Temperature rating
We display on all our sleeping bags, the temperature ratings tested 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 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.).
A rating for comparing products environmental impact
Product's environmental impacts are calculated throughout its life cycle 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, trousers, backpacks, etc.). Decathlon chose to apply this voluntary environmental labelling scheme. To get more information:

    Entspricht nicht der Beschreibung

    Ich habe den Schlafsack wegen seiner Komforttemperatur von -9° bestellt.
    Tatsächlich ist auf dem Schlafsack nur eine Komforttemperatur von -6° vermerkt.
    Ich bin sehr enttäuschend, dass bei Decathlon solche Fehler in den Produktbeschreibungen auftauchen. Was soll ich dann noch glauben?

    Brand response :


    vielen Dank, dass du dir die Zeit genommen hast, den Schlafsack zu bewerten. Wir bedauern sehr, dass du unzufrieden mit der Beschreibung von diesem Produkt bist. Die Online Informationen und die Bedruckung auf dem Produkt waren tatsächlich widersprüchlich und die Marke hat es jetzt korrigiert, wie du es auf diesem Foto sehen kannst.

    Das darf natürlich nicht passieren. Ich entschuldige mich für die Unannehmlichkeiten und wünsche dir einen schönen Tag.

    Viel Spaß beim Sport!

    Mit sportlichen Grüßen

    Excelente calidad

    Gran saco de excente calidad. Muy buena capacidad de inflado y calienta muchísimo. Las medidas de el saco en compresión están mal, coríjanlas urgentemente ya que yo lo compré pensando que tenía una dimensiones muy reducidas y no es así. Por el problema de peso y medidas me quedaré con el makalu I, de prestaciones similares pero mucho más pequeño y ligero. En cualquier caso, el producto es de mucha calidad y si cumple con lo especificado.

    No está bien diseñado, el frío se cuela por la cremallera.
