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.

This is the closest bag to the one I got in 1990
Yes , I recommend this product
[This review was collected as part of a promotion.] This is the closest current Marmot bag to the one I bought in 1990. I use my bag at least three dozen times a year. One year, I used it more than 150 nights. I used it in Maine, Montana, and Mongolia. I thought it would be worn out by now, but there is no sign of that. It is 35 years old and warm no matter the outside temperature. WHAT A GREAT BAG!

Impressive for the Price
Yes , I recommend this product
Picked up for a trip to Mount Baker in the spring. Have since brought it out to sub 30 degree nights in NC and it has performed incredibly well with an R5 pad under it. Compresses down very small compared to other down bags I’ve used.

Comfortable and warm!
Yes , I recommend this product
[This review was collected as part of a promotion.] This is my first sleeping bag for backpacking and it's super comfortable and warm. The first time I used it, I slept so well that I thought I was at home.
