Hello Tim, thanks for your 5-star review. We hope you're enjoying!


Versatile trousers. Very good. Does need something on the bottom of the leg zips to keep them shut. Otherwise really good. Decathlon note the need for a mod. then they would be 5 stars.

Ok hiking pants

I have two pair of these trousers in different colors, but have the same issue, they snag on branches and the fabric pulls and shows weave damage in the front groin area. The fabric does not hold up well in my opinion. They do dry very fast which is helpful.

Pretty good summer walking trousers

Lightweight and quick drying. They convert very easily to become shorts, although not sure how long the zips will last, and unzip along the side of your legs so you can take them off without removing shoes. I’ve used them on a few (very hot) stages of the South Downs Way, and they performed well. Useful pockets and a good length.

Great trousers, a bit thin though

I found the trousers really comfortable and stretchy. The fabric feels really nice on the body. However, it's a bit thin so I don' t think it's a universal pair of trousers for cold and warm weather. Also, it's a bit disappointing that it has SOME parts water repellant and some parts not. What's the point. If it rains, even if it's lightly, I'll still get wet. Still overall, pretty nice trousers. Let's see how long they last :)

Really easy to unzip the legs to turn into shorts, even with boots on.

Excellent trousers. But watch the sizing - a mare!

Love these trousers. Bought a second pair - but sizing seems to have completely changed - and same size doesnt fit. Hard wearing - but got bleach on the knee and its taken the colour out.

Excellent trousers

Great trousers for walking, lightweight and with plenty of pocket space. Fit is pretty accurate and the lower portions zip/unzip easily.

The trouser is very good in terms of quality and comfort. I used it extensively during my trek in Himalayas in September which served as my go-to trouser due to its 2-in-1 modular feature and quick dry ability due to rainy season. The only concern for removing 1 star from Durability is that the waist-belt provided with this trouser broke during my trek, so I would recommend Decathlon to provide a better quality belt or suggest to buy a separate back-up belt from Decathlon. All in all, a very good product to buy.

Additional Product Information


Main fabric

  • 12% Spandex
  • 88% Polyamide


  • 100% Polyester cationic

How is the dark gray model eco-designed?

For the dark gray color, we used a mass pigmentation process called “dope dyeing.” This process incorporates the color pigments from the initial thread manufacture to reduce water consumption. This helps us to reduce 26.8% of CO2 emissions. More information:

Hybrid structure

Pants designed with 2 different components: - a durable fabric (7.3 oz/m²) on areas that need protection from rubbing (seat, bottom of the leg at the front). This fabric is slightly stretchy, offering great freedom of movement - and a light and breathable fabric (4.4 oz/m²) on the rest of the pants.


2 zipped hand pockets 2 zipped thigh pockets (and 1 mesh patch pocket on the inside of the right pocket) 1 zipped pocket at the back Elastic tightening system at the ankle for a perfect fit of the pants over the boot. Pants sold with a belt

What is the water-repellent property of the component?

These pants have water-repellent inserts (front of ankle, seat) that let the water slide off the fabric's surface. Please note that this does not mean waterproof. The water-repellent property prevents the pants from getting wet too fast but will not keep you dry under steady rain. To do this, we suggest adding outer pants such as model MT500 (ref. 8493660). Water-repellent properties can be reactivated by tumble drying the pants for 10 minutes on low temperature.

Sizing information

Regular cut and use of stretch fabric in the right areas guarantees high comfort levels when moving around. Choose your usual size. Inside leg of pants: 32.8" in size M Shorts inside leg: 10.8" in size M Width of pant hem: 8.4" in size M Width of shorts hem: 10.4" in size M

What about maintenance?

We recommend that you always wash the pants with the bottom of the legs zipped up to make sure that the color washes out evenly!
