Many sleeping bags are rated for temperature by an independent testing protocol, the European Norm (EN) 13537. Each bag gets two ratings: a comfort rating and lower limit rating. The comfort rating is the lowest temperature at which the bag will keep the average woman (or "cold sleeper") comfortable, and the lower-limit rating is the lowest temperature at which the bag will keep an average man (or “warm sleeper”) comfortable. Everyone's body and sleep comfort is different, so EN Ratings are merely a guideline to help you compare products.
