Best Sleeping Bags

When you go on a trek or camp for several days, making sure you get a good night’s sleep is essential to be active the next day. Before planning your next outings, you should think about your sleeping bags.

How to Choose Your Sleeping Bag?

When it comes to choosing a sleeping bag for various adventures, there are several important factors to consider. Here is a comprehensive buying guide to help you make an informed decision:

The Materials

Most sleeping bags are made of polyester. On the other hand, not all are padded, so it is important to have this notion because a padded sleeping bag will retain heat better than an unpadded bag.

The Size

Sleeping bags are designed to allow the majority of people to fit inside with an average length of 190cm. On the other hand, if you are taller, it becomes essential to move towards an XXL format of more than 200 cm.

Note that there are also two-seater sleeping bags.

The Packed Size

The packed size is also very important. The size of your sleeping bag should not be too bulky so that you can easily transport it. It should easily fit in your hiking bag.

The Weight

Weight is also a selection criterion you can’t ignore. Indeed, it must be as light as possible to facilitate its transport while ensuring good heat retention. In most of the sleeping bags on the market, the average weight varies from 2.2 pounds to 5.5 pounds. So make a choice according to your needs. For example, for ultralight backpacking, you should choose a minimum-weight model.

Temperature Rating

The comfort temperature is the average temperature to fully enjoy your hiking sleeping bag. Nevertheless, the point that we find most important is knowing the maximum outside temperature that your sleeping bag can compensate for. If it is -3° and your sleeping bag is not made to withstand this temperature, the night will be cold.

The Closure System of the Mummy-Type Sleeping Bag

This is an important element to take into account in the thermal protection of the sleeping bag to prevent heat loss and cold air infiltration into the bag.

  • At the hood only: All mummy-type bags have a drawstring at the hood to adjust the opening and leave only a small part of the face exposed.
  • With an inner flange: A collar (replaced by a bead on some bags) insulates the body at the torso and provides additional comfort by keeping the hood open while retaining body heat in the bag.


Different sleeping bags are designed for different seasons.

  • Summer Bags: Lightweight and usually have higher temperature ratings.
  • 3-Season Bags: Suitable for spring, summer, and fall. They offer a balance between warmth and weight.
  • Winter Bags: Insulated for colder temperatures and have lower temperature ratings.

Insulation Types

  • Down: Offers excellent warmth-to-weight ratio, but loses insulation properties when wet.
  • Synthetic: Performs better in damp conditions and dries quickly, but is generally heavier and bulkier.

Zipper Type and Location

Look for high-quality zippers, especially if you plan on using the sleeping bag frequently. Side zippers are common, but some bags also have zippers at the foot to allow for ventilation. Consider if you want a full-length zipper or a partial one.

The Color

The color has no functional interest. It is a choice of the heart. The editorial staff prefers hiking and camping accessories in black or khaki. But hey, tastes and colors are unique to everyone.

The Price

Although the camping sleeping bag is not the biggest investment for the camper and hiker, do not hesitate to spend a little more to increase your comfort. However, if you have a limited budget, you can visit our details guide on the best cheapest sleeping bags under $100 available on the market.

A hiker who has slept badly is an embittered hiker.

How do I choose the right size of sleeping bag?
