Sleeping bag rating is really a large part of picking the correct sleeping bag for you. When looking for a sleeping bag you want something that’s going to be good for the weather you are likely to be in. if you are going to require a sleeping bag for temperatures as low as -60 degrees Fahrenheit, then you’re likely to want a sleeping bag that complies with your specifications.
At this time, the coldest sleeping bag you will discover is -60 degrees and they’re made by Wiggy. A Wiggy bag can have a rating of -80 if you get the over bag, for those of you serious mountain climbers this may be something to check out. For those of you that dwell in a warm climate region and it hardly ever get colder than 30 degrees you are likely to want a sleeping bag with a rating of 25 degrees, just to be on the comfortable side. When choosing a sleeping bag it is most effective to recognize how you sleep.
Some questions you might wish to ask yourself would be are you a cold or warm sleeper, do you put the heat in your house to 68 or 90 in the winter. This all plays big roles in the bag you will want to choose. Should you set your heat to 90 then you may wish to adjust the rating standards for a bag that is 10 degrees colder than the climate will get. Should you set your home to 68 then it may be a good choice having a sleeping bag that fits the specifications of coldest weather exactly.
I personally use a sleeping bag rated at 0 degrees Fahrenheit simply because I can always unzip it and let the breeze in or use it as a quilt. I go camping all four seasons and in those colder conditions I use over one bag that puts my rating to -25. Whatever your needs are for sleeping it’s good to check those sleeeping bag ratings out and select the right bag for what you are going to be using it for.
