Technical Information

Check out the eco-design of this padded jacket!
The filling of this padded jacket is made from 70% recycled polyester fibres. For the lining, we use a “bi-ton” dyeing process where only one thread in every two is dyed. This dyed thread is also the result of dope dyeing which incorporates the colour pigments from the initial thread manufacture to avoid the use of dyeing baths and reduce our water consumption. This process can reduce CO2 emissions by 40% compared to traditional dyeing methods.
Additional sustainable development information
With the black MT100 and blue MT100 model, the outer fabric uses a special dyeing process called “Doped Dyeing” (the thread is dyed before being spun into yarn), helping us to reduce CO2 emissions by 36% More information:
How warm is this padded jacket?
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. We have also tested this model in "static" mode, the comfort temperature is +5°C in this case.
Want to know more about the wadding?
We use 100% polyester wadding (70% recycled). 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, 12947-2 standard 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 ability to make water run off its surface without absorbing it. This prevents the fabric from swelling, and keeps it lightweight and warm. The fabric is made water-repellent by treating its outer surface, however this property may deteriorate with use. We recommend that you restore it after each wash
PFC-free water-repellent treatment
With the MT100 padded jacket, the water-repellent treatment does not use PFC (perfluorocarbons) or is considered 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.
How to restore water-repellent properties?
Once you have cleaned your padded jacket, we recommend you use a water-repellent reactivator spray to preserve the hydrophobic properties of the outer fabric
A tear on a padded jacket can happen when trekking! The good news is that it can be repaired so the tear doesn’t get any bigger or to stop the synthetic fibres from escaping. Don't you feel at ease carrying out this repair yourself? Don't worry! Our in-store Decathlon workshops offer a repair service to mend your padded jacket using a heat-bonded patch.

A score for comparing products' environmental impact
The environmental impact of the product is calculated based on its entire life cycle and using different indicators. A general score from A to E is provided to help you easily identify the most eco-friendly products by comparing products of the same type (T-shirts, trousers, backpacks, etc). Decathlon is committed to displaying this environmental information. More information:

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.

Stockage tips
To keep the wadding inflated, we recommend you store your padded jacket on a hanger and not folded up in its pocket!
