There's loads to learn about sleeping bags, so we've reviewed large 20 degree sleeping bags to let you know all about both the pros and cons of these types of sleeping bags.

They are more affordable than sub-zero degree bags, so you can buy one without feeling worried about going outside of your budget. 20 degree sleeping bags are closely fitted, reducing the amount of space your body has to work to heat up. They have 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. Large sleeping bags are made from thicker materials than smaller and shorter sleeping bags, so they are super soft and cushioning. They are very spacious, giving extra room around the shoulders and torso for sleepers that need a bit of extra room.
