When camping or hiking, it’s essential that you have the proper gear to stay warm and toasty at night, so you can sleep soundly. A sleeping bag is indispensable, but are all sleeping bags created equal? But what does that number mean, is it the only number you need to pay attention to, and how does it actually work beneath the rating labels’ numerical hype? At ThermaRest, we’re here to break down the science of sleeping bag temperature ratings to help you make sense of what to look for in a sleeping bag to get better camping night’s sleep.
It's All About Temperature Accurate temperature ratings on sleeping bags are a must!
Temperature ratings on Sleeping bag are very important because they help to give you an idea of what to expect from the sleeping bag and how well the sleeping bag will keep you warm in different type of temperature conditions. The temperature rating is typically a range, like 20 to 30 degrees Fahrenheit. That means the sleeping bag should keep you warm in temperatures ranging from 20 to 30 degrees Fahrenheit. If you pull in a sleeping bag that is not rated for the temperature you find yourself camping in, you could wake up and be very uncomfortable all night long.
Myth 2: What insulation materials can tell you about a sleeping bag's warmth:
In a sleeping bag, it’s the insulation materials that make the sleeping bag warm. There are two main types of fill insulation that sleeping bags come with: down, and synthetic. Down insulation, which is harvested from ducks or geese, does a really good job of trapping heat (after all, these animals must stay warm outside). Synthetic insulation: Made with some type of man-made material, synthetic insulation is also an excellent insulator. I always see an amusing amount of confusion around what section the sleeping bag insulation goes into to make it stuff in there— I hope that becomes clearer in a second! What Type of Sleeping Insulation Should I Use?
How your metabolism and body heat interact with sleeping bag temperatures:
Your body metabolism and body heat also factor in to what you feel as warm in a sleeping bag. Some people simply produce more body heat than others, so they might feel warmer when they sleep in a bag with a lesser temperature rating. On the other hand, if you get chilled easily, you may require a sleeping bag and a Camping tent with a higher temperature rating to make sure you stay comfortable. "When selecting a sleeping bag it is important to consider what temperature your own body needs to remain warm.

The weather can also play a role in how effectively a sleeping bag keeps you warm. When it is windy or rainy outside, you’re likely to lose heat more quickly and feel colder in your sleeping bag. It’s also wise to pack extra layers of clothing as well as a thermal sleeping pad that you can use in conjunction with your sleeping bag if it’s colder than anticipated. Make sure to plan ahead by checking the weather forecast before you venture off on your outdoor adventure.
Tips for choosing the right temperature rating on a sleeping bag for your outdoor adventures:
When selecting your sleeping bag's temperature rating, take into account the coldest temperature you will be sleeping in. A sleeping bag with a lower temperature rating can keep you warm when camping in cooler temperatures. But if you are going camping in the milder weather then you would feel comfortable with a sleeping bag that has higher temperature rating. Another good idea is to experiment with different sleeping bags before you head out on your camping trip and try some out to decide what feels the best to you.
In summary, Sleeping bag temperature ratings should play a big role in your decision making as you prep your outdoor expeditions. Understanding the science of sleeping bag temperature ratings, combined with your own knowledge of how you sleep, insulation factors (down vs. synthetic), whether you run hot or cold in normal life, metabolism, and weather, will help you select the best sleeping bag to keep you toasty at night. Remember to plan for a changing climate and to choose the appropriate sleeping bag temperature rating that is best for your adventure or camping gear needs. Happy camping!
