But don't just take our word for it, check out some of the advantages and disadvantages of some of the main specs.

We've taken a look at waterproof 20 degree sleeping bags and wanted to share some information with you. 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 have a tight fitted hood design, which works well to seal in heat but doesn't allow for a lot of movement of the head and neck. They are closely fitted, reducing the amount of time that your body needs to work to heat up. 20 degree sleeping bags are more affordable than sub-zero degree bags, making them suitable if you're shopping on a budget. They protect against rain getting inside your bag, keeping out condensation so you'll be warm throughout the night. They are treated with a water repellent coating, allowing water droplets to bead and roll off the surface, so you'll stay completely dry inside.
