How to choose the best sleeping bag?


Your sleeping bag will probably be one of the most expensive items in your backpack, apart from tents, so by choosing a good one, it can easily become your favorite piece of gear.

Budget sleeping bags are in the $150 – $200 range and high-end sleeping bags can easily top $500.


Sleeping bags are one of the four heaviest items in your backpack – among tents, backpacks and sleeping pads.

Bags that are ultralight are great for backpacking. They are costly since they are made of high quality delicate materials to cut down weight. Also, by going for ultralight options, you might be compromising on something – be it warmth, safety or comfort.

So it’s critical to strike a balance between all of them.

If you aren’t too keen on ultralight options, lightweight bags that are a good mix of features & weight solve the purpose.

Since this article focuses on sleeping bags for cold weathers, warmth has been our primary consideration followed by weight.


Sleeping bags don’t generate warmth, your body does. The bags trap the heat from your body from getting out, thus keeping you warm.

Sleeping bags that are better insulated, trap more heat, and keep you warmer. That’s also one of the reasons Mummy bags are cozier and warmer than quilts. Quilts have a large area and since the heat spreads across it, it doesn’t keep you as warm.

Fit – Mummy bags or Quilts?

Mummy bags

  1. Keep you cozy & warm
  2. Come with & without hoods
  3. Best for cold weathers
  4. Restricting space
  5. Zipper can be snaggy at times


  1. Less restrictive
  2. Less warmer
  3. No zipper issues
  4. Less bulkier comparatively
  5. Does not come with hoods
  6. Cheaper

Fill material – Down or Synthetics?

Bags with a down insulation have an excellent weight-to-warmth ratio and compress more easily. For anyone who is going to backpack, down is the best choice.

Synthetic sleeping bags on the other hand, are bulkier and cheaper. They perform slightly better than down bags when wet by retaining heat more. It might be a good choice for car camping.

Temperature Ratings

This is explained in the below section.

Are temperature ratings real?

EN Ratings

European Norm (EN) is to standardize the temperature ratings of sleeping bags. It keeps ratings consistent across the industry, but not all companies use EN ratings.

The EN Rating specifies 4 limits according to gender, but the most common one is the EN Lower Limit. It’s defined as the temperature at which a standard male can sleep for eight hours in a curled position without waking.

Fancy terms to standardize temperatures, but how do they translate to us?

What does a sleeping bag with a lower limit of 20F mean?

In simple terms, it means that it keeps you alive till 20F, and not that you’d be warm at 20F. So, there’s no exact science of choosing a temperature rating.

The rule of the thumb, to go by here is to choose a sleeping bag that’s warmer than you want it to be at the campsite.

Increasing the temperature rating

While it’s true that choosing the temperature rating isn’t always accurate, always know that you can increase the warmth of the sleeping bag by using a sleeping pad, jackets and liners, etc.

If you know you’d be in for a cold night, carry one of them to increase the warmth.

While it’s wise to go with bags with EN ratings, cheap bags may advertise temperature ratings lesser than what they actually withstand. So it’s crucial to invest in a good quality sleeping bag.

What’s the best way to use Sleeping bags

Sleeping bag liner

Consider using a liner on the sleeping bag, of any material say cotton, polyester, silk, etc. Anything thin & lightweight will do.

This ensures that the sleeping bags don’t get dirty because now there’s a barrier in between.

Air out the Bags

During the camp, make sure to air out the bag once a day. It dries out the moisture if any.

Make sure it’s not exposed to harsh sun as it might damage the outer layer of the sleeping bag. Mild sunlights work best.

Handling zippers

This may seem a trivial aspect but if it snaps, it might ruin a night’s sleep and make the bag unusable. Not every sleeping bag comes with high quality zippers, and if handled hastily & roughly, they tent to snap.

Gentle care

Be conscious when you take the sleeping bag near fire, a campfire for example. Make sure kids don’t jump on the bags, it might cause the down material to get distributed unevenly inside the bag. That makes it difficult to sleep on it.

Handling it with a little extra care makes the sleeping bag durable for a long time.

Store it when dry

Make sure the sleeping bag has dried well before you store it in a compression bag. Even a little bit of moistness in the bag will damage the material, and also cause bad odors.
