Very warm and comfortable jacket. Nice fitting. Packs down into a small stow-away sack for easy travel.

Coat of dreams

I have previously owned a down jacket from Decathlon, which I wore to death over the last two winters. Even though this new coat cost £149, which I thought was a lot at the time, I now realise where the money has been spent. The fit is just right for my average 42” chest and it’s extra length so is great for keeping the cold off your rear end. It actually fits into it’s stow away pocket, that’s also fleece lined. The hood is a great fit, that doesn’t need adjusting to keep off your eyes. Plenty of large, sturdy pockets. So warm that it feels like you’re in front of a log fire whilst out in the snow. My conclusion is Decathlon have excelled themselves in designing what can only be described as a ‘Coat of Dreams’

Warmest down jacket ever

I ordered this jacket right after seeing it mentioned in the Financial Times HTSI Weekend section. The sensation of warmth is immediate; it has zips and pockets in all the right places, and is well designed for freedom of movement while doing sports. It is not compress to a size as small as a Uniqlo down jacket, but because of the superior quality (which is important for winter sports), I do not mind it taking up a little more space. The colour is perfect for staying visible in snowy conditions, or to be seen from a distance on the ski slopes!

Men's down jacket

Good quality jacket, pockets well placed and easy to use with gloves. Design is longer than other down jackets I have owned, this is a good feature... Well pleased with the overall performance of the jacket

Very comfortable and warm. As you would expect this to be lightweight and soft to the feel, tested and does the job.

Used in arctic exped and Kyrg exped winter. Great.

Have used this for a season on various winter splitboarding trips. Been down to -25c and was toasty warm where friends were shivering in other brands. Love this coat. Packs small. Light enough to bring everywhere.

Recommended to visit old soviet countries

Discovered the jacket by a famous YouTuber

Very comfortable, lightweight and protective

I have used this duck down jacket for 2 winter seasons in Boston, US and northeastern states. The temperature often goes below -20 degree C in winter here. The design of this jacket is so perfect that I absolutely didn't face any issues during winter with this jacket on. Sometimes I would just wear a half sleeve shirt inside and still would feel comfortable. The only drawback is, this jacket is NOT waterproof/ water-resistant. It'll get soaked in water quickly, which would be undesirable. So, you may have to remove the accumulated snow over it (during snowstorms etc). I also have washed this jacket in a laundromat washer and dryer. No issues there too.

Great jacket

Great Jacket what more can I say
