Sleeping Bags: A Buying Guide – How to Choose Sleeping Bags

A good night’s sleep is an important experience after doing outdoors for hours. Here is the time when you need to use your comfortable sleeping bags.

The sleeping bags for the backpackers come with different models, sizes, and price range you can choose from your favorite brands. When you browse around on the net, there will be tons of models that you come across. So, how to pick the right one?

Here are the factors to think about to find the best sleeping bags on your part.

Your budget

Your budget arrangement is the first and foremost factor that you need to count in. After budgeting, you will be able to narrow down the list to your preferred budget ranges.

Focus on a trustworthy, reputable, and reliable brand

On most occasions, the chances will be much greater if you are focusing your search on the best brands. In terms of sleeping bags, there are some brands that you could focus on such as MEC, Big Agnes, Therm-a-rest, Sierra Designs, and Western Mountaineering.

How cold your destination is

Where will you camp? Is it colder or hotter? Anyway, the right temperature is needed to make your convenient and comfortable. Therefore, you will want to check the temperature ratings on the models you are scouting. The temperature ratings come with the measurement of the lowest temperature that the bag can bare to preserve the warmth for the users. The temperature ratings will give you the idea about the level of warmth that you will get from the particular sleeping bags when you are sleeping out there.

The shapes of the sleeping bag

There are three main types of sleeping bags: rectangular, barrel, and mummy. The rectangular sleeping bag comes with the boxy design. These models tend to be spacious and roomy. It is also affordable to attain. But if a high level of warmth is what you’re after, this model won’t give you much. It is best for hotter temperatures.

Barrel type, on the other hand, provides a a better level of warmth. Some barrel sleeping bags from different brands also come with an extra hood to maximize the overall temperature. It is less roomy than rectangular bags but best for three-season use.

If you are after the four-season sleeping bag, then you will want to choose mummy bags instead. As the name suggests, the shapes of these sleeping bags are like a mummy. The part of the sleeping bag is all integrated, including the hood. You need to enter your body to the mummy bags. These provide the best level of warmth compared to other sleeping bags in our list. You can use these for three-season, as well as colder months including winter.


If the space is sacred for you, then you will want to choose the Quilts type of sleeping bag. Quilts designs are very close to the blankets without any insulation. These designs allow you to add a sleeping pad underneath the bag. These are lightweight and compact, and you can store these to your backpack easily.

The sizes and weight of the sleeping bag

The sleeping bag sizes are different to match the height of the users. It is important to choose the right size of the sleeping bag. If you are choosing longer sized sleeping bags, it does not merely mean that you attain extra values from your money.

Here is the thing. If the sleeping bag is much longer than you need, there will be extra space where the heat won’t be maximally absorbed. As a result, you will feel colder. The fitter your sleeping bags, the more maximized the warmth distribution will be. When shopping around, be sure to check the exact dimensions of the sleeping bags and choose the right one for you. If it is for your kids, it doesn’t hurt to measure them first then fitting.

Weight is another factor. It will determine how light or heavy your travel will be. The success key to finding the right weight off the sleeping bags is to compare the bags with the same temperature rating. For instance, if the temperature ratings of two compared products are both “6”. Then you will want to compare the weight. Let’s say A is lighter than B. You would likely choose the sleeping bags. But make sure that the weight is the “sleeping bag” only. Don’t include the accessories.

There you have them! These simple tips will surely help you a lot in determining the sleeping bags for your upcoming adventure. Good luck!
