Temperature rating

On all our sleeping bags, we display the temperature ratings determined by testing in an independent lab (AITEX) based on European Standard EN 13537 (2016). The "comfort temperature rating" is the lower limit when a user in the sleeping position is generally in thermal equilibrium and is neither hot or cold (based on a "standard" woman in normal conditions of use). Choose your sleeping bag based on this feature.

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.). Decathlon chose to apply this voluntary environmental labeling system. To get more information:


Padding : 90.0% Grey duck down, Padding : 10.0% Grey duck feather Main fabric : 100.0% Polyamide Carry bag : 100.0% Polyamide

Storage Instructions

Store your sleeping bag in its storage cover in a dry place because there is the risk of the down deteriorating if it is compressed for too long in its compression sack
