How to Choose the Best Sleeping Bag

The right sleeping bag varies from person to person. There are a number of factors to take into account when deciding which sleeping bag to buy, including what temperature you’ll be using it, size, price, and more.  


Sizing is really important for sleeping bags. Picking one that’s too big for you can let in cold air, whereas you’ll be uncomfortable if you choose one that’s too small.

Sizing goes beyond the overall length of a sleeping bag—the depth of a sleeping bag also matters. It is important to find the sweet spot where the inside of the sleeping bag is not too tight and not too loose.

Surprisingly, the size and the ‘tightness’ of sleeping bags also varies depending on the use. For example, the tighter a sleeping bag is, the more heat will be trapped inside. However, if it is hot outside, a cooler and lighter sleeping bag with more space can be more comfortable.


Sleeping bags vary widely in price. You can find a sleeping bag for under $100 or over $1,000. Carefully consider what features are most important to you (weight, warmth, size, etc.) and decide what you must have and what you can sacrifice to save money. 

More expensive sleeping bags tend to be lighter weight, whereas cheaper bags tend to be heavier and bulkier.


Look for a water-repellent material for your sleeping bag, which will protect you from wet ground at your campsite or unexpected rainstorms. The material can also have a big influence on the weight of the sleeping bag. 

Additional Features

There are a number of other features you might want to consider in your search for the perfect sleeping bag. Here are a few things to look for: 

  • Left or right side zipper
  • Compression ability
  • Weight
  • Hood
  • Stash pocket
  • Insulated footbox

How to Prolong the Life of Your Sleeping Bag

A well-made sleeping bag can last you for many years if you take care of it. However, if you don’t treat it correctly, it can lose its compressibility and fluffiness. 

  • Don’t store your sleeping bag compressed in the stuff sack. This can cause the fill of the sleeping bag to flatten out, and after awhile, it won’t bounce back when unrolled. 
  • Make sure your sleeping bag is completely dry before putting it away, otherwise mold can grow on it.
  • Occasionally re-treat your sleeping bag with water-repellent, as sleeping bags can lose their water-resistance over time.

How To Clean a Sleeping Bag

While there are some brands and styles of sleeping bags that can be machine washed, the best way to clean a sleeping bag is generally to hand-wash it. 

Use a bathtub, lukewarm water, and a small amount of detergent. Soak the sleeping bag in lukewarm water for about five minutes before adding the detergent. 

With your hands, scrub the water and detergent mixture into the sleeping bag, focusing on any areas with stains. Then drain the water and rinse out the detergent, squeezing the sleeping bag until the water runs clear. 

If you have a drying rack, hang your sleeping bag to dry. While drying machines can dry your sleeping bag in no time, the heat will damage the material.
