Product Customer Reviews
Jacket is very warm
I recommend
Very comfortable to wear, serves its purpose fully (insulates well against wind and cold), is very light and takes up little space to carry in a bag, still beautiful and practically like new after 1 year of frequent use.
Light, easy to pack compactly and warm. A plus for the slightly longer back.
comfortable jacket, quite warm, very practical, aesthetic, several colors, correct size
I washed the jacket at 30 degrees and it's completely ruined. There's a big ball inside at every seam. The fleece is in a ball and the rest of the jacket is flat. I'm disappointed, my daughters bought it for me for my birthday. Thank you.
Thin and warm down jacket suitable for temperatures around 5C°. Very light
The Decathlon Women's MT100 Trekking Down Jacket is a great choice for those looking for a warm, lightweight and easy-to-pack garment. Thanks to its integrated hood and compact design, it offers good thermal insulation, keeping the body warm even in cool weather. It is ideal for trekking and other outdoor activities in the mountains. The fit is comfortable, but can be slightly tight over other layers. Excellent value for money.
nice product against the cold, but better to avoid getting too wet!
It is a comfortable jacket, which is suitable both for going out in the city and for going to the mountains.
very light and warm, perfectly protects against wind
Warm but fitted model, very suitable for everyday use.
It keeps you warm without taking up too much space, it's perfect.
This down jacket looks good but I had to return it. My usual size didn't fit me because the cut is too narrow under the arms. The size above is too big on the rest of the body. This is something that is increasingly common on women's jackets in several departments (hiking, climbing, etc.). This was not the case before. It's a shame because it forces me to look elsewhere while the technicality is present at Decathlon. If the cuts could be reviewed...
Used in winter conditions during mountain hikes. As for me, it worked. Light, great under a trekking backpack. Successful purchase

Additional Product Information
Composition
Main fabric: 100.0% Polyamide ; Filling: 100.0% Polyester ; Main lining: 100.0% Polyamide
How warm is this padded jacket?
This down jacket, worn as a 3rd layer, has been certified for an active comfort temperature of 23°F (-5°C), during a standardized 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 3mph wind. We have also tested this model in static mode. The comfort temperature is 41°F (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.
Inflating power of down/feather filling
The fill power is a measure of the down fts thermal insulation capacity and its potential to InchtrapInch 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.
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 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.Our advice: 1/Machine wash with a detergent suitable for down or technical garments, at 30°C, 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.
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? this is how to repair your down jacket
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. We even have patches you can purchase on our website!
