Seems ok

Not yet worn but looks ok. What was asked for

Would be nicer in pale grey

Nice gilet but would even better if we could have it in pale grey like the trek 100 padded jacket

Warm & light

Really pleased with my gilet - brilliant for under a waterproof & looks smart when worn with jeans etc. Hardly any weight to it so perfect as an additional layer if needed - good pockets too.

Good value

Good quality, lightweight and warm. Product arrived very promptly.

Warm and unbulky

I have a much more expensive gilet which I wear infrequently because I don't want to ruin it and it is pretty bulky so I thought I'd try buying this one to wear for work where it will get quite a bit of battering and be worn most days in winter. It did not disappoint and now I am hoping I get bought another one for Christmas to keep at home to wear too!

Nice gilet for women

My wife bought it recently and so far it has been a good experience for her. The cut and finish is good. It's definitely warm enough for our climatic condition and highly portable and lightweight. How will it fare in the long run, I don't know yet, but so far it has been a promising start.

Additional Product Information


Main fabric

  • 100% Polyamide

Main lining

  • 100% Polyamide


  • 100% Polyester cationic

Durable materials

This polyamide fabric that uses 20 denier thread resists 20,000 cycles of abrasion. Martindale test, Standard 12947-2 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

Technical information on the padding

We use 100% polyester fill (25% 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 remains warm even when wet.

Do you know why the inner lining of your down 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 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 black model, 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:

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

The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it. This prevents the fabric 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. In order to reactivate it, follow the guide:


Inside flap under the zipper that protects from the wind. Elasticated cuffs, Soft fabric 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 the products' environmental impact

The product's environmental impact is calculated over its entire lifecycle using various 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. More information:



Product testing

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