We've taken a look at 20 degree double sleeping bags and wanted to share some information with you. These sleeping bags should keep you comfortable down to 20°F, but remember that this doesn't account for variables such as layering, what you're wearing, and various other factors. They are more affordable than sub-zero degree bags, so you can get these without feeling the stress of going over your budget. 20 degree sleeping bags are tight fitting, reducing the amount of space your body needs to work to heat up. They have a tight fitted hood design, which works well to seal in heat but doesn't allow for a lot of free movement of the head and neck. Double sleeping bags also feature a design that is great for two people, making them great for winter getaways. They are suitable for car camping, so you'll sleep better when you're not constricted and weight isn't an issue. However, they take up a lot of space, making them less ideal for backpacking pursuits.
