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.

[This review was collected as part of a promotion.] This sleeping bag is the nicest one I’ve ever seen and will use! It is extremely lightweight but still able to keep you toasty warm. It unzips two different ways so you can roll down the front flap or just unzip one side. It has snaps and bungee cords you can use to help lock in warmth and make sure you are keeping out the cold. The stuffing feels thin but that also helps it to compact and easily put back in the compression bag and storage carrier. This won’t add hardly any weight if you are backpacking into your camp. The size is great for one person but there is an option to zip two bags together to share. And I love that there are accessories available to buy separately for it like a pillow and an inflatable pad. Which if you are sleeping on rocky ground, you’ll probably want as this doesn’t have much “padding”. This sleeping bag is warm but breathable and for anyone who camps, this is expensive but definitely worth the quality to have.
