Military sleeping bags are intended to be durable, versatile and most importantly, warm. They vary in their materials, shapes and temperature ratings, so finding the right one for you depends on different factors. If it’s a cost-effective option for subzero temperatures you’re looking for, the U.S. Military Modular Sleep System is the top option. 

What to know before you buy a military sleeping bag


Think about the activity you’ll be doing that requires a sleeping bag, whether it’s camping or backpacking. There’s no sense in lugging a weighted sleeping bag designed to handle sub-zero temperatures if you’re only using it on slightly chilly or warm nights. Consider the environments you plan on using it in the most before deciding on a purchase to ensure the maximum amount of use.

Weather conditions

Mountains, deserts and beaches are all unique environments with their own weather conditions. Some military bags are constructed of water-resistant materials to keep out moisture and make rainy nights manageable. Consider which weather conditions you will likely encounter.


Weight and size affect how you transport and store a military sleeping bag. Usually, space is very limited when backpacking or camping. If the military sleeping bag is designed to handle sub-zero temperatures it typically is heavier and bulkier. A more versatile military sleeping bag typically is lighter and more portable.

What to look for in a quality military sleeping bag


Polyester, cotton and nylon are common materials used to construct military sleeping bags. They are designed to be durable while trapping one’s body heat for a warm night’s sleep. If you intend on sleeping in extreme conditions such as on a snowy mountaintop or in sub-zero temperatures, consider down filling.


Your military sleeping bag should be a snug fit to limit any air pockets that let precious heat escape or cold air to get in. Factor in your body type to achieve a proper fit. The mummy shape is a popular design because it’s cone shape becomes tighter around the legs and feet.

Temperature rating 

Arguably the most important feature to look for when purchasing a military sleeping bag is it’s temperature rating. This tells you the lowest temperature the sleeping bag is designed to handle that will keep you warm. They are usually listed in the product descriptions.

How much you can expect to spend on a military sleeping bag

Price typically depends on the materials it’s made from and its temperature rating. Most often, military sleeping bags range in price from $149.99-$365.
