Things to consider before buying a sleeping bag

Let’s consider the things that you should not miss while buying a sleeping bag.


Warmth is one primary component that you should keep in check before choosing your sleeping bag. The heat of a bag is usually derived from the amount of insulation a bag has. Generally speaking, more volume of insulation equals more warmth.

Another thing that determines the warmth of a sleeping bag is its fill power. The fill power is the indicator of how well a sleeping bag can loft. If your sleeping bag has a higher fill power, it will have a higher loft and can be lighter than the rest thus providing extreme warmth.

Temperature Ratings

Backpacking sleeping bags typically contain a three-season feature and range between 10 and 32 degree Fahrenheit in temperature. Each bag has a temperature gauge. The comfort level is vital as this tells you how cool it can be before you start to feel cold. The lower the temperature of a sleeping bag, the better it can serve you.

Usually, the standard temperature ratings of a sleeping bag depend on these guidelines:

Upper Limit: This is a highest temperature at which a standard adult size person could have a comfortable night without excessive sweating.

Comfort: This is a temperature at which a standard adult size person can land a comfortable sleep in an enjoyable position.

Lower Limit: This is a temperature at which a standard adult size person can sleep for eight hours in a curled position without any constraints.

Extreme: This is a minimum temperature at which an adult size person can contain for six hours without risking death from hypothermia.

Weight and Packability

Given that you will be carrying your bag, the weight of your sleeping bag could determine the pace of your movement during your trip. The weight of a bag depends on a few things:

  • Insulation weight
  • Shell type
  • Additional features

Note that higher fill power insulation occupies the same space with less weight than the insulation with lower fill power.

Note that lower fill power insulation occupies more space and weight than higher fill power insulation.

Also, the weight of the sleeping bag is reduced if it has thinly cut shell fabrics.

Also another thing to consider is whether or not the sleeping bag can be packed in your luggage. Your sleeping bag needs to ideally fit in your backpack with all the other backpacking gear that you might be carrying during your trip.

If you are planning a long trip, you have to get a lightweight, or else it will put too much burden on your shoulders.

Level of comfort

If you are a regular trekker, you probably know how important is it to determine the comfort of a sleeping bag before adding it in your accessories. Almost every adventurer eyes a better performing sleeping bag over everything else during a trip to the wilderness.

A comfort level of the sleeping bag can be determined by how well it is structured and design.

Bags with the extended internal dimensions would allow you to move freely as there would be enough space to control your movement. However, the spacious bag comes with the drawback of less warmth. Moreover, if added more material to maintain its warmth, it will go on to become heavier.

Features and Cost

Every bag has a unique feature and design. In general, the sleeping bag comes with shell fabric, zippers, draft tubes, neck baffles, and hood design. Meanwhile, the inclusion of extra features like storage and compression sacks could result in the bag being costly ( and heavy).

Some bags comes with additional feature of attached torched or built-in mosquito net. These features will serve you well, but it will increase the price tag.

The kind of bag you want should be determined by the type of your trip. A trip to the alps or the himalayas, for instance, would require you to buy a sleeping bag made with study material that can protect you from the cold.

Types of Sleeping Bag

Generally, there are three different types of sleeping bag available for your consideration:

Summer Bags

Summer sleeping bags are designed for 32 degree Fahrenheit or higher temperature ratings. These bags do not have the built-in hoods to keep you warm in colder temperatures. They tend to serve you well in 40 to 50 degree Fahrenheit.

Three-Season Bags

These bags are considered versatile for hiking and adventuring. The temperature ratings of these bags range from 10 degree Fahrenheit to 32 degree Fahrenheit to help you become comfortable in external temperature of 20 degree Fahrenheit. Three-season sleeping bags would perfectly suit you for spring and fall outings as well as summer vacation in the high mountains. The bags with the extra features of draft collars and zipper draft tubes are considered as good three-season bags.

Winter Bags

These sleeping bags are crafted for camping during extreme temperatures. Winter bags are good for about 20 degree Fahrenheit and below temperature ratings. These bags come with all the feature of a three season sleeping bag, along with extra insulation.

Insulation (Down vs. Synthetic)

Since the type of insulation directly affects the warmth-to-weight ratio of sleeping bags, it is one of the most critical choices to make while selecting a model.

Let’s look at the different type of insulation in more detail:

Down insulation

Down insulation is a touch too expensive but it comes with a better warmth-to-weight ratio. The price of the down insulation generally depends on fill power which ranges from about 600 to 900. Note that a bag with high-quality insulation keeps it lighter than a bag with synthetic insulation of the same temperature rating. It also aids in better compressibility.

Synthetic Insulation

Synthetic insulation is perfect for an outing in the wet condition. The availability of fluffy polyester material prevents the absorption of water. The bags with synthetic insulation do tend to be cheaper than down bags but also weigh more in comparison to down insulation. This type is not suited for long trips.

Quilt Vs Mummy Bags

The shape of a sleeping bag is designed by keeping in mind the different level of comfort designed by campers.


With excellent warmth to weight ratio, down quilts have gained massive popularity. This has been possible by cutting out the material for insulation. Quilt bags also act as a simple blanket with the addition of a top cinch cord. The cord can be closed to seal out the cold around neck and shoulders. You should take note that since the quilts don’t have any hoods, it is vital for you to pack a warm hat or hooded clothing to avoid chilly evenings. These bags serve well when the temperatures are above 32 degree Fahrenheit.


Mummy bags are excellent for cold, windy and unpredictable climate conditions. These bags get maximum thermal efficiency because of the tapered cut style that passes through the legs and feet. Mummy bags have a primary purpose of containing the heat your body generates which is more efficient in smaller interior space. The primary benefit of mummy bags is that they contain less material and insulation thus resulting in its light weight and great packability. These bags work well when the temperatures dip below 32 degree Fahrenheit.

To conclude

Different kind of sleeping bags are designed for specific purposes. Hence you need to have some inkling of the kind of trip you are making before deciding on a sleeping bag.

If you are going for a long hiking trip choosing a lightweight is a must. For a short trip to the backcountry, weight will not be a factor.

Best of luck with your shopping. Let us know how your trip went.
