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.

Good Basic mummy bag
3 weeks ago
This bag holds up to its temp rating. Given that it's synthetic, its a little bulky in the stuff sack but it fits in my Granite gear 60 L pack easily. The hood is a little annoying as its fairly tight even at the lowest level of tightness. Very comfortable bag and super spacious. I'm only 5'10 and the large fits my body length almost perfectly. I have probably 3-4 inches of excess bag length-wise. No pockets inside or any crazy features. Just a good basic mummy bag IMO.
