    Many sleeping bags are rated for temperature by an independent testing protocol. With both European Norm (EN) 13537 and International Organization for Standardization (ISO) 23537 testing, each bag gets a Comfort (or T-Comfort) rating and Lower (or T-Limit) rating. The Comfort/T-Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower/T-Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Ratings are based on a person wearing one long underwear layer and a hat, sleeping on a single 1 in. thick insulating pad. Many brands use the Comfort rating for women's bags and the Lower rating for men's and unisex bags. Everyone's body and sleep comfort differ, so EN and ISO ratings are simply a guideline to help you compare products.
