Not recommended, not suitable for walking

Sold in the Hiking department and buy for walking. I am very disappointed with this product. - Of course I chose it in a hurry (just tried it on to check the size). - I expected to find at least 1 interior pocket, there are none. - The side pockets are useless, the slightest object with a little weight (like a phone, or a wallet) unbalances the garment and interferes when walking.

Very nice Jacket 👌

Additional Product Information


Main fabric: 100.0% Polyamide ; Main lining: 100.0% Polyamide ; Filling: 100.0% Polyester

Want to know more about the wadding?

We use 100% polyester wadding (100% recycled) weighing 125 g/m2. 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 uses 20 denier threads (measurement unit of the thread) and can withstand up to 20,000 abrasion cycles. Martindale test, Standard 12947-2.Outer: 100% polyamide fabric 39g/m2, 20 denierLining: 100% polyamide fabric 35 g/m2, 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.

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 its performance throughout the lifespan of your garment.

How to repair a gilet

A tear on a padded gilet can happen when trekking! The good news is that it can be repaired with a patch so the tear doesn’t get any bigger or to stop the synthetic fibres from getting out.Don't you feel at ease carrying out this repair yourself? Don't worry! Some of our in-store Decathlon workshops offer a repair service to mend your padded gilet using a heat-bonded patch.


Inside flap under the zip that protects from the wind. 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.

Storage instructions

In order to preserve all the padding's fill power, store your sleeveless jacket on a hanger rather than stuffing it in its pouch!
