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.

The mother of all chairs
Yes , I recommend this product
The chair was tested in real life camping and what a comfortable chair it is. Easy to set up. Light enough for us to handle in the high quality carry bag. It takes a bit of practice, but it can be set up securely in seconds by following the designed safety instructions. A real winner and we are totally pleased with our investment as this chair is built to last.

Great Bag
Yes , I recommend this product
I’m so happy I bought this bag, it’s been great! If you are someone who wants slightly more room to turn, I’d recommend the wide sizes. Folds down pretty small too.
