Finding the best sleeping bag for your travels can be a bit overwhelming with so many options to choose from â€“ synthetic, down, ultra-light, zero degree, warm weather, mummy or rectangular shape, womenâ€™s specific â€“ the list goes on and on.Â How can you possibly know what to choose?
Letâ€™s break it down.Â Really there are only 3 things you need to consider when choosing a bag â€“ temperature, insulation, and weight.
Every sleeping bag comes with a temperature rating which identifies the lowest temperature that the bag will keep the sleeper comfortable to.Â Say your sleeping bag is rated to 15 degrees.Â This means that the average sleeper should keep comfortable at temperatures down to 15 degrees.Â This doesnâ€™t necessarily mean you will sleep all warm and toasty at 15 degrees since many factors affect your warmth.
In general, estimate the lowest temperature you expect to camp in and then subtract 10 degrees to choose your temperature rating.Â If you are a cold sleeper at home you could benefit from an even warmer bag.Â Women tend to be colder sleepers than men so they usually prefer a lower temperature bag as well.
Sleeping bags are filled with either down or synthetic fibers and each has some pluses and minuses.
Down is by far the lightest, most compressible, and durable option but it comes with a heftier price tag than synthetic bags.Â Also, down bags lose their insulating ability when wet and it can take quite a bit of time for a down bag to dry out.
Synthetic bags perform well in wet and humid conditions; they will keep you plenty warm when wet and they dry quickly.Â Although synthetics are a bit heavier than down and donâ€™t compress as well, they will still keep you plenty warm.
I definitely prefer a down bag to a synthetic unless I am going to be spending a lot of time in wet and humid climates.
Depending on the type of camping you will be doing, weight may or may not factor into your sleeping bag decisions.Â If you will mostly be car camping or base camping weight really doesnâ€™t matter.Â If you wonâ€™t be lugging your sleeping bag for miles on your back you can pretty much choose any weight bag you like.
If you will be backpacking or trekking long distances with a sleeping bag, weight will definitely matter.Â Again down bags tend to be lighter and more compressible so most backpackers will want to shoot to for a bag in the 2-3 pound range and ultralighters will be happy to find a bag less than 2 pounds.

RECAP – How To Choose A Sleeping Bag in 3 Easy Steps:
(1) Estimate the lowest temperature you expect to camp in and then subtract 10 degrees to choose your temperature rating.Â Consider an even warmer bag if you are a cold sleeper or if you are female.
(2) Choose down if you want a lighter more compressible bag and if you plan on camping in drier conditions.Â Choose a synthetic bag if you will be camping in wet and humid conditions and if price is a concern.
