Durable materials

This polyamide fabric that uses 20 denier thread resists 20 000 cycles of abrasion.
Martindale test, Standard 12 947-2
Outer: 100% polyamide fabric 39g/sqm, 20 denier
Lining: 100% polyamide fabric 35g/sqm, mix of 15 and 20 denier threads

Thermal insulation

This padded jacket has been certified for a comfort temperature of -6°C 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.

Technical information on the wadding

We use 100% polyester wadding (25% recycled) at 125g/sqm on the body and 100g/sqm on the sleeves and hood.
The wadding is made from silicon-coated spiral fibres that make it highly compressible and highly durable.
Despite its slim 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 padded jacket is grey?

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

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

A fabric's water-repellent property is its capacity to make water run off its surface without seeping in.
This prevents the fabric from soaking up water, keeping it lightweight and warm.
A fabric becomes water repellent by applying a treatment to its outer surface.
This treatment must be renewed throughout the garment's lifetime (recommended after every wash).
Products are available for this purpose in our stores.

How to restore the water-repellent property?

Follow the guide:


Inside flap under the zip 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.
Hood with elastic bias binding
