warm and lightweight

I've never had a down coat before. this is my first. I'm really happy with it. I haven't used it hiking or camping yet, but I've warn it in some cold weather. Specifically waiting to pick up my kid at school. The other parents looked really cold. i was nice and warm. My only down side (pun intended) is that when i sit in a chair in the cold, since the down gets compressed, my back is cold. there's no isupation when the insulation is flattened. i don't know if this is a common thing with down jackets, but it's an issue with this one. Makes me feel the need to use a pad on my back when I sit in a chair.

Superior warmth; great price!

In order to test the effectiveness of a winter jacket I always test with only a thin t-shirt underneath. This enables me to test its effectiveness without the additional effect of layering. Today was 37 degrees with 10-15mph sustained winds. I sat on a hillside with no windbreaks for 30 minutes. (I want to know if a jacket will keep me warm with no physical activity.) This jacket provided superior warmth! I never had to put on the hood which would’ve made me even warmer. It’s definitely a winter coat and it would be too much coat for a warmer temp day. The fabric is very lightweight (which is why I purchased it) and I wouldn’t wear this coat while trekking through a wooded area where it might snag and tear. It would be perfect once you’ve arrived at camp. It would also make a great jacket for a cold winter walk or watching an outdoor winter sporting event where you are sitting and need to stay warm. This jacket is a great deal at this price point! (I own winter jackets at double this price point.). I highly recommend it!

very warm

Very warm down jacket, with good cuffs and hood. Quite stylish colour and design.

Comfortable and warm

The jacket hit the right note for the beginning of July - entering mid-winter and those low teens degC. I'd purchased on line (and collected as 'contact-less pickup) but it proved to be too small and, as soon as lockdown was finished, I popped down to my local shop and exchanged it for the large size. That was better - proper arm length, stretch across the shoulders and plenty below the waist. No issue with changing. I've used it for outside in the air-type activities - walking, etc. it's simply too hot inside the jacket if you're inside the car or the mall. It will push down into a small plastic shopping bag for handling in the car, etc. Otherwise it's full-size and may get damaged if simply hanging around. Equally as good it came with 50% discount.

Punches well above its weight

Would expect to pay 3-4 times as much for an equivalent jacket from a big name brand or cottage manufacturer. So happy with this purchase.

"Feather" Weight and Cold Ready!

Excuse the pun in the title given it is mostly down insulation, but this jacket just plain great! Whether standing around outside, walking the dogs or beating into the wind of a winter storm, it keeps me warm. The side zippered vents are a nice touch to help keep from getting overheated and damp - something you want to avoid in winter. Sadly I snagged the last XL in stock in Ottawa, so hopefully there are more on the way!

One Flaw

Great jacket if you are looking for a stylish, warm layer to wear during the shoulder seasons. However I would keep it that, as a stylish jacket. Wear it around town, but not to the mountains where there are trees with branches. The material isn't all that durable, and snags very easily. Not for technical use.

Really Good Coat

I recently did a trip up in the Arctic hiking and camping in temperatures below -19degC. this jacket was perfect. I did contemplate buying myself a more expensive Rab jacket and I am so glad I didn't. This is a coat which is excellent value for money.

Battle tested at high altitude in Nepal

Bought this for my trip to Nepal where I was going over 3 high passes and summited 3 peaks (max altitude 5600m). This jacket was brilliant, very, very warm, but lightweight and packed down to a small size thanks to it's built in pocket storage. Particularly good on a very cold overnight camp at 4800m, a pre dawn hike up to 5400m to see the sunrise and a hike up to 5600m to see the sun set on Everest. Extremely cold during these times but the jacket kept me comfortable and warm. Now wearing it back home in Scotland during this current cold spell and it's ideal. Highly recommend.

Fragile and tears easily

Decathlon stand for good quality, and are a brand I return to again and again. HOWEVER Unfortunately this jacket does not come up to standard. WITHIN ONE WEEK, and after a trek, a huge tear was caused when the jacket brushed against a thorn bush. Literally just brushed against it. The down filling started to spill out of it, like a snow storm. I persevered, and hand stitched the garment. I returned to Decathlon, with a view to speaking to customer service, and COULD NOT GET CONTACT DETAILS FOR CUSTOMER SERVICE. I like the jacket, and continued to wear it for walk. Within another two weeks, on a trek in the woods, ANOTHER TEAR APPEARED, and down started to spill out again. This jacket is £109 and it has no strength, AND IS NOT OF MERCANTABLE QUALITY. I’m sure it would be fine if it never touched anything at all, and by that I mean, it lived in a vacuum, in outer space. It is warm It fits nicely However the material will not withstand any brush against thorn or stone etc. I am disappointed to say the quality of the outer layer is poor. I am waiting to hear from customer service, who have my contact details. I am happy to give them feedback, and return the now useless product. I am not asking to a refund. I continue to use Decathlon as I like the brand, however this item should receive less than one star.


Great jacket for the price. Pretty warm too.

Mountain Trekking Down Jacket

We bought these jackets on the recommendation of a Canadian outdoor person. We have used them for over a month now during the previous colder weather in Mancheter. The jackets are warm with a good fit and well made with excellent zips and reinforced wear areas. They are exceptionally good for the price. We also have jackets from Rab & Mountain Hardware to compare.

Additional Product Information


Padding: 85.0% Grey Duck Down, 15.0% Grey Duck Feather ; Main fabric: 100.0% Polyamide ; Lining: 100.0% Polyamide ; Yoke: 100.0% Polyamide ; Membrane: 100.0% Polyurethane ; Pocket: 74.0% Polyester, 26.0% Elastane

How warm is this padded jacket?

This down jacket, worn as a 3rd layer, has been certified for an active comfort temperature of -18°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 low weight: 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. For this down jacket with its 85% down and 15% feathers filling, the fill power is guaranteed to be 660 CUIN or more (international standard).

Reducing the risk of feather loss

The main stitching of the compartments containing the down and feather are heat-sealed to prevent the loss of feathers

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.

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 material of this down jacket is water-repellent; we recommend wearing a waterproof jacket over it in the event of prolonged exposure to rain.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 care for a down jacket?

The down jacket can be worn throughout the winter and will certainly need to be washed. Our advice: 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.

How to restore 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. 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.

Storage instructions
