Imported.

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

2 weeks ago

[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!

[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.
