Technical Information

What level of warmth does this down jacket provide?
This down jacket, when worn as a 3rd layer, has a temperature rating of -10°C that was certified during a standardised test in a thermal chamber. The model is wearing a synthetic long-sleeved T-shirt and a light fleece underneath. It works with a simulated 5 km/h wind. We also tested this model under "static" conditions, its temperature rating is 0°C in this case.
The advantages of a duck down and feather filling
The fill power of down has 3 advantages for mountain sports: - 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
How to measure the fill power of a down and feather filling?
The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. It is expressed in CUIN. Consequently, the higher the fill power (i.e. the higher the CUIN number), the more space it occupies and the more air it traps thereby delivering more thermal insulation. This 85% down / 15% feather down jacket has a guaranteed fill power equal or above 660 CUIN (European standard).
* What is RDS certification?
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. We have been awarded the RDS (Responsible Down Standard) certificate by a third-party organisation.

How to maintain a jacket filled with down and feathers?
The down jacket can be worn throughout the winter and will certainly need to be washed. Follow our advice by clicking the link below: In brief: 1/ machine wash, 30°, with 2 or 3 tennis balls. Gentle spin cycle. 2/ tumble dry with 2 or 3 tennis balls, and repeat 2 or 3 times until it is completely dry.
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 down jacket as quickly, giving you time to find some shelter. But the down 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 restore the water-repellent properties?
Follow the guide: We recommend that you use the dip-coating care product It enables you to optimise the performance of your clothing throughout its lifespan.
