Buyer's Guide to Rectangular Sleeping Bags

If you're searching for the best rectangular sleeping bag but don't know where to start, here are some key factors to keep in mind, that will help you make the right decision for your needs.


It's always a good idea to consider your intended activities, because it will help you to choose sleeping bags that you'll get excellent use out of, whether you prefer a rectangular or mummy-shaped bag.

For example, if you're going to be backpacking for a longer period of time, try to select a bag that's fairly lightweight, and can be easily compressed into a stuff sack for easy portability. It might also be a good idea to select a bag with a built-in pillow or gear pockets, which will reduce the number of extra items you'll need to carry with you.

If you're a casual or car camper, you can consider sleeping bags that are thick and comfortable, as portability won't be an issue. You might also want to consider models that don't come with a plethora of extra features, as car camping often affords you much more space to pack!


Insulation is one of the most important factors in this buying guide. Without the correct fill type or warmth ratings, your sleeping bag won't be able to do its job properly. 

All sleeping bags have a warmth rating - this is the lowest temperature at which your sleeping bag will be able to keep you warm when used with a sleeping pad. Most 3-season bags will have a rating of around 30°F , meaning they'll be able to keep a person warm on most evenings throughout the year, but not in conditions that are below freezing. 

If you're going cold weather camping, it's really important to ensure your sleeping bag's temperature rating is lower than the expected temperature at your campsite, so that you don't get caught out.

Don't confuse your sleeping bag's warmth rating with it's comfort rating - this indicates the lowest temperature at which your bag can keep you comfortable, not the lowest temperature it can keep you safe.

The type of insulation you should choose will come down to personal preference. Down tends to have a higher fill power, meaning it can keep you warmer with less material. However, synthetic fill can often resist water and keep you warm whilst wet, so it's worth considering all options.


No matter how many extra features your bag has, if it's not comfortable, you simply won't enjoy using it. Many sleeping bags include excellent provisions to help boost your comfort, and make your camping trip much more luxurious.

Try to look for bags with sewn in panels that prevent the filling from forming uncomfortable clumps - this can actually improve the longevity of your bag, too. Bags with draft tubes or neck cuffs will help protect you against the cold air, and will allow you to stay warmer for longer. You should also check the lining fabric of your bag, to make sure it won't irritate your skin.

Ultimately, the best rectangular sleeping bag for you will be the one that keeps you warm and cosy all night, so it's definitely worth searching for bags with added comfort features.

Extra Features

Sleeping bags with extra capabilities can certainly be useful on the trails, especially if you're looking to pack light! Here are some common extras to look for:

  • Built-in Pillows: When you're hiking for long periods of time, saving space in your pack is essential! Choosing sleeping bags with built-in pillows means you'll have one less item to carry, and can help keep you comfortable, too.
  • Compression Features: Whether your rectangular sleeping bag comes with an included stuff sack, packing cords, or a carry bag, having some assistance with packing your gear can make breaking camp much more efficient.
  • A Hood: Many people enjoy the shape of mummy bags, but wish they had more space to move. Rectangular sleeping bags with hoods are an excellent solution to this issue, as they help keep you warm, but won't restrict you as you sleep.
  • Storage Pockets: If you're concerned about protecting any valuables, look for sleeping bags with storage pockets. They'll help you keep track of what's important, and can make packing easier, too.


The best rectangular sleeping bags for your needs aren't always the most expensive!

If you're a keen camper who is on the trails every weekend, it may be best to invest in a premium rectangular sleeping bag - but make sure it's well insulated and comfortable, so that you get more value for your money.

However, if you're a casual or infrequent camper, you can easily find rectangular sleeping bags under $50, that will do an excellent job at keeping you warm and cosy in all conditions. It's always best to do your research and shop around, in order to make sure that you've chosen the best sleeping bag for you.
