Men’s mountain trekking down jacket

Over the moon with this jacket! It’s very sharp looking, lightweight and warm! One more could you ask for!

Absolutely over the moon with this jacket

Mostly good. Shell fabric prone to wearing away.

You get a lot for your money with this jacket. As a medium warmth UK winter jacket, It's great in many ways. The downside is that the shell fabric tends to wear away in places where it rubs against itself - so there are now holes on the sleeves / wrist area. Also on the waist cord area. Through these holes down/feather fill is lost. I've had other down jackets that didn't do this. Now after 2 years I'm in the process of looking for a new jacket. If the shell fabric was better I'd give this 5/5.

got faults shame

im xl bought this very snug more large short in the body too it would benefit longer at rear for back movement and sleeve extenders cheap mods but wow this would be an amazing bit of kit for sure

Good value

Great jacket, nice and warm but very lightweight, water resistance is good if caught in an unexpected light shower, but obviously it’s not fully waterproof.

Brilliantly warm

This jacket was slightly more than I wanted to pay but it is money very well spent. It is so warm that I have just been to the States where I was in the coldest weather I have experienced this winter and with just 1 layer underneath I was very comfortable. I found the sizing strange as I had to purchase a large when normally I am a medium and most of the Decathlon jackets I tried were way too small on the hips .


Really good jacket keeps me warm in all weathers, my only criticism is the delivery as they said it had been delivered when it hadn’t. I assume they do this to meet targets then just deliver the next day, thankfully I wasn’t desperate for it.

Son Coat

Nice and warm, plus squashes down to nothing. Son loves it.

It's ok, light and comfy, I personally don't find it particularly insulating for British winter use.

Top value

I liked this coat so much I bought another one after I damaged the original.

Survived a Canadian winter!

This coat is incredible. Kept me warm and dry over just a shirt and T-shirt in Canada’s -36c polar storms!

Warm jacket

Good warm jacket, not as bulky as I expected. Good value for money and well made

How warm is this padded jacket?

This padded jacket, worn as a 3rd layer, has been certified for an active comfort temperature of -10°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 0°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/15% feathers filling, the fill power is guaranteed to be 660 CUIN or more (European standard).

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.To find out more:

How to care for a down jacket?

The down jacket can be worn throughout the winter and will certainly need to be washed. Follow our guidance by copying the link below: summary:1/ machine wash, 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 repair your fleece?

A tear on a padded jacket can happen when trekking! The good news is that it can be repaired so the tear doesn’t get any bigger or to stop the feathers from escaping.Don't you feel at ease carrying out this repair yourself? Don't worry! Our in-store Decathlon workshops offer a repair service to mend your padded jacket using a heat-bonded patch.

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 do i reactivate the waterproofing 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
