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.

I have had an opportunity to use this bag a few times, I like it a lot. Very comfortable and roomy! The pack size is a little bigger than my down bag but its not a issue for car camping. If pack size is not an issue I would definitely recommend this bag.

Forte is my go-to for Car/overland camping. I'm a side sleeper that likes a little extra wiggle room and this is perfect! Going to take advantage of the sale and upgrade my 20 forte and Disco 30 as well.

The Forte 20 has been fantastic so far. I went with the 20° because I’d always rather be too warm and vent the bag than end up cold when temps drop lower than expected. The Thermo Gills work great for dumping a little heat when needed. I also chose the regular wide version since I toss, turn, and sleep on my side constantly, especially while camping. The extra room makes a huge difference and the spoon shape actually lets you move naturally without feeling restricted. The hood, draft flap, comfort, packed size, and overall design are all excellent. Nemo really nailed the balance between comfort and packability. The updated storage bag is also a nice improvement over the older mesh sack. It takes up less space and sits nicely on a shelf. I also own the Disco (down), which is another awesome bag. The Forte packs down surprisingly small for a synthetic bag, but compared to my Disco down bag it still takes up close to twice the space in the compression sack. Just mentioning that for anyone comparing synthetic vs down options. I did catch the zipper a couple times, but honestly that feels like part of the sleeping bag experience no matter the brand. At least it’s way better than fighting with old sleeping bags from the ‘90s. Overall, this has quickly become one of my favorite pieces of camping gear.
