Light Weight And Warm

a compact down jacket which easily folds away in its left hand pocket using a zip with double puller. I bought M size which is only 273 grams. Its outer fabric is water repellent which prevents water from getting in.

Got torn off easily

I wore it on a trek and on day one it got a cut on my arm and the stuffing started coming out. I had to put a cellotape and wrap a piece of cloth around it to prevent it from further damage. I cannot wear it again and it is not at all a durable product. I hope i can get it exchanged so that i can wear it in winters atleast when I’m in delhi.

Excellent Down Jacket

I watched lots of reviews and was not entirely convinced that this jacket would be as good as it appeared to be, especially for the price. I decided to purchase online, fully expecting to return it. It is superb. Super warm, super lightweight, excellent fit. Even the colour, which on the screen I thought looked a bit garish, is fine. A brilliant product enhanced by the fact that it packs into its own pocket. Feel delighted that I have a down jacket without breaking the bank.

Great coat, wish they did grey though!

Great coat. Been wearing it to a trip to Belfast. Great that it packs down easily in its own pocket, very convenient! Also loveeee the big pockets! Not something you get often with most coats/jackets. Been wearing it in the rain -- does keep the water out! Only have an issue with the colours. I bought the blue but find the colours really garish. I struggle to find things that match my blue coat :( the navy blue is ok but looks too shiny so went for the lighter blue. I wish they did a more neutral colour for the more plainer girls. They do a grey in the men's so why not the women

Perfect for winters

Light weighted & fully warm.. it’s worth buying..

Value for money.

Comfortable, trendy, bold and warm enough to brave the Delhi chill... Recommended.

Was not warm as you claim

I bought this jacket for my trip to Russia. This jacket was not effective in delhi where it was 10 degrees temperature. I was not fit even for 1 degree in Moscow even after wearing thermals and fleece inside. I would want to return this product, after paying a high price its not at all worth it.

Hello Aesha,

Thank you for taking out time to give your valuable feedback. We are sorry that you were not satisfied with the product. We communicate about the temperature rating on our jackets after a field test on different individuals as the feeling of cold is subjective. The test is done with full layering and panoply i.e with Base layer, Fleece Layer (Layer 2), Warm hat, Warm socks, Trekking gloves, Trekking boots etc and the test is done during trek when the body is active and releasing heat. Hence for a normal trip when you are not using proper panoply and you are not trekking/ are active the temperature rating will not be -5 degree which we communicate.

However, If you feel the product did not solve the purpose, We apologize for not being able to suggest the right product at the time of purchase, Please feel free to return or exchange the product at your nearest Decathlon store.

I hope the information was helpful. Kindly write back to me in case of any further queries.

Not enough for temperature below zero degrees

The jacket itself will not suffice for a temperature below 0 degrees Celsius. A go layer of thermals is mandatory to make one feel comfortable. Otherwise the jacket is lightweight and of good quality.

Additional Product Information



  • 85% Grey duck down
  • 15% Grey duck feather

Main fabric

  • 100% Polyamide

Main lining

  • 100% Polyamide

Padding - Inner fabric

  • 100% Polyester cationic

Feather origin

Thanks to our traceability system, we can guarantee the origin of the feathers, in compliance with our commitment to use responsibly sourced materials. Our suppliers are committed to using only feathers that come from ducks that are bred for their meat and are plucked after slaughtering.

Fill power of the down/feather filling

For this down jacket with its 85/15 filling, the fill power is guaranteed to be 800 CUIN or more (European standard). The fill power is a measure of the down's thermal insulation capacity and its potential to "trap" air. So, down with a higher fill power (high CUIN number) will occupy more space, trap more air and provide greater thermal insulation.

Weight of the filling

XXS: 2.4 oz XS: 2.5 oz S: 2.7 oz M: 3.1 oz L: 3.4 oz. XL: 3.5 oz

The advantages of a duck down and feather filling

The down's long-lasting fill power gives it 3 important qualities for hiking: - Thermal insulation thanks to the air trapped in the down and feathers - Ultra-lightweight: to provide equal warmth, feathers are lighter than synthetic padding. This saves even more weight in your backpack - Ultra-compressible

Care instructions for jackets filled with down and feathers

The down jacket can be worn throughout the winter and will certainly need to be washed. Follow the instructions by clicking the link below:

In the event of rain

The fabric of this down jacket is water-repellent. It makes drops of water run off the surface, which delays the time it takes for water to get inside the down jacket, giving you time to get out of the rain. However, we advise you to wear a waterproof jacket over the down jacket in case of prolonged exposure to rain.

How to reactivate the water-repellent property?

Follow the guide: And use the care product: Wash-in waterproofing product that restores the water-repellent properties It restores the water-repellent properties of the fabric and optimizes the performance of your garment throughout its lifetime.

A score for comparing the products' environmental impact

The product's environmental impact is calculated over its entire lifecycle using different indicators. An overall ABCDE rating is given to help you easily identify products with the best environmental performance by comparing and contrasting products of the same type (T-shirts, pants, backpacks, etc.). Decathlon actively promotes this environmental rating initiative. For more information:



Product testing

All our down jackets are laboratory tested with 3 mph wind, worn as a 3rd layer on a thermal mannequin (over a long-sleeved T-shirt and fleece). Their level of thermal insulation is measured on a scale of 1 to 5, so that you can make the choice that best suits your use.
