If you are a camping enthusiast, then a sleeping bag for cold weather will come in handy. With the number of campers increasing by the day, there has been an influx of camping essentials in the market. Are you struggling to find the right cold-weather sleeping bag? Here is what you should consider before making a purchase. 


Temperature Ratings

Temperature ratings indicate the coldest condition that you can be comfortable in the sleeping bag. These ratings are crucial, especially if you are going for your first winter camping trip. For instance, assuming the comfort level of your sleeping bag is 20 degrees. You will be able to sleep well at 20 or more degrees.

Apart from wearing warm clothing, use an excellent quality sleeping pad beneath. Remember, temperature ratings vary depending on your camping location. The sleeping bag you choose should come with EN standard certification and an EN13537 mark. These markings mean that the sleeping bag has gone through a thermal manikin test. This test is more authentic than an independent test done by the manufacturer. There are four standard temperature ratings to ensure you are comfortably warm. These are:

·       Upper Limit

Under this rating, a male should be able to sleep comfortably without sweating. They can even keep their arms outside the sleeping bag, and open both the zipper and hood.  

·       Lower Limit

Under this rating, a male should be able to sleep in a curled position for 8 hours uninterrupted.

·       Comfort

Under the comfort rating, a female should be able to sleep in a relaxed position comfortably. 

·       Extreme

This rating defines the minimum temperature that a female can sleep for up to 6 hours without risking hypothermia.

It is worth mentioning that sleeping bags that feature an EN standard tag are more costly. Further, no level of testing can be wholly perfect for you because different people feel cold differently. Consider layering your clothes and only take off the layers one after the other if you feel too hot. You can also pile up the layers if the temperatures drop and zip up your sleeping bag. 

Insulation Material

Sleeping bags are made of different types of insulation material, and each comes with pros and cons. Some of the commonly used insulation materials include:

·       Synthetic

Synthetic-insulation-made from-polyester

Synthetic insulation, made from polyester, is a cost-friendly way of keeping you warm. Sleeping bags for cold weather made with synthetic insulation operate well even during damp weather. They are also hypoallergenic and durable. However, transporting synthetic-insulated sleeping bags can be difficult because they are bulky and hard to pack down inside their storage sack.  

·       Goose-Down

While goose down sleeping bags can be pricey, many campers prefer them because they are durable and warmer than synthetic sleeping bags. You can compress them to form a small pack. However, they lose their insulating capability once they get wet. 

·       Water-Resistant Down

Water-resistant down sleeping bags are treated to shield the feathers from moisture. These sleeping bags are some of the most expensive options available. However, they are portable and remain warm even when they become damp. 

·       Zippers

The sleeping bag you choose should be easy to unzip because you will be entering and exiting it often. Opt for sleeping bags that come with long length zippers that open on both sides. These offer more flexibility and ventilation.

Some cold weather sleeping bags come with short zipper lengths that make them ultralight. However, sleeping in them could make you feel constricted and uncomfortable. Avoid metal zippers because they can be unreliable, delicate, and heavy.

Plastic and nylon zippers are ideal when it comes to their length, quality, and ability to adapt to varying weather conditions. Slider zippers, on the other hand, come with non-locking and double pulls features. You can open them both from the external and internal parts and this makes the sleeping bag easily accessible.

·       Zipperless Sleeping Bags for Cold Weather

Today, some of the lightest sleeping bags are zipperless, which makes them easy to open and close. Apart from adding weight to your sleeping bag, zippers become worn out over time. If you opt for a zipperless sleeping bag, ensure it features a draft tube.  

The Fit


Your sleeping bag’s shape and size determines how effective it will be. The right sleeping bag should be form-fitting. If it is too big, then it will not insulate you appropriately. Again, you do not want a small sleeping bag.

Apart from making you feel uncomfortable, it will be a snag for the perfect warmth. Sleeping bags come in various shapes, with the most common being rectangular and mummy. A rectangular sleeping bag is ideal for regular weather patterns. Mummy bags, on the other hand, shield you from the heat during overly cold temperatures.

Many sleeping bags for cold weather come in the mummy shape. Rectangular bags offer more room to move around, but mummy bags give you better insulation. The enhanced insulation prevents heat loss through the head.

Many mummy sleeping bags for cold weather also feature drawstrings around the hood. Be on the lookout for other features like neck mufflers or draft collars and face mufflers. These features help protect your head and neck from the cold. 

Spacious Interior


While a figure-hugging sleeping bag is warmer, it reduces air space over your body. Spacious cold weather sleeping bags, on the other hand, allow you to move around and sleep more comfortably. However, you will need sufficient body heat to fill your space up. Here are some measurement factors you should understand when choosing a sleeping bag. 

·       Length

Choose the shortest length that fits your frame well and keeps your feet comfortable without being pressed when you wear your hood. Ensure your cold-weather sleeping bag has some room at the bottom area. You can use it (the extra room) as a storage space for your hiking clothes or shoes. 

·       Hip Measurement

Many male sleeping bags measure approximately 58 inches around the hip, while female ones can measure up to 60 inches. Try on different sleeping bag sizes to identify the best that meets your needs. 

·       Shoulder Girth 

Many sleeping bags come with a shoulder-length that varies between 60 and 64 inches. Cramped sleeping bags come with a 58-inch shoulder length. Female sleeping bags, on the other hand, come with a confined shoulder length that varies between 56 to 60 inches. Remember, 0ne inch makes a big difference in terms of snug level. The ideal way of determining the right size is to try various sleeping bag sizes. 

Getting the Best out of Your Sleeping Bag

After purchasing your sleeping bag, you want to do everything possible to get the best out of it. Avoid placing your sleeping bag on the ground. Always use a sleeping pad to protect your cold-weather sleeping bag, and keep it warm. You can warm your sleeping bag during the day by placing it under direct sun. You can also keep it close to the campfire in the evening.

If you are going camping during extreme winter conditions, use a hot water bottle. Doing so helps you get enough warmth and sleep comfortably. Take excellent care of your sleeping bag if you plan to use it for many years.

 Keep it uncompressed in a dry place to protect the filling from getting bundled up and crushing. Clean your sleeping bag and dry it thoroughly after every use, especially if it gets dirty or wet during your camping trip.
