- How warm is this padded jacket?This down 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 5km/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 wadding weighing 125 g/sqm in the body section 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 materialsThis polyamide canvas uses 20 denier threads (measurement unit of the thread) and resists up to 20,000 abrasion cycles. Durability is calculated using the Martindale test (Standard 12 947-2). This test is to rub the jacket’s material against another material to observe how the product resists wear. Outer: 100% polyamide fabric 39g/sqm, 20 denier Lining: 100% polyamide fabric 35 g/sqm, a mix of 15 and 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, but this property may deteriorate with use. We recommend that you restore it after each wash.
- How to restore the 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. This renews the fabric’s water repellent properties and optimises performance throughout the lifespan of your garment. You will find it in store and on our website by entering the reference 8817233.
- A snag? This is how to repair your down jacketA tear on a padded jacket can happen when trekking! The good news is that it can be repaired with a repair patch so the tear doesn’t get any bigger or synthetic fibres escape. Don't you feel at ease carrying out this repair yourself? Don't worry! Some Decathlon workshops offer an in-store repair service to mend your padded jacket using a heat-bonded patch.
- FunctionsInside flap under the zip that protects from the wind. Elasticated cuffs. Elasticated cuffs, Soft fabric flap at the top of the collar to protect the chin. Tightening with an elastic cord and toggle at the hem. Hood with elasticated bias binding.

Ecodesign approach

Using this finishing process enables us to reduce CO2 emissions linked to the production of undyed textiles by at least 53% compared to conventional dyeing.

Using this mass-dyeing process enables us to reduce CO2 emissions linked to the production of dyed textiles by at least 17% compared to conventional dyeing.

Using recycled polyester rather than conventional polyester reduces the CO2 emissions linked to the material by at least 17%.
