Finding an emergency bag shouldn’t be difficult since there are tons of them on the market. However, not all sleeping bags will work for every situation. For example, you don’t want to use a regular sleeping bag when faced with a survival situation where you may be vulnerable to hypothermia or a lot of moisture in a colder environment.

This guide will show you the best options for survival situations. But first, let’s set the ball rolling with factors to consider when choosing the best emergency sleeping bag.

How to Choose an Emergency Sleeping Bag – Buyer’s Guide


There are different emergencies where a sleeping bag will be necessary. The type of bag you choose will depend on the situation you are preparing for.

Are you in the market for something that will come in handy if your car breaks down in the middle of nowhere? Or are you prepping for a situation where you may have to bug out unexpectedly? Perhaps you want a sleeping bag for your at-home emergency kit when the power goes out, and you need to stay warm.

It will be easier to narrow your choices when you figure out the purpose of getting a sleeping bag.

Temperature Rating

Think about the average temperature of where you live before choosing an emergency bag.

Sleeping bags with temperature ratings of -40oF to +4oF are ideal for extremely cold conditions, such as ice or snow. Also, this type of bag will do for mountaineering expeditions.

The recommended temperature rating for warm weather or summertime is anything from +30oF and above. Consider ratings between +5oF to +29oF for a varied climate.


Sleeping bags that are too big or small for you won’t do much good, no matter the quality. Sleeping bags that fit your body traps heat better, and one with plenty of space causes heat to escape.

Choose an emergency sleeping bag that is snug yet with enough room to allow air pockets for proper insulation. Double-check the measurements on the sleeping bag to make sure it’s the right height and size before making a purchase.

The 10 Best Emergency Sleeping Bags for Survival


Sleeping bags come in rectangular, double bag, and mummy shapes. These all have situations where they shine, but a mummy shape is an ideal choice for survival. It will trap body heat better than a rectangle or double bag shape.


Another crucial consideration is the type of fill. A bag’s fill traps body heat and insulates you from the cold environment. Your choices include down (natural) and synthetic fills.

Good quality down offers the most insulation and is the preferred choice if you plan to spend the night out in very cold weather. It is durable, has remarkable compressibility, and has the best warmth-to-weight ratio.

However, down fill needs to be fluffed and is a poor choice for damp conditions. Also, it can be quite expensive and not exactly easy to care for. It can lose most of its insulation if it gets wet.

On the other hand, synthetic fill is easier to clean, more affordable, offers insulation even when wet, and is less expensive. Consider an emergency sleeping bag with synthetic fill for your car emergency kit or bug-out bag kit.

The downsides to this survival sleeping bag option are poor warmth-to-weight ratio, shorter lifespan, and heavier weight.

Now let’s take a closer look at some of the best emergency sleeping bags for survival. These sleeping bags will make a great addition to your survival gear kit.
