Product Reviews

Very comfortable, light weight.am loving it
Really works in regions with down to -5 degree celsius temperature. Worked well in the Himalayas in December.
This product is same as looks in picture. Best for low temperature and very light in weight. Anyone can buy it without any quiry.
Great jacket but wow. 25% price increase from 39.99 to 49.99 is a bit much. It was really good value before, now its approaching the price of branded jackets. I notice the price on decathlon.fr is 50 euro. Bit disappointing to see Decathlon doing this. I appreciate prices rise but 25%?
Nice jacket but duck farm add more
If I could give this 6 stars out of 5 I would. The value here is off the charts. I challenge anyone to find an 800 to 850 fill down Jacket that is even within 100 dollars of this one. It's impossible to find another jacket with these specs for under 200 let alone 100. Aside from the specs this thing is the most comfortable jacket I have ever owned. It's the only hacker I have ever owned that doesn't feel restrictive around my shoulders/bust but yet doesnt look baggy. It literally feels like you arent wearing anything but yet you are warm. It's a strange feeling because of how light it is. This jacket even went on sale at one point for 50 bucks so I bought 2 more. Haha! Dont understand how this high of fill power can be sold at this price. Have never discovered a product that is this good of a value compared to the competition.
The jacket is very warm and the loft right out of the box was excellent! I double checked the seams, zippers, and all surfaces of the jacket and didn't see or feel any faults or loose feathers. It is exceptionally comfortable and easy to move around in. The cuffs are elastic and the hem is cinchable if you're thin to keep the wind out. It's not waterproof so I recommend a waterproof shell over it in prolonged wet conditions or a downpour. Love the pockets and zipper garage and the hood is very soft and form fitting which I feel helps it follow your head when you turn to look at something. Going to have to put the product through its paces to get a better feel for its performance but so far it's a 10/10 for me (especially compared to other jackets in this price range) and definitely going to find use both day to day and backpacking. Note: this jacket runs small. If you're a T-shirt size medium you should get the large of this jacket for standalone use and possibly the extra large if you're going to layer things under it (I may just end up getting 1 of each for these reasons. It's a darn good jacket).
Good Warmth, weight, and price. Sub par stitching. Already have loose strands throughout the jacket.
Exceptional quality. Runs very small. Normally wear an XL in the us, so I bought an XXL and I can't wear anything under it besides a base layer. The chest and torso are fine, but the arms are extremely narrow. I got excited and cut the tag, so it's too late to exchange for an XXXL
Very comfortable product
Light weight jacket I have never seen this before There is no need to wear more warmers while wear this jacket
Light and effective in keeping cold away.nice feel on the body
The jacket is light, has good loft and the stitching/sewing seems to be good quality - just as good as my more expensive down jacket from Patagonia’s. The design of the sleeve is bad. There is an elastic cuff but it is tucked and sewn to the end of sleeves essentially folding the sleeves. They should have left the sleeves with the elastic cuff at the end instead of folding it. Additionally, the sleeve length runs long. I’m 5”10 with above average wingspan and it’s still an inch long. You can view video reviews of this jacket online and notice the long sleeve length on those people too. Watch for the tucked sleeve at the end too. There is an elastic cuff not visible to the eye. Overall, I would still recommend it for the quality and price but wish they would update the sleeves and an inside chest zipper pocket would be nice.
Compact & light for camping & hiking
It was good until I washed it. Followed the washing instructions to the letter and... boom all the feathers ended up on the one side of the jacket,

How warm is this padded jacket?
This padded jacket, worn as a 3rd layer, has been certified for an active comfort temperature of -5°C during a standardised test in a thermal chamber.The model is wearing a synthetic long-sleeved t-shirt and a light fleece underneath. It works with a simulated 5 km/h wind.We have also tested this model in "static" mode; the comfort temperature is +5°C in this case.
The advantages of a duck down and feather filling
The filling power of down has 3 advantages for mountain sports:- Thermal insulation thanks to the air trapped in the down and feathers- Ultra lightweight: down is lighter than synthetic wadding while offering the same degree of warmth. This saves even more weight in your backpack- Ultra-compressible
How to measure the fill power of a down and feather wadding?
The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. It is expressed in CUIN (cubic inches).Down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation.For this down jacket with its 85% down/15% feathers filling, the fill power is guaranteed to be 800 CUIN or more (European standard).
* what is rds certification?
Thanks to our traceability system, we can guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers commit to using only feathers from ducks raised for their meat and plucked after slaughter.We have been awarded RDS certification (Responsible Down Standard) by a third-party organisation.http://developpement-durable.decathlon.com/documents-et-rapports/documents/

How to care for a down and feather jacket?
The down jacket can be worn throughout the winter and will certainly need to be washed. Follow our guidance by clicking on the link below:https://www.forclaz.co.uk/advice-alias/how-should-i-look-after-my-down-jacket-tp_2579In brief:1/ machine wash, 30°, with 2 or 3 tennis balls. Gentle spin cycle.2/ tumble dry with 2 or 3 tennis balls, repeat 2 or 3 times until it is completely dry
In case of rain
The material of the down jacket is water-repellent. It lets drops of water roll off the fabric, delaying water getting in the jacket and giving you time to find shelter. We nevertheless recommend wearing a waterproof jacket over the down jacket in the event of prolonged exposure to the rain.
Water-repellent property of component (not to be confused with waterproofing)
The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it.As a result, the fabric does not soak up water and stays light and warm.The fabric is made water-repellent by treating its outer surface, however this property may deteriorate with use.We recommend that you restore it after each wash.
How to restore water-repellent properties?
The water-repellent treatment becomes less effective with time, washing and use.Here is how to restore the water-repellent properties of your padded jacket!https://www.quechua.co.uk/advice/how-do-you-restore-water-repellent-properties-your-jacket-a_86426You can also use the care product: Treatment restoring water-repellent propertieshttps://www.decathlon.co.uk/txdirect-wash-in-300ml-id_8401685.html
