Most sleeping bags are rated to keep the average person warm when the temperature is between 15 and 50 degrees, so you’ll have no trouble locating sleeping bags with a 20 degree temperature rating. Look for sleeping bags with a double layer construction and off-set quilting. This type of design eliminates pockets where cold air gets through. You’ll also want to make sure that the outer shell is water-resistant and that it has a zipper tube that prevents cold air from entering through the zipper.
Most 20 Degree bags will have hoods with a drawstring that pulls the hood tightly around your face. Be aware that the 20 Degree rating is merely a guide that varies between campers.

Winter Sleeping Bag vs. Sleeping System for Camping
Going camping or backpacking in the winter requires advance planning. Taking a sleeping bag that is properly rated for the temperatures makes all the difference between having a rewarding and successful trip and a frustrating, unsuccessful trip.
Sleeping bags are tested in varying temperatures to determine the lowest temperature that will keep the average person comfortable. People’s body temperatures and individual metabolisms vary widely, so the ratings are intended to be used only as a guide. Each person has to determine their own comfort level.
As a guide, summer season sleeping bags are rated for temperatures 35 degrees and higher. Three-season bags are rated for 10-35 degrees. Anything lower than 10 degrees is considered a winter-rated bag.
While temperature ratings are important, they should be considered one part of the overall sleep system for camping. The sleeping bag doesn’t do so well on its own, so it takes a little help from other camping gear. A sleeping pad or air mattress separates the bag from the cold air on the ground. A sleeping bag liner helps keep warm air inside the bag. Don’t forget about the added benefits of thermal underwear, coats, hats, and gloves to ensure a warm sleep during your winter camping trip.
