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.

Nice and toasty
Grabbed this bag before a camping trip out to the Colorado Flat Tops where the lows were expected to be in the low 20s. Definitely not near 0 degrees, and I was in a roof tent with an Exped DeepSleep Duo mat wearing a smartwool base layer. With the zips pulled down a little bit it gave me a bit of ventilation, but kept me plenty warm with plenty of room to move around, a huge plus for being a side sleeper.
Mediocre build quality, bulky for down, but warm.
This is pretty bulky about the same size as my old synthetic one. Build quality is mediocre at best. Loose threads on every stitch. Dos not zip all the way down so you need to wiggle yourself out of it. But its warm. I guess you get what you pay for.
Go Long!
I’m 5’11” and 210lbs, so usually the regular length bag works. This is a pretty snug fit in both length and circumference at the shoulders, so I’d recommend the long size. I do like that the foot box has an expansion zipper.
