kept me warm

I have a mountain w/h ghost whipser down jacket and I wanted another one but not at that price. I decided to give Decathalon a shot. The jacket has not disappointed me so far. I went snowshoeing with it in mid 30's degrees, cloudy conditions and only a base layer. So far i am satisfied with my purchase. It has kept me warm. If i repurchase I will most likely go back to Decathalon.


I needed a larger size than I would normally wear. I find it to be idea for casual wear. Nice and lightweight.

Thermal insulation - warmth

This padded jacket, worn as a 3rd layer, has been certified for an active comfort temperature of 23°F during a standardized test in a thermal chamber. The model is wearing a synthetic long sleeve T-shirt and a light fleece underneath. It works with a simulated 3 mph wind. In our heat comparison tool, it represents 2 stars. We have also tested this model in "static" mode; the comfort temperature is 41°F in this case.

Technical information on the fill

We use 100% polyester fill (70% recycled) weighing 4.4 oz/m² in the body and 3.5 oz/m² in the sleeves and hood. The fill is made from silicon-coated spiral fibers that make it highly compressible and highly durable. Despite its low thickness, the air trapped inside provides high insulation properties while allowing it to remain lightweight. It remains warm even when wet.

Durable materials

This polyamide fabric uses 20 denier thread and resists 20,000 cycles of abrasion. Martindale test, Standard 12947-2 Outer: 100% polyamide fabric 1.4 oz/m², 20 denier Lining: 100% polyamide fabric 1.2 oz/m², mix of 15 to 20 denier threads

Water-repellent property of component (not to be confused with waterproofing)

The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it. This prevents your padded jacket from soaking up water and keeps it lightweight and breathable. The fabric is made water-repellent by treating its outer surface; however, this property may deteriorate with use.

How to restore water-repellent properties?

The water-repellent treatment becomes less effective with time, washing, and use. Here is how to restore the water-repellent properties of your padded jacket! You can also use the care product: Treatment restoring water-repellent properties

What is a pfc-free water-repellent treatment?

Our water-repellent treatment is PFC-free. PFCs are used to make fabric water-repellent; however, they are toxic to the environment and people. By substituting PFCs with other technologies giving the same level of performance, we are reducing the environmental impact.

Do you know why the inner lining of your padded jacket is gray?

Because the fabric we use reduces CO2 emissions by 40%. The fabric used is innovative because it mixes a dope-dyed black yarn and an undyed yarn. Compared to a classic dyeing process, this process reduces by: • 66% fine particle emissions (PM2.5) • 74% Eutrophication of fresh water • 68% eutrophication of sea water

Additional sustainable development information

On the Trek 100 gray model, the outer fabric uses a clean process known as dope dyeing (the thread is dyed in bulk) reducing CO2 emissions by 36%. More information:

A score for comparing the products' environmental impact

The environmental impact of the product is calculated over its entire lifecycle and using different indicators. An overall ABCDE score is given to help you easily identify products with the best environmental performance by comparing products of the same type (T-shirts, pants, backpacks, etc.). Decathlon is committed to displaying the environmental information of its products. More information:



Product testing

In November 2017, 6 backpackers (4 men and 2 women) and part of the Forclaz design team tested this jacket for 4 days in the southern French Alps (Lus La Croix Haute). We were then able to make the final modifications and validate it for use for backpacking.
