FORCLAZ by decathlon Trekking Sleeping Bag Mt500 5°c - Polyester

This sleeping bag was designed by our trekker-designers for bivouacking comfortably at night at temperatures greater than or equal to 5°C.

WHAT IS THE TEMPERATURE RATING?

We display the comfort temperatures on all our sleeping bags, tested by an independent laboratory (AITEX) in compliance with European standard ISO 23537-1:2022. The comfort temperature rating is the lower limit at which the user in relaxed posture is generally in thermal equilibrium and feels neither too cold nor too hot (for a standard woman in normal conditions of use). Choose your sleeping bag according to this criterion.

WHAT IS THE TEMPERATURE RATING (LOWER LIMIT AT WHICH YOU FEEL COMFORTABLE)?

The comfort limit temperature is the temperature limit at which a person curled up in the sleeping bag is in general thermal equilibrium, neither too cold nor too hot (determined for a man in normal conditions of use).We recommend using an insulation mattress to optimise your thermal comfort.
 

AN IMPORTANT CLARIFICATION CONCERNING THE ISO 23537-1 STANDARD

In the context of this standard, the measurement protocol of a sleeping bag’s thermal protection uses a mattress with thermal resistance equal to an R-value of 4.8.

This means that by using a less insulating mattress, the thermal performance of your sleeping bag will be lower.

We therefore recommend you use an insulating mattress to optimise your thermal comfort.
