Thermal insulation - Warmth
This padded jacket, worn as a 3rd layer, has been certified for an active comfort temperature of -5°C during a standardised test in a thermal chamber. The model is wearing a synthetic long-sleeved T-shirt and a light fleece underneath. It works 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°C in this case.
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
Water repellent property of component (not to be confused with waterproofing)
The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it. This prevents your padded jacket 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.
How to restore water-repellent properties?
The water-repellent treatment becomes less effective with time, washing and use. Here is how to restore the water-repellent properties of your padded jacket! https://www.forclaz.uk You can also use the care product: Treatment restoring water-repellency https://www.decathlon.co.uk/p/fabric-waterproofing-liquid-250-ml/_/R-p-308192
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.
Do you know why the inner lining of your padded jacket is grey?
Because the fabric we use reduces CO2 emissions by 40% of the component in question. The fabric used 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
On the Trek 100 grey padded jacket, the outer fabric uses a clean process known as dope dyeing (mass pigmentation of the thread) reducing CO2 emissions by 36% More information: http://sustainability.decathlon.com/
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.
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 score for comparing products' environmental impact

Product test
In November 2017, 6 trekkers (4 men and 2 women) with part of the Forclaz design team tested this padded jacket for four days in the Southern French Alps. We were then able to make the final modifications and validate it for use for mountain trekking.
