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.

I would buy this bag and recommend to others.
I am 6' 275 and the bag is more than big enough. I used it in a high mountain elk hunt this year the first of November. Low temperature was 13 degrees Fahrenheit. Was very comfortable with one of the expansions open. On warmer nights I opened both expansions and unzipped the lower part of the bag and was comfortable. The only thing that I would mark the bag down would also make it not as warm, but would put fuel side entry. They way the tent was set up the exit for the bag was against the tent to keep my head uphill. Zippers worked great, expansion worked amazing, light weight enough for backcountry trips, overall a great bag!! I am going to be purchasing this bag in a higher temp for summer trips.

An excellent product
This product is excellent. I used it on a river trip this spring and really appreciated the extra leg/foot room afforded by the double zip option. I also really like the pillow holder. You can stuff it will a puffy coat if traveling light or a small down pillow.
