This article will pinpoint the key attributes to consider when buying a men's 20 degree sleeping bag. Starting at a length of 6 ft., these sleeping bags are designed to give men the right fit. However, they are less insulated than women's sleeping bags, so you'll need to choose one that is appropriately sized to maximize heat efficiency. They 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.
