What does RDS* certification mean?

Ethical down certified by RDS (Responsible Down Standard).
Thanks to our traceability system, we can guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers are committed to using only feathers that come from ducks that are bred for their meat and which are plucked after slaughtering.


Fill Power of down/feather filling

For this down jacket with its 85% down/15% feather filling, the fill power is guaranteed to be 660 CUIN or more (European standard).

The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. So, down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation.

What are the benefits of a duck down and feather filling?

The durability and fill power properties of down give this jacket 3 qualities for hiking:
- Thermal insulation thanks to the air trapped in the down and feathers
- Ultra-low weight: down is lighter than synthetic wadding while offering the same degree of warmth. This saves even more weight in your backpack
- Ultra-compressible

In case of rain

The material of the quilted jacket is water-repellent. This means that drops of water roll off the fabric, preventing them from soaking into the padded jacket as quickly, giving you time to find some shelter. But the padded jacket is not waterproof. We therefore recommend wearing a waterproof jacket over the down jacket in the event of prolonged exposure to rain.

How to wash your feather down jacket

Here are a few tips: close all the zips on your down jacket and put it in the washing machine (synthetic cycle at 30°C).
In order to preserve the fill power and warmth, you can even put 2 tennis balls in the machine
Be careful to set a gentle spin cycle: a fast spin cycle may create balls of feathers that are difficult to break up.
