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.

Comfortable and super warm. I would recommend this to anyone doing spring and fall camping in high mountains. I used this bag on a night that got down to about 15-20 degrees F and was warm and toasty with no layers on. It is a MUMMY bag so if you like a lot of room when you sleep, this probably isn't for you. Good for car camping or maybe a short hike (not light or compact) but it does what it is supposed to.

Definitely warm!
Used it on a trip to the badlands in mid-October. The coldest it got was around 38 degrees so it didn't quite test the limits of what is advertised but it had no problem holding up to the cold.

Warm Sleeping Bag
Yes , I recommend this product
This was a great sleeping bag for a winter camping trip. I didn’t need a liner because I was kept so warm with my sleeping bag on its own in my tent.
