Buy 2 sizes bigger

Size comes up very small. A small criticism on many Decathlon goods is that the ladies sizes aren't as generous as gents equivalent.

Excellent very warm

I bought this as I work outside a d needed something very warm over winter. I’d already bought a couple of others for other retailers but none were half the jacket this is! I’ll definitely buy another and highly recommend. A bit bulky but snug and warm!

Small on the sizing

It’s a bit small on the sizing and fits very neat even though I went for a size bigger. Great jacket though and keeps you really warm.

value for money

Daughter found it adequately warm and comfortable for Delhi winter (upto 3℃). Attractive style and perfect size.

Great little jacket

Really great little jacket, perfect for someone who feels the cold a lot (like me), fits well, and is lovely and light. It comes with a little bag to pack it down into, the only thing is I end up putting this in the pocket which I then keep zipped up for fear of losing it. A place to store it within the coat would be amazing. And the addition of an internal pocket would make it faultless, but aside from that I love it.

Warm and packs down small.

Purchased for my teenage daughters trip to New York. She loved the warmth the ability to pack it small and the styling.

Additional Product Information



  • 85% Grey duck down
  • 15% Grey duck feather


  • 100% Polyamide

Main fabric

  • 100% Polyester cationic

Feather origin

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 are plucked after slaughtering.

Fill power of the down/feather filling

This 85% down / 15% feather down jacket has a guaranteed fill power equal or above 660 CUIN (European standard). The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" 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

XXS: 4.1 oz XS: 4.4 oz S: 4.6 oz M: 4.8 oz L: 5.2 oz XL: 5.5 oz

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 padding. 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: How to wash and dry your down jacket

In the event of rain

The fabric of this down 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. The down jacket is not waterproof. We therefore recommend you wear a waterproof jacket above the down jacket if you are under the rain for a long period.

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 optimizes the performance of your garment throughout its lifetime.

A score for comparing the products' environmental impact

The product's environmental impact is calculated over its entire lifecycle 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, pants, backpacks, etc.). Decathlon actively promotes this environmental rating initiative. For more information:



Product testing

All our down jackets are laboratory tested with 3 mph 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, so that you can make the choice that best suits your use.

Storage instructions

Store on a hanger in a clean and dry place

Care instructions

Caring for down jackets requires special attention. We recommend using specialist dry cleaning services to maintain your down jacket. Machine wash at 86°F; add 2 tennis balls to restore the loft of the down. Rinse twice. Tumble dry (strongly recommended): synthetic cycle with 3 tennis balls to restore the loft of the down; for several cycles until the down has dried completely, to prevent the feathers from clumping and reducing insulating power. See the care instructions in the online guide
