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.

Needed an economical sleeping bag that i didn't mind getting beat up for a survival class. It kept me warm in my makeshift shelter, in 5 degrees, while the wind was ripping at 7'000 feet.

Great Sleeping Bag

Purchased this about 1 month ago and have slept in it a few times already. Once, in a hammock and it was plenty warm when it was frosty in the morning. Then again, when the temperature was warmer, it got very hot in the back but just unzipped a bit to cool off. The bag got rained on during a thunderstorm and the wetness just pooled up on the outside. Some moisture did wick into the insulation, and even though it felt a bit damp inside, I stayed warm. It can be a bit of a snug fit if you are a full size person and my wife did not like it but it's not meant for women.
