Sleeping Bag Temperature Ratings Explained: How to Choose the Right One

You’ll need a sleeping bag to keep you warm and cozy while camping, but how do you know which one is best for the conditions where you’re going to be camping? Temperature ratings for sleeping bags can seem confusing at first glance. There are many different temperature ratings for sleeping bags. Which one should you choose? The answer isn’t as straightforward as it might seem. Let’s take a look at the different types of temperature ratings and how they apply to sleeping bags so that you can choose the right one for your next trip into the great outdoors.

What is a Sleeping Bag Temperature Rating?

A temperature rating tells you the lowest temperature that a sleeping bag is designed to keep you warm in. This rating is usually given on a scale of low, medium, and high. Each manufacturer has different temperature ratings for their sleeping bags. This is why it is an important factor when choosing a sleeping bag. A sleeping bag’s temperature rating is based on its insulation and shell material. This means sleeping bags with a higher rating are best for colder temperatures than sleeping bags with a lower rating. If you choose a sleeping bag with a low rating, you may not be warm enough at the lower temperatures. And if you choose a sleeping bag with a high rating, you may be too hot at the higher temperatures. Check out Oz Backcountry for a sale on down sleeping bags.

Which Type of Temperature Rating Should I Look For?

If you aren’t sure what type of temperature rating you should be looking for when choosing a sleeping bag, you’re not alone. It can be confusing to understand everything that is involved with sleeping bag temperature ratings. There are many different types of temperature ratings for sleeping bags. 

The Comfort Ratings

These temperature ratings indicate the lowest temperature that a person wearing the bag will be comfortable in. They are not an indication of how warm the bag will keep you. They are based on the comfort of the person wearing the bag. Two people may not be comfortable in the same sleeping bag in the same conditions. This is why it is important to look for the rated and extreme temperature ratings as well when choosing a sleeping bag. If you are camping in mild temperatures, you can get away with choosing a sleeping bag with a low comfort rating. However, if you are camping in colder temperatures, you will want to choose a sleeping bag with a higher comfort rating.

The Rated Ratings

These temperature ratings indicate the lowest temperature that a person wearing the bag will be warm in. A sleeping bag’s rated temperature rating is a combination of both the insulation of the bag and the person wearing it. Two people may not be warm in the same sleeping bag in the same conditions. This is why it is important to look for the rated and extreme temperature ratings as well when choosing a sleeping bag. If you are camping in colder temperatures, you will want to choose a sleeping bag with a higher rated temperature rating. It is important to note that sleeping bag temperature ratings are not regulated. This means that different manufacturers will have their own way of testing their sleeping bags’ temperature ratings. For this reason, the rating that one manufacturer gives their sleeping bag may not be the same as the rating that another manufacturer gives their sleeping bag for the same temperature.

The Extreme Ratings

These temperature ratings indicate the lowest temperature that a person wearing the bag will be safe in. They are a combination of both the insulation of the bag and the person wearing it. Two people may not be safe in the same sleeping bag in the same conditions. This is why it is important to look for the rated and extreme temperature ratings as well when choosing a sleeping bag. If you are camping in very cold temperatures, you will want to choose a sleeping bag with a higher extreme temperature rating. It is important to note that sleeping bag temperature ratings are not regulated by the government. This means that different manufacturers will have their own way of testing their sleeping bags’ temperature ratings. For this reason, the rating that one manufacturer gives their sleeping bag may not be the same as the rating that another manufacturer gives their sleeping bag for the same temperature.

Synthetic Bags vs. Down Bags and Their Ratings

Synthetic sleeping bags typically have higher rated temperature ratings and lower extreme temperature ratings than down bags. This is because synthetic fibre has a higher “fill power” than down. Fill power indicates how much insulation a bag has. Synthetic sleeping bags typically have a higher fill power than down bags. This means synthetic bags will be better at keeping you warm in colder temperatures than down bags. Down sleeping bags typically have lower rated temperature ratings and higher extreme temperature ratings than synthetic sleeping bags. This is because down bags have a lower fill power than synthetic bags. This means down sleeping bags will be better at keeping you warm in colder temperatures than synthetic sleeping bags.

Conclusion

When choosing a sleeping bag, keep in mind that temperature ratings are not exact. They are based on the conditions of the testing environment and the person wearing the sleeping bag. That being said, temperature ratings are a good indicator of how well a sleeping bag will perform in certain conditions. They can help you choose the best sleeping bag for your needs based on what type of trip you are planning.
