Only the most rugged outdoorsmen and adventurists are inclined to try winter camping. For those who enjoy it, part of the challenge is planning and packing gear that keeps them warm. A 0 Degree mummy sleeping bag, a sleeping pad, a sleeping liner, and thermal underwear are staples for camping in cold temperatures. Mummy-style or barrel-style sleeping bags hug closely to the body to preserve body heat.
Temperatures can drop during the night, so select a bag that withstands colder temperatures than you expect. You can always vent the bottom of the sleeping bag if you get too warm.

0 Degree Sleeping Bag vs. 20 Degree Sleeping Bag
Temperature ratings are intended to be used as a basic guide, rather than a hard-and-fast rule. Since everyone’s body regulates temperature differently and metabolisms vary greatly, it’s almost impossible to develop an exact rating for sleeping bags that protect in sub-freezing temperatures.
Most camping sleeping bags will keep you warm between 15 and 50 degrees. Sleeping bags that are rated for 10 degrees and lower are considered winter sleeping bags. When a bag is rated as a 0-degree bag, it simply means that the bag is intended to keep an average body warm at that temperature. The same rating also assumes that the sleeping bag inhabitant is wearing a layer of thermal underwear and that they placed a quality sleeping mat beneath the sleeping bag.
It’s fair to say that you can use a 0 degree sleeping bag in 20 degree weather, but it wouldn’t be prudent to take a 20-degree sleeping bag when you expect temperatures around the zero mark. If you need warmer sleeping bags, check this page for more options.
