Technical Information

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 which are plucked after slaughtering.
Fill Power of the down/feather filling
For this down jacket filled with 85% down/15% feathers, the fill power is guaranteed to be greater than or equal to 660 CUIN. The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. Down with higher fill power (a higher CUIN number) takes up more space, trapping more air and providing greater thermal insulation.
Weight of the filling
XS: 162 g S: 170 g M: 178 g L: 188 g XL: 198 g: 208 g XXXL: 220 g
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 wadding. This saves even more weight in your backpack - Ultra-compressible
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:
In the event of rain
The material of this padded jacket is water-repellent. It makes drops of water run off the fabric so it takes longer for water to get inside the jacket, giving you time to find shelter. But the padded jacket is not waterproof. We therefore recommend wearing a waterproof jacket over the down jacket in case of prolonged exposure to rain.
A score for comparing products' environmental impact
The product's environmental impact is calculated over its entire life cycle using different indicators. An overall score from A to E is given to help you easily identify the most environmentally-friendly products by comparing products of the same type (T-shirts, trousers, backpacks, etc). Decathlon is committed to displaying the environmental data of its products. For more information:

Product test
All our down jackets are laboratory tested with 5 km/h wind, worn as a 3rd layer on a thermal mannequin (over a long sleeved T-shirt and fleece). Their level of thermal insulation is measured on a scale of 1 to 5, enabling you to make the choice that best fits your use.

Good but feathers problem
Used for 2 to 8 weeks
Feathers coming out every time i wear it
Waste of time, don't bother. Ordered a 2XL for my father for christmas and when it came I was shocked at the size of this jacket. When I by Mens clothes I usually buy S or M and this ONLY just fit me... So there's no way on earth this can be 2XL.
Not just that, but I then discovered that I had to pay to return this item.
I couldn't find a phone number to talk to anyone so I had to waste a whole afternoon taking the item back to a store as it was very bulky and would have cost a fortune to post. I couldn't wait for an email reply as I need the money back to buy a new present.
Will not be buying clothes from Decathlon again as their sizing are clearly screwed up.
