Technical Information

Feather origin
We are committed to being responsible for our production, we have decided to work only with RDS certified suppliers (Responsible Down Standard Certified) that guarantee that the down and feathers used come from ducks and geese bread for their meat, and treated without cruelty. For more information:
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 takes up more space, trapping more air and providing greater thermal insulation.
Weight of the filling
S: 190 g M: 200 g L: 210 g XL: 223 g 2XL: 236 g 3XL: 249 g
The advantages of 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

In the event of rain
The material of this padded jacket is water-repellent. It makes 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. The shoulders and hood of the down jacket, which are more exposed to the rain, are waterproof. However, we advise you to wear a waterproof jacket over the down jacket in case of prolonged exposure to rain.
SizesS to XXXL.

Very warm and value for money
Used for 2 to 8 weeks
This jacket is value for money. Rolls into a nice little fluffy ball during travel trips. Keeps me warm at 0 degrees Celsius. Couldn't ask for anything more. I wear a 42 size shirt in India but had to buy M size of this jacket.
Excellent Product
Used for 2 to 8 weeks
Just excellent product. I used this product on a winter expedition to Ladakh where minimum Temp was -10C.
It helps me to withstand extreme cold such as -30C.
Perfect for Iceland trip
Used for 2 to 8 weeks
I spent a week working and filming in Iceland at the start of March temp range -2C – -13C plus windchill. Great just out and about, then wore it under a Berghaus Goretex waterproof over a fleece and base layer while at altitude and never suffered. Minimal down leakage, didn't have any problems with fabric tearing as another reviewer reported. Only minor issue is pockets are slightly at the wrong angle so if you forget to zip them back up contents are at risk.

Very warm
Excellent jacket
Used for 3 to 6 months
This is a really good jacket and well worth the money. Performs like a jacket twice the price. Usual thing with Decathlon, buy a size bigger (I'm a large and went for the XL - fits like a glove). don't concur with the earlier comments about the elbows. Not an issue. Only down side is that there are no toggles on the hood to draw it down and keep it there. Apart from that, just great
Great warmth but very fragile
Used for 2 to 8 weeks
This is a fanatically warm and comfortable jacket with surprisingly good water resistance. But it has onr major flaw. Apart from the areas reinforced with ripstop material, the main fabric is incredibly fragile. More fragile than any other down jacket I have owned. After just a few days of light wear an abrasion from the zip of the jacket itself caused a minor knick in the fabric and now feathers are leaking out. It’s potentially a great product but areas of the fabric are so fragile I’m afraid to wear it even in light day to day use.

Now exploring repair options.
Used for 7 to 12 months
If this jacket had Rab or Mountain Equipment printed on the front it would be selling for £200. Absolutely brilliant jacket which is just as good as any of the top brands at a fraction of the price. The only way it could be improved is if they used a ripstop fabric for the whole jacket rather than just the shoulders, wrists and hood.
Very warm
Used for 3 to 6 months
A very warm jacket for the price. A bit confused by some of the more negative reviews. The jacket does not proclaim to be robustly waterproof which is normal for this type of product. For energetic out door activity it would be far too warm. The comment about clumping of down may be true if the cleaning instructions are not adhered to. I'd see this as a great jacket for keeping warm when not moving ie camping, waiting for buses trains etc.
Highly Recommend
Used for 2 to 8 weeks
Love this jacket.
Warm and wind proof in all conditions.
From multiple layers down to the one jacket for me this is the jacket I have been looking for for years.
Will I buy again. Yes.
Would I recommend. Already doing.
