Our review process

We've taken a look at more than 800 sleeping bags, including many different extra large 20 degree sleeping bags. We used our artificial intelligence engine to rate each individual sleeping bag based on a number of data parameters. These features range from the temperature rating and the number of seasons to cleaning options and designs. The following guide will discuss extra large 20 degree sleeping bags in particular, of which we found 7. We hope that this article will help you choose the best one for you.

We've looked at extra large 20 degree sleeping bags and want to let you know about both the pros and cons. 20 degree sleeping bags should keep you comfortable down to 20°F, although do keep in mind that this doesn't account for variables such as layering, what you're wearing, and various other factors. They come with a tight fitted hood design, so they aren't the best choice if you want a lot of free movement around the neck and head. These sleeping bags are closely fitted, reducing the overall amount of space you have to heat up quicker and keeping you warmer. They are more affordable than sub-zero degree bags, so you can get these without feeling the stress of going above your budget. Extra large sleeping bags are made from thicker materials than smaller and shorter sleeping bags, so they are very comfy and cozy to sleep in. They are very spacious, designed for taller campers and those that prefer a bit of extra shoulder and leg room.

Rectangular Sleeping Bags

Trying to choose the most suitable rectangle sleeping bag for you? We can help you decide by giving you some important facts. These sleeping bags are roomy and spacious, so they are suitable for people who feel too claustrophobic by the tight mummy shape. They accommodate varying sleeping positions, allowing you to sleep in any position you need in order to get a good night's sleep.
