Technical information on the wadding

We use 100% polyester wadding (70% recycled) weighing 125 g/sqm in the body and 100 g/sqm in the sleeves and hood.

The wadding is made from silicone-coated spiral fibres 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.

Durable materials

This polyamide fabric that uses 20 denier thread can withstand 20,000 abrasion cycles.
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

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 of this lining is innovative because it mixes a dope-dyed black yarn and an undyed yarn.
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

Our efforts to reduce our carbon footprint

On the black Trek 100 model, the outer fabric uses a clean dyeing process known as dope dyeing (the thread is dyed before the yarn is woven) reducing CO2 emissions by 36%.

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 water repellent property is achieved by treating the fabric's exterior. This treatment must be renewed throughout the garment's lifespan (recommended after each wash).
Products are available for this purpose in our stores

What is a PFC-free water-repellent treatment?

Our water-repellent treatment is PFC-free.

PFCs are used to make fabric water-repellent, however they are toxic to the environment and people. By substituting PFCs with other technologies giving the same level of performance, we are reducing the environmental impact.

Valuable advice for improving the durability of your down jacket!

In general, do not wash a down jacket too frequently because each wash decreases its thermal properties.


A tear on a padded jacket can happen when trekking and the good news is it can be repaired! You can either mend it or apply a heat-bonded patch so that the tear doesn't get any bigger and the synthetic fibres escape.
Don't you feel at ease carrying out this repair yourself? Don't worry! Our in-store Decathlon workshops offer a repair service for your padded jackets.
