The best pants anywhere. A must have.

These pants are lightweight, but have proven to be tough. They are the most comfortable pants I've ever worn. The pocket system is ideal. With 4 zippered pockets on the front, I don't have to sit on my wallet. My wallet is secure in the zippered pocket in a place where I can see it. Pickpockets are stymied. Another pocket is perfect for my large mobile phone. The pants are quick drying for use when traveling. I bought my first of these pants for a specific purpose, but now they not only serve my outdoor adventures, they are my everyday pants. This is one of Decathlon's best products.

Mens forclaz mt500 EXCELLENT!!!

Some of the best outdoor pants I've ever owned, and for the price they absolutely cannot be beaten. Super comfortable and allow easy movement with the fabric stretch and good waist. I have three pairs of the same pants. I wish they came in more colors and I'd buy even more pairs!

Terrible quality

Any thinner and they'd not exist. Best part of £40 and the bag had better wind resistance. Instant return.

Brilliant for the price

Lightweight. Comfortable. Durable. Practical. Great value for money. And…….. this is a product that you can actually see in a physical Decathlon store - unlike many other products found online.

Will buy again

Too Big

These trousers are an update on those I've purchased before. There has been an increase in size of the ones I bought previously - longer leg and gusset. Much too big for my waist size.

New go-to!

Absolutely love these trousers! I have the equivalent Montane items, twice the price, and I actually prefer these Forclaz ones. Features and pocket position is great, fit is fantastic - more snug than others so no 'ballooning' in the wind! Used on a few treks now and quality seems brilliant.

Additional Product Information


Main fabric

  • 100% Polyamide


  • 12% Spandex
  • 88% Polyamide


  • 100% Polyester cationic
  • 85% Polyamide

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 1 zipped pocket at the right thigh with 1 smartphone compartment inside. 1 flap pocket on the left thigh 1 zipped back pocket Elastic tightening system at the bottom of the leg for a perfect fit of the pants on 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. For this, we recommend that you wear overpants such as the 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 33" in size M Width of pant hem: 8.4" in size M

Eco-design: what improvements have we made?

Not only does textile dyeing require a lot of water, but it also discharges waste water from the dye baths. To reduce our environmental impact, we used a mass pigmentation process called “dope dyeing” on the black pants. This process incorporates the color pigments from the initial thread manufacture to reduce water consumption. In this way, we can reduce the carbon emissions associated with the manufacturing of the pants by 30%

Determining the environmental impact of our products

The environmental impact of the product is calculated based on its entire lifecycle 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, pants, backpacks, etc.). Decathlon is committed to displaying this environmental information. For more info:



Product testing

These pants have been field-tested in real conditions. They were worn for 5 weeks by several testers independent from Decathlon who undertook the Grande Traversée des Alpes (GTA) in late spring 2017.
