Our team of mountain trekking enthusiasts designed this feather down jacket for bivouacking in cold weather. The most compact RDS certified down and feather jacket which combines warmth and lightweight!

Technical Information

Feather origin

Ethical down certified by RDS (Responsible Down Standard).
Thanks to our traceability system, we can guarantee the origin of the feathers, in compliance with our commitment to use responsibly sourced 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 the down/feather filling

For this jacket filled with 85% down / 15% feathers, the fill power is guaranteed to be 800 CUIN (European standard)
The fill power is the capacity of the down to insulate by "trapping" a certain volume of air. 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.

Weight of the filling

XS: 82 g
S: 88 g
M: 94 g
L: 101 g
XL: 108 g
2XL: 115 g
3XL: 124 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: to provide equal warmth, feathers are 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:

Thermal insulation

This padded jacket, worn as a 3rd layer, has been certified for a comfort temperature of -5° during a standardised test in a thermal chamber.
The mannequin wears a synthetic long-sleeved t-shirt and a light fleece underneath. It walks with a simulated 5 km/h wind.
In our heat comparison tool, it represents 2 stars.
We have also tested this model in "static" mode; the comfort temperature is +5° in this case.

In the event of rain

The fabric of this down jacket is water repellent. It enables 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.

How to reactivate the water repellent property?

Follow the guide:
And use the care product: Wash-in waterproofing product that restores the water repellent properties
It restores the water repellent properties of the fabric and optimises the performance of your garment throughout its lifetime.

A score for comparing products' environmental impact

The product's environmental impact is calculated over its entire life cycle using different indicators.
An overall ABCDE rating is given to help you easily identify products with the best environmental performance by comparing and contrasting products of the same type (T-shirts, trousers, backpacks, etc.).
Decathlon actively promotes this environmental rating initiative.
