Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

Best cold weather backpacking bag
1 month ago
Have used this on the AT and in New Mexico, high plains. Very light for the superior insulation it provides. I used a water proof compression bag to stowing in the backpack; compressors very small. Slept like a baby below 20 degrees F. The material feels very nice to me personally. A bag liner helps below 10 degrees. It actually did perform well slightly wet. I cannot sing this bags praises more. Simply excellent!
