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
[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
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!
[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.
Down sleeping bags.
I have purchased five sleeping bags over the years I personally have the helium plus 15 sleeping bag What a great roomy bag it is.
[This review was collected as part of a promotion.] I have gone on several backpacking trips, and the light weight and compactness of the bag was a pleasure.
Great bag
[This review was collected as part of a promotion.] Great bag, warm and comfortable. Glad I got it, best one I have ever had.
