Sleeping Bags — Temperature Rating

The Temperature Rating of Sleeping Bags

The temperature rating of a sleeping bag indicates the coldest temperature in which that sleeping bag will keep you warm.  While there are no required standards consistent among manufacturers, the EN 13537 is a European standard designed to standardize the temperature ratings on sleeping bags manufactured and/or sold in Europe. The temperature rating provided for a sleeping bag is only a suggested guideline to use as a starting point. There are many factors that will affect how warm you will be in that sleeping bag.

• What type of metabolism do you have? Are you a ‘hot’ sleeper or a ‘cold’ sleeper? Are you the one who sleeps with minimal covers or do you bundle under several quilts and blankets, and then you are cold when you wake up? If you are the latter then adjust the temperature down by 10 degrees.
• Will you be eating hearty and drinking a lot of water? If not adjust down.
• How does the bag fit? Do you have minimal air space or do you need space to move around? Can you sleep in the bag with the hood cinched around your face with just a small opening for breathing? If not, adjust down.
• What type of tent are you in? If you have a winter tent then less concern. Are you using a three season tent or a summer tent and it is cold out? Then adjust accordingly.
• On the other extreme, are you always hot while everyone else around you is chilled? Then adjust up.

Select a bag with a temperature rating of at least an extra 15 – 20 degrees lower than you expect ever needing. You will be able to use it in a range of temperatures and will also give you flexibility on how much or what type of padding you want underneath or how many layers of clothing you will wear.

Warm weather sleeping bags are great for family camping trips in the warmer climates. They do not need special insulation or a heavy shell. They can be very inexpensive, starting at $10.00 for a basic sleeping bag. When the kids have a slumber party they will be happy to sleep in their favorite sleeping bag as they share the floor space with their friends.

Three Season sleeping bags are a good investment if you camp often and want a bag that is versatile and functional. You can stay very warm when camping in climates where the evenings get cool. Select a temperature factor taking the above factors into consideration. A general guideline is to get one with a minimum rating of 15 to 20 degrees. If it is too warm you can always open up!

Winter sleeping bags are for campers that find themselves out in cold weather where the temperatures are below freezing. The design that is the warmest is the mummy shape, as you have less air space to keep warm and with a hood and draft collar it helps to lock in warmth. Both down and synthetic insulation will keep you warm. Don’t be stingy. If you are camping in the winter cold get a bag with a rating of -40. Don’t be surprised by the cold winds blowing! Any winter bag must also have zipper draft tubes, shoulder collars, and a hood the fits close around the head to make sure you stay warm.
