About Temperature Ratings

A sleeping bag does not generate heat, but "maintains" heat generated by body. If you are exhausted and cold and you slip in to your freezing and damp sleeping bag, you risk staying cold whatever the sleeping bag's features! These temperature ratings therefore depend on a person's resistance to the cold (build, fatigue, etc.), on their equipment (mattress that insulates from the ground, etc.), on their clothing (naked, underwear, etc.), and on weather conditions (damp, wind, etc.).
