A hidden gem. With every penny!

I was a little concerned about how good this jacket could be at such a low price point. I tested the jacket on an overnight backpacking trip with temps down to the low 40’s. I was warm and comfortable. The jackets isn’t real thick but I couldn’t feel the wind come through it. I was impressed. I would’ve gladly paid $80.00 for this jacket. It’s definitely worth it. If your getting backpacking gear together and trying to stay on budget then you’ve found your jacket. Seriously! Oh and it folds into its left pocket. Which I used as a pillow.

Great Value

I normally wear a medium to large jacket (size 40 USA). Ordered a medium when I read the sleeves are long. Fits a little tight all the way around--would not be able to wear fleece under it. Not many extras on this but the overall quality is excellent. I recommend it. Wore it in the Black Hills down to 30 degrees wind chill. Below that you would need a shell over it. Long sleeves are nice to put over your hands!

Pocket and waist

Pocket is get caught in the zipper. Really frustrating to fight with the zipper every time I want to use my pockets. 2nd is the waist is a little tight for a medium. It has a draw cord which is great but does starts off too small.

Slim Fit And Nice Materials

I am 6'2" and slim build w/ 32" waist. The Medium is a comfortable but snug fit with a single base layer. Even so, the arms are plenty long, it sits quite low on the waist, and has a generous neck up top. It's like a Medium chest with Large everything else. For me it's perfect.

Great light insulation

Great little jacket to throw under a shell when it gets colder. Very light and comfy

Lightweight yet insulating

This is one of the best buys from Decathlon especially during the black Friday sale.... hiking was wonderful with it!

Big or correct size

Been using Decathlon for years as I regularly go to Europe. I have learnt one thing. The sizing is European! Ie. Not good for British body shapes. The trousers and shorts never fit. The tops and jackets always have to be sized up. Until now. It would seem that if you are UK XL. Then buy UK XL. Alas sadly I had already removed the labels. Jacket wise I got it to wear under my motorbike jacket as the stock layering is always poor without exception. I could not wear my exisiting Rab as it has a hood. I do adventure tours so do not want to duplicate kit. One coat. Day and evening then (part of) pillow at night. For £27 this is a total bargain. And I have thrashed and trashed it this month. Only issue. The inner seems to come out of the cuffs when you put it on.

Sizes are not accurate

This does not look like the picture, I purchased a large and in comparison to other coats I have bought I would class it as a small. Tight round the arms, chest and belly as well as short fit. Very thin, very poor quality. Completely out of proportion. Will be returning at my own expense!

Good product for price

This is warm enough and can be warm with or without layers underneath meaning it's versitile for a number of weather temperatures. Not sexeist looking jacket but no issues at these prices.

Additional Product Information


Main fabric

  • 100% Polyamide

Main lining

  • 100% Polyamide


  • 100% Polyester cationic

Check out the eco-design of this padded jacket!

The filling of this padded jacket is made from 70% recycled polyester fibers. For the lining, we use a “bi-ton” dyeing process where only 1 thread in every 2 is dyed. This dyed thread is also the result of dope dyeing, which incorporates the color 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

On the Trek 100 black and Trek 100 blue models, the outer fabric uses a clean process known as dope dyeing (the thread is dyed before the yarn is woven) reducing 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 23°F during a standardized test in a thermal chamber. The model is wearing a synthetic long sleeve T-shirt and a light fleece underneath. It works with a simulated 3 mph wind. We have also tested this model in "static" mode; the comfort temperature is 41°F in this case.

Want to know more about the fill?

We use 100% polyester padding (70% recycled). The fill is made from silicone-coated spiral fibers that make it highly compressible and highly durable. Despite its low thickness, the air trapped inside provides high insulation properties while allowing it to remain 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 1.4 oz/m², 20 denier Lining: 100% polyester fabric 1.2 oz/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

Pfc-free water-repellent treatment

On the Trek 100 padded jacket, the water-repellent treatment doesn't contain PFCs (perfluorocarbons), i.e. it 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.

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

How to repair your padded jacket

A tear on a padded jacket can happen when backpacking! The good news is that it can be repaired so the tear doesn’t get any bigger or to stop the synthetic fibers from escaping. Don't 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.


Inside flap under the zipper that protects from the wind. Elasticated cuffs Flap at the top of the collar to protect the chin. Tightening with an elastic cord and toggle at the hem.

Determining the environmental impact of our products

The environmental impact of the product is calculated based on its entire lifecycle and using different indicators.

Decathlon is committed to displaying this environmental information. More information:



Product testing

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

Storage instructions

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