Many sleeping bags are rated for temperature by an independent testing protocol, the European Norm (EN) 13537. Each bag gets two ratings: a Comfort rating and Lower Limit rating. The Comfort rating is the lowest temperature at which the bag will keep the average woman (or "cold sleeper") comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep an average man (or "warm sleeper") comfortable. Everyone's body and sleep comfort is different, so EN Ratings are merely a guideline to help you compare products.

Rated 5 out of 5 by from A lot of product for the price! I bought this bag after a very cold and windy backpacking trip at Big Bend Nat'l Park. I used it for a 4 day trip to Guadalupe Mtns Nat'l Park and local overnighter. The first trip the temps dipped into the high 30's and this bag handled it well. I don't find the bag anymore claustrophobic than any other mummy I've used. It is lightweight and warm. Plus, i don't have to worry about it getting wet. I've already washed it once, (big agnes' website has excellent instuctions) and it's still as good as when i bought it.

Rated 3 out of 5 by from Time will tell Bought this new bag a few weeks ago. I like the synthetic fill which mimics down. Very lightweight and no worries about a little water like down. However, this bag is not roomy even though it's a long. I feel a bit clostrophobic in it. Zipper sticks too. It's a mixed bag.

Rated 5 out of 5 by from Solid sleeping bag Just took this bag out camping in Colorado and it dipped down to the 30s and it kept me plenty warm. It packed down really small and fit at the bottom on my day pack. Couldn't be happier with this purchase.

I see that the stuff sack size 8.5" x 18", but what is the compressed stuff sack size in inches with the bag stuffed in?

Asked by: Shaddy78
​The 8.5 x 18 inch size listed in the specs is for the compression sack. That is the size of the sleeping bag when compressed in the compression sack.
