I am using this jacket in 4° Tempreture in Uttrakhand with inner lining although we feel cold the claim it is suitable for -° is not correct The information should be correct by Manufacturer

Hello Rajesh

Thank you for your valuable review. We claim temperature rating on our products on the basis of the on ground product test done on a group of trekkers fully equipped in trekking gear with proper layering like base layer, mid/fleece layer, warm cap, gloves trekking boots etc. while active on a trek.

You might feel the sensation of cold if layering is not done properly or if you are in static condition.

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

Additional Product Information


Main fabric

  • 100% Polyamide

Main lining

  • 100% Polyamide


  • 100% Polyester cationic

What level of warmth does this padded jacket provide?

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.

Do you want to know more about the fill used?

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, it has high insulation properties thanks to the air trapped inside, and remains lightweight. 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 properties of the 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 soaking up water 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 renew 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 the water-repellent properties?

Follow the guide! We recommend that you use the dip-coating care product


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 mountain 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!
