It only means that you can survive at such a low temperature, but whether you can fall asleep depends on each person's physique. Usually, men can withstand extreme temperatures; women can withstand limit temperatures, and each person's physique is different in temperature. We must be not recommended and opposed using the sleeping bag at below this low temperature.Comfortable temperature: Refers to the ideal temperature for comfortable use of the sleeping bag. At this temperature, people can fall asleep very comfortably, without being unable to sleep because of the cold.It should be noted that the comfortable temperature is only a relative concept. Sleeping bag products temperature range is based on laboratory tests and field experience by brander research institutes to calibrate their products with comfortable temperatures. This temperature is only a reference, each person's body is different, and the environment is generally different(like rainy, snowy, windy may more cold) generally everyone can withstand different temperatures. For every sleeping bag, we suggest every user can use the sleeping bag at the suggest comfortable temperature, at least female and the kid must use at a comfortable temperature that can ensure your good and warm sleep night.Q&ADose it has smell?No smells.
