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.

Zippers keep getting stuck
1 year ago
Lightweight and compact however the ventilating zippers repeatedly snagged on the fabric and would jam.

Originally got this bag last year in September with the intent of using it during the fair weather seasons, however have used it maybe three time and all three times it was not great. Used it in September and October last year and felt like I was sweating to death even though I had the vents open on the bag. Left it alone for a bit but tried again this weekend with temps in the 40s overnight, and the bag once again failed me. I was reasonably frigid overnight, with the vents now closed. Not sure how to feel about this since I was referred the bag by an rei employee for my need of a mid temp bag, but this thing doesn't seem to cover any of the camping I've done with it even a year later.

Not a 35 degree bag
1 year ago
I had bought the womens model, but it was too narrow in the shoulders, so I bought the men's version of the same bag without looking at it. I spend a week camping at 35 degrees. I used a liner and had to wear two layers of underwear and put my down jacket and pile jacket over the top. When I looked at the bag in the sun, there were huge swaths with no fill at all. Boo!

Comfortable and Roomy Sleeping Bag
8 months ago
This bag is a great sleeping bag for those who prioritize comfort on camping trips. The spoon-shaped design is a game-changer, offering extra room to move around—perfect for side sleepers like me. The material feels soft and cozy, and the integrated blanket fold is a nice touch for added warmth on colder nights. I’ve used it in temperatures close to its lower limit on the app trail, and it kept me warm, though I’d recommend adding a liner for extra insulation in truly cold weather. The bag is lightweight and packs down well, which makes it easy to carry on backpacking trips. My only gripe is the zipper, which can be a little finicky at times—it occasionally snags on the fabric. But overall, the Nemo Forte strikes a great balance between comfort, weight, and packability. A solid choice for three-season adventures!

Great comfort
5 months ago
I have had this for more than a year and used on over a dozen camping trips with the Scouts. It has not disappointed in the level of comfort and warmth. The shape is what drew me to this bag because I fidget when I sleep and I roll around. This bag is perfect for that because there’s room for my knees to shift and curl as well as my shoulders. My only area for improvement is the zipper. It tends to grab the material inside the bag I have not broken or torn it but it can be frustrating to have to pull that material out of the zipper.

I bought this bag about four years ago. Love the extra room. I sleep warm and had this bag to 39 degrees several times. Lowest was 22 degrees with no tent, it was fun but I didn’t die. I move around a lot at night and the shape is perfect.

The zipper vents didn't work
8 months ago
This bag checked all my boxes, and I wanted to like it. For my trial run, I just setup the sleeping bag on the living room floor. Immediately, I couldn’t get the vent zippers down. I kept at it and eventually got them down. Getting them back up, I have finally given up and will be taking the bag back tonight. I don’t need a bag that is this difficult, especially if I'm in the dark and when I'm cold. That is a recipe for a broken zipper.

We bought a few weeks ago and got the opportunity to take it out. It was perfect temp for him-who-overheats! He hasn’t camped since he was a kid and was finding it hard to get comfy. The extra knee space of the spoon bag and that perfect temp made our trip more enjoyable because he could finally sleep well! This combined with an insulated Astro pad was the perfect ticket! Thanks for making excellent products!
