7 Best Emergency Sleeping Bags for When You Really Need One

Hiking and backpacking through remote areas help travelers explore unseen regions. Beautiful waterfalls, stunning cliffside views, and jungle canopies greet these adventurers. But with every expedition comes risks. Hopefully, you plan and take precautions. However, sometimes you experience circumstances out of your control. This is when a survival kit with an emergency sleeping bag is crucial.

What is an emergency sleeping bag? Let’s explore this essential item and look at seven of the best options!

What Is an Emergency Sleeping Bag? 

An emergency sleeping bag is one you use only for emergencies. This is not a sleeping bag you’ll typically use when setting up camp. There are more comfortable options for tent camping. You’ll use an emergency sleeping bag for shelter or protection in unplanned situations.

When Do You Need One?

Hopefully, you’ll never need an emergency sleeping bag. However, it’s best to have one on hand. Travelers can be stranded during snowstorms. Having an emergency blanket in the glove compartment of your car ensures that you have protection if you spend hours in your car waiting on first responders.

Whenever you venture into the wilderness or go backcountry camping, you risk encountering dangerous conditions. Sometimes it’s the weather like wind, snow, or rain. Other times you might get injured and have to wait on help to arrive. A response could take hours, and if you spend the night in a desert area, temperatures may be hot during the day but can drop below freezing at night.

Are Emergency Sleeping Bags Reusable? 

Although almost all emergency sleeping bags will say “reusable,” some are impossible to get back into their small carrying bag. Depending on how well you can refold the blanket, you might use it again. You can count on its durability. It won’t tear or get weather damage. So if you can get it back in the bag, it will be good to go the next time you use it.

Are Emergency Sleeping Bags Warm? 

Most emergency sleeping bags retain 90% of your body heat. They aren’t insulated but include materials that keep your body heat inside the bag to protect you from cold temperatures. Many have ratings for extremely low temperatures to keep you safe in worst-case scenarios.
