nano Heat Blanket is perfect for a bug-out bag or survival kit in your car.
- Comes with a durable waterproof coating and the blanket is windproof so will protect you from the elements.
- One of the lightest survival sleeping bags on our list.
- Its waterproofness comes down to a durable coating on the surface of the material, rather than the material itself. Though AMK claims it can be used again and again, this may not stand the test of time as well as some of the other survival sleeping bags on our list.
- Can be used as a survival sleeping bag though no tube design so will be a lot harder to get meaningful rest and ensure it’s wrapped around your whole body to retain body heat efficiently.

What we like about the TACT Bivvy Emergency Blanket from Survival Frog
We especially love the TACT Bivvy’s tube design, making it a true survival sleeping bag and making you better equipped against the elements in a survival situation.
When it comes to retaining as much of your body heat as possible, sitting or lying in a bag of reflective material is far better than sitting under a blanket.
You’ll be a lot more efficient at keeping that all-important heat in, which is how the TACT Bivvy can boast a 90% reflective body heat value.
What we don’t like about the TACT Bivvy Emergency Blanket from Survival Frog
Unfortunately, the TACT Bivvy Emergency Blanket from Survival Frog doesn’t support a configuration as a shelter, you could use it as a tarp for a makeshift shelter in a survival situation, but its narrower design on account of its tube shape means it won’t be sheltering a very large area.
- One of the smallest and lightest survival sleeping bags on our list, though still unpacking to 7 feet in length.
- Comes with a drawstring stuff sack and survival whistle.
- Tube design, so much more practical and efficient as a survival sleeping bag.
- Smallest and lightest on our list, great for ultralight backpacking.
- Available in tactical orange or green.
- Designed as a survival sleeping bag, but only as a sleeping bag, and lacks features for additional functionality that could make it useful as a shelter.
- The green version will be less visible for rescue teams in a survival situation, though being less conspicuous makes it more suitable for stealth camping.
- Waterproof and windproof material protects you from high winds and the harshest outdoor elements

- Reusable emergency blanket is durable enough for multiple adventures folds up for compact storage

Next up on our list is the most versatile and heavy-duty survival sleeping bag we’ve found. The Sport Utility Blanket from Survive Outdoors Longer is a marvel of engineering.
It’s made from a single layer of woven polyethylene, rather than several layers of weaker materials sandwiched together.
This makes the Sport Utility Blanket a survival sleeping bag that’s designed to last. Though it’s a blanket rather than a tube design or true sleeping bag, the Sport Utility Blanket from Survive Outdoors Longer is more than big enough to be suitable as a sleeping bag or configured as several types of shelter.
What’s more, the Sport Utility Blanket from Survive Outdoors Longer boats a 95% reflective body heat value, the highest on our list, and as far as we’ve been able to find, the highest on the market, meaning this survival sleeping bag is a truly lifesaving addition to your kit bag for survival situations where it’s your own body heat that’s going to mean the difference in waking up in the morning.
- 95% reflective body heat value
- 6 grommets for use as an A-frame tent, bivvy style shelter, ground sheet and tube tent
- Waterproof and windproof
- Rugged design so can be used again and again without being damaged
- Compact and lightweight
- Tear and puncture resistant
- Weighs 311g
What we like about the Survive Outdoors Longer Sport Utility Blanket
It has to be said, the Sport Utility Blanket from Survive Outdoors Longer is truly heat-reflective with a massive 95% reflective body heat value. This is the highest available on the market so the blanket is sure to keep you warm in a survival situation.
But best of all we like the addition of its 6 grommets for use as various types of shelters. This feature is the Sport Utility Blankets secret weapon and sets it aside from most others on our list.
Others we have reviewed can be configured as shelters, but none as effective and diverse as the Sport Utility Blanket from Survive Outdoors Longer.
The blanket can easily be set up as an A-frame tent or tube tent, as well as a bivvy style tent to wrap yourself up on the floor and seal that all-important body heat in.
What we don’t like about the Survive Outdoors Longer Sport Utility Blanket
While the Sport Utility Blanket can be used as a survival sleeping bag, it’s designed as a blanket and not a bag. This lack of a tube-style design means it will be less efficient at keeping your body heat in and around your body, though its large size and heavy-duty construction will certainly make it easier to get the most out of its 95% reflective body heat value.
Also, it doesn’t come with a stuff sack, unfortunately, meaning though it’s designed for use, again and again, it’s not going to be as convenient for putting away and keeping in your pack as many of the others on our list.
- Highest reflective body heat value of any survival sleeping bag on our list.
- Strongest on our list of survival sleeping bags with the most heavy duty material used making it ideal for repeated use and able to be a permanent addition to your bug out bag or emergency preparedness kit.
- It’s orange design will make it highly conspicuous for search and rescue teams in a survival situation.
- Additional features of grommets make it the most versatile survival sleeping bag on our list.
- Lacks a stuff sack which is going to be inconvenient for packing away and keeping as small as possible when not in use.
- Not a true sleeping bag design, as it is designed as a blanket, not a survival sleeping bag, though can be used as a survival sleeping bag.
- Though the Sport Utility Blanket is still a lightweight and compact bit of kit, it comes in as the heaviest on our list at 311g.
- Strong, metallised polyester materials
- Windproof & waterproof
- Radar reflective
Rounding up our list we get to our final product, the Thermal Blanket by Lifesystems.
Reflecting and retaining up to 80% of body heat, Lifesystems Thermal Blanket has been designed for all survival search and rescue operations in mind.
Its compact and lightweight structure brings it in at a solid middle ground to the products we’ve reviewed on our list.
The blanket can be used as a survival sleeping bag, though it is a blanket design and not a tube design.
Made of a strong, metalized polyester material, the Thermal Blanket from Lifesystems is windproof and rainproof, making it more than adequate protection against the elements should you be caught in extreme wind, rain, or snow.
- 80% reflective body heat value
- Wind and waterproof
- Packs down to a compact and lightweight size
- Vivid orange colour mean it is visible for search and rescue teams
- Recommended kit by D of E
- Weighs 220g
What we like about Lifesystems Thermal Blanket
The Thermal Blanket from Lifesystems sports a size large enough to wrap around the entire body and tuck everything in, making it useful as a survival sleeping bag, and though it has one of the lowest reflective body heat values on our list, 80% efficiency still makes it a lifesaving bit of kit in a survival scenario.
But what makes Lifesystems Thermal Blanket so great is its low price point.
What we don’t like about Lifesystems Thermal Blanket
Its lack of a tube design and low reflective body heat value is going to mean the Thermal Blanket from Lifesystems is one of the least effective survival sleeping bags on our list at keeping you warm.
The Thermal Blanket comes without a stuff sack and though it is made of strong material, Lifesystems does not specify it being tear and puncture resistant, meaning it is one of the least durable blankets on our list.
However, in a survival situation, this life-saving technology could really be the difference between life and death.
- Lightweight at 220g, the Thermal Blanket from Lifesystems is a compact and small addition to your bug-out bag or hiking gear.
- Its bold use of orange colour and silver branding make it stand out from a distance and will assist in search and rescue operations.
- Being weather resistant, the Thermal Blanket from Lifesystems will protect you against wind rain and snow.
- By far the cheapest on our list.
- One of the lower reflective body heat values on our list of survival sleeping bags.
- Comes without a stuff sack, or any additions for use as a shelter like grommets or paracord, the Thermal Blanket by Lifesystems has been designed as a minimal blanket or sleeping bag.
- Repeated use is supported but likely not facilitated well by Lifesystems choice of material and lack of stuff sack, though the blanket is designed for repeated use.
- Not a tube-style design so less effective as a sleeping bag, but its large folded-out size makes it effective as a survival sleeping bag in an emergency situation.
So overall it’s the Life Tent Survival Shelter by Go Time Gear that takes the top spot on our list of survival sleeping bags.
We loved its multifunction design as a tube tent, shelter, or survival sleeping bag, and its additional features of a waterproof stuff sack and survival whistle make it one of the most reliable survival sleeping bags we’ve found.
This is a truly lifesaving piece of kit to put in your emergency preparedness bags, bug-out bags, or to keep on hand in the back of the car for whenever that emergency situation arises.
Thank you for reading our Best Survival Sleeping Bag and remember, any emergency blanket or survival sleeping bag is better than nothing and will make a huge difference to your chances of survival in an emergency situation. Build shelter, wrap up warm and conserve energy until the danger has passed.
