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

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

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

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

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.

Use it for backpacking

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.

Had a flaw

When I got this item home I discovered that one of the zippers of the "thermo-gill" feature had a wicked bad fabric snag in the zipper and there was no way to free it without ripping a hole in the fabric inside the gill. Well, rather than bring it back I fixed it using some Tenacious Tape patches. Bringing it back would have cost me time and gasoline. So if you are looking at this item in the store inspect it thoroughly. This is the second time I've had a defect in a Nemo thing.

Forte - great features for a great price

I bought the Forte (men’s 35 degree regular) for a four day trip on the Suwannee River in Florida. I already own Nemo Disco and Riff down sleeping bags and love the spoon shape. I chose the Forte because it has synthetic insulation and would perform better than down should it have gotten wet. Luckily it didn’t. The nights ranged from the low 50’s to the upper 30’s and with the Thermo Gills I was able to regulate the temperature in the bag for a comfortable night’s sleep each night. Being a kayaking trip the weigh and packed size was not a big concern but this bag packs small and is light weight. The only drawback is the hood doesn’t seem to be as roomy as the hood on the Disco and Riff. I paired this bag with the Nemo Tensor regular-wide sleeping pad and the Nemo Fillo pillow for an awesome sleep system.
