SOURCING OF THE FEATHERS AND RDS CERTIFICATION

Our traceability system allows us to guarantee that the feathers are sourced in line with our commitment to using responsible materials. Our suppliers are committed to only using feathers (sourced in China) from ducks raised for their meat and plucked after slaughter.
As a result, we have received the RDS (Responsible Down Standard) certification issued by a third-party body.

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 nor 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.).
