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.

Excellent warmth, on the larger side

This sleeping bag is solid and warm, and it'd be comfortable in the upper 20s. The only problem for me was that the length of the bag was a bit too big for what it says "Regular". I'm 5 10, and when I use the bag, it has well 1 foot extra space, which in lower 20F might become a problem. (of course, you can stuff down your bag with your clothes and a bottle of hot water).

[This review was collected as part of a promotion.] I spend most my summer in a sleeping bag in Grand Canyon. I've been looking for a bag that is synthetic, offers more leg space than a mummy bag but with a hood so I don't loose my pillow in the river when I sleep on my raft. Not too bulky so it fits nicely in my dry bag. Zips all the way open so on warmer nights I can just sleep on top of it. Perfect fit for this traveling river girl.

The Perfect Summer Bag!
5 days ago
[This review was collected as part of a promotion.] I'm segment backpacking the Colorado Trail and needed a lighter weight bag for the warmer trips out, and this bag is perfect all the way around, literally! I'm 5'2", 115# and the short length is wonderful in terms of roominess, length, and packability. The included compression sack really gets this bag cinched down. The zipper is easy to use, it doesn't catch and it's a great option to open the foot of the bag or open it all the way into a quilt! This sleeping bag really is the best!!

[This review was collected as part of a promotion.] Seems durable which is what I wanted in contrast to my down bag. I appreciate the shorter length!
