Feather origin

Thanks to our traceability system, we can guarantee the origin of the feathers, which are sourced in accordance with our responsible material commitments. Our suppliers are committed to using only feathers that come from ducks that are bred for their meat and are plucked after slaughtering.

The advantages of a duck down and feather filling

The down's long-lasting fill power gives it 3 important qualities for hiking: - Thermal insulation thanks to the air trapped in the down and feathers - Ultra-lightweight: with equal warmth, feather is lighter than synthetic padding. This saves even more weight in your backpack - Ultra-compressible

Fill power of the down/feather filling

For this down jacket with its 85/15 filling, the fill power is guaranteed to be 800 CUIN (European standard). The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" a certain volume of air. Down with higher fill power (a higher CUIN number) takes up more space, trapping more air and providing greater thermal insulation.

Care instructions for jackets filled with down and feathers

The down jacket can be worn throughout the winter and will certainly need to be washed. Follow the instructions by clicking the link below: How to wash and dry your down jacket

In the event of rain

The material of this padded jacket is water-repellent. It makes drops of water run off the surface, which delays the time it takes for water to get inside the down jacket, giving you time to get out of the rain. However, we advise you to wear a waterproof jacket over the down jacket in case of prolonged exposure to rain.
