What you must know 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 into 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, windy, etc.).

A rating for comparing products’ environmental impact

Product’s environmental impacts are calculated throughout its lifecycle and with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, pants, backpacks, etc.).
