Product Customer Reviews

Comfortable soft, pleasant to wear. This is the 2nd purchase, we had already purchased 3 years ago.
Nice
Good
It took it to the mountain hike it kept me cold although it is claimed a -5℃ weather jacket. Remember to keep a fleece along with it
corresponds to the item I was looking for
He's a good boss
Very nice article
The only thing is that when you wash it and centrifuge it, the filling moves.! And then it doesn't isolate the same!
The jacket is good, I use it as a base layer under a Gore cycling jacket, the day was -1 degrees and this was borderline for me. But overall I'm super happy with the jacket; for the price you can't go wrong.
OK
Very good value for money
Overall its a good product!!!
Perfect!
I recommend it excellent quality price
When I bought this jacket, I didn't expect anything. Just a cheap down jacket, definitely useless. The price was tempting, I needed a light insulating layer, I bought it online so I had no contact with the product before purchasing. When the parcel arrived, it was a shock - light as a feather and much warmer than its appearance suggests. Additionally, it packs ultra-compactly. The outer fabric feels delicate, but I don't plan on using it outdoors without the outer layer, so it shouldn't be a problem. Similarly with hydrophobicity...

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). So, down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation. This puffer jacket, filled with 90% down and 10% feathers, has a guaranteed fill power of 800 CUIN (international standard) or over.
What is rds certification?
RDS or “Responsible Down Standard” is a worldwide certification issued by an independent organisation to volunteer brands.This standard enables us to guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers commit to using only feathers from geese and ducks raised for their meat and slaughtered before down and feathers are collected.
How to care for a down jacket?
The down jacket can be worn throughout the winter and will certainly need to be washed. But the less you wash it, the more it will retain its thermal insulation and water repellency.Summary: 1/Machine wash with a detergent suitable for down or technical garments, at 30°, with 2 or 3 tennis balls. Gentle spin cycle. 2/ tumble dry with 2 or 3 tennis balls, and repeat 2 or 3 times until it is completely dry.
Water-repellent property of component (not to be confused with waterproofing)
The water repellent property of a fabric is its ability to make water run off its surface without absorbing it. This prevents the fabric from swelling, and keeps it lightweight and warm. The fabric of this down jacket is water repellent, however, we recommend that you wear a waterproof jacket over it in the rain. The fabric is made water-repellent by treating (PFC-free) its outer surface, however this property may deteriorate with use. We recommend that you restore it after each wash.
How to restore the water-repellent properties?
Once you have cleaned your padded jacket, we recommend you use a water-repellent reactivator spray to preserve the hydrophobic properties of the outer fabric. This renews the fabric’s water repellent properties and optimises its performance throughout the lifespan of your garment.
A snag? how to repair your fleece
A tear on a padded jacket can happen when trekking! The good news is that it can be repaired with a repair patch to prevent the tear from getting bigger or feathers from escaping. Don't you feel at ease carrying out this repair yourself? Don't worry! Some Decathlon workshops offer an in-store repair service to mend your padded jacket using a heat-bonded patch.
