Quality of the product is not so good .

Excellent. Only suggestion that inner pockets must be added.

Excellent Jacket

Using decathlon for the first time. The jacket is really nice, warm and ultra light weight. Loved it. Hope you guys will start 'Change product' option soon, so that a person can change size, if required.

Pocket Enhancement

There should be little more depth in pocket and the material of pocket not to be silky. A worry that the chance of scratch is significant because of the type of material. But my comment could be premature. As I am new user.


So warm and cozy. After all I must say this is so authentic and so comfortable.

Additional Product Information


Main fabric

  • 100% Polyamide

Main lining

  • 100% Polyamide


  • 100% Polyester cationic

How warm is this padded jacket?

This padded jacket, when worn as a 3rd layer, has a temperature rating of 23°F that was certified during a standardized test in a thermal chamber. The model wears a synthetic long-sleeved T-shirt and a light fleece underneath. It works with a simulated 3 mph wind. We also tested this model under "static" conditions; its temperature rating is 41°F in this case.

Want to know more about the fill?

We use 100% polyester padding (70% recycled). The fill is made from silicon-coated spiral fibers that make it highly compressible and highly durable. Despite its low thickness and light weight, the air trapped inside gives it high insulation properties. It retains its warmth even when wet.

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 self-dyed black thread and an undyed thread. Compared to a conventional 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 black and Trek 100 blue models, the outer fabric uses a clean process known as dope dyeing (the thread is dyed before the yarn is woven) reducing CO2 emissions by 36% More information:

Durable materials

This polyamide fabric that uses 20 denier thread can withstand 20,000 abrasion cycles. Martindale test, 12947-2 standard Outer: 100% polyamide fabric 1.4 oz/sqm, 20 denier Lining: 100% polyester fabric 1.2 oz/sqm, mix of 15 to 20 denier threads

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

A fabric is water-repellent when it allows water slide over its surface without seeping in. This prevents the fabric from swelling and keeps it lightweight and warm. 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

Pfc-free water-repellent treatment

On the Trek 100 padded jacket, the water-repellent treatment doesn't contain PFCs (perfluorocarbons), i.e. it is PFC-Free. PFCs are used to make a fabric water-repellent, but they are very toxic for the environment and people. By replacing the PFCs with other technologies that we are developing to enable the same level of performance, we are helping to reduce this environmental impact.

How to restore water-repellent properties?

Follow the guide! We recommend that you use the care product to treat and restore water-repellent properties


Inside flap under the zipper that protects from the wind. Elasticated cuffs Flap at the top of the collar to protect the chin. Tightening with an elastic cord and toggle at the hem.

A score for comparing products' environmental impact

The environmental impact of the product is calculated based on its entire lifecycle and using different indicators. A general score from A to E is provided to help you easily identify the most eco-friendly products by comparing products of the same type (T-shirts, pants, backpacks, etc). Decathlon is committed to displaying this environmental information. More information:



Product testing

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

Storage instructions

In order to preserve all the padding's fill power, store your padded jacket on a hanger rather than stuffing it in its pouch!
