Our team of mountain trekking enthusiasts has developed this padded jacket for trekking in comfort in cooler weather Thin and warm, it is our most eco-designed mountain trekking down jacket!

Technical Information

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 39g/sqm, 20 denier
Lining: 100% polyester fabric 35g/sqm, mix of 15 to 20 denier threads

Thermal insulation

This padded jacket, worn as a 3rd layer, has been certified for a comfort temperature of -5° during a standardised test in a thermal chamber.
The mannequin wears a synthetic long-sleeved t-shirt and a light fleece underneath. It walks with a simulated 5 km/h wind.
In our heat comparison tool, it represents 2 stars.
We have also tested this model in "static" mode; the comfort temperature is +5° in this case.

Technical information on the wadding

We use 100% polyester wadding (70% recycled).
The wadding is made from silicon-coated spiral fibres that make it highly compressible and highly durable.
Despite its thin design, it is highly insulating thanks to the air trapped inside and it remains low weight.
It remains warm even when wet.

Do you know why the inner lining of your down jacket is grey?

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 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%

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 zip that protects you 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.
