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!

Great walking trousers

Very comfortable and pretty warm. I used these for the Test Way, where I got soaked. They stayed pretty dry under waterproof trousers and, although they got a bit damp, dried quickly. Useful pockets to store maps and phone. They worked very well for me!

Very comfy - Look good !

My main worry was what size to choose, after some post lock-down over-indulgences. For once these are perfect. I am 1m80 (5'11), a bit chubbier than I would like (90kg) at the moment. If I'd followed the sizing advice based on Waist dimensions, I should have gone for the size above, I thought this was way too big, so I decided to go for UK 39" / FR 48 and it is just perfect. They are comfortable, have a good stretch which would allow you to "grow" (in the wrong places), but also allow you to keep them with a smaller waist due to the elasticity (and the belt) ... So perfect ! Well made, comfy, light which is good, and look great for casual use, but also sturdy. A great product ! Little velcro with the button-clip to close the trousers, which I am not necessarily a fan of, but great overall ! Decent price for the quality at (£34.99).

Bought For Cyclocross / Gravel Riding

I originally bought these as an additional layer when riding in winter / spring forests. I found that cycling tights didn't keep me particularly warm, dry or comfortable. I took a bit of a risk with these but honestly love them. They're tight on the quads and ass, but seems as i'm built like a dump truck with a 32 waist this is expected. Saying that, because of the stitched panels and elastane inclusion, they passed the "squat test" with flying colours. They don't ride down your butt when riding (or squatting), have enough space for bib shorts underneath and are water repellent. The pockets are a little tight, but again I think this is a personal issue, not a product one. My only qualm is the lower leg is a smidge loose, and no, i don't have small calves. but this is to accommodate hiking boots rather than cycling cleats. I solved with this an elastic band to keep the trouser leg out of the chain. In these warmer months, i still find myself wearing them as they're particularly thick and add a layer of protection against stinging nettles, bushes and the odd cow. If you're not a fan of cycling leggings / tights and are looking for a lightweight, all purpose trouser, these are for you. Especially when a set of "gravel cycling specific" trousers will see you back £50+ and look like tarpaulin.

Good material but tight

The product itself is great - good design and made from seemingly quality materials. However, it came up very tight around my quads and glutes! The waist measurement for me was perfect so I'm disappointed there isn't more give around the seat area.

At last proper hiking trousers !!

Just received my Forclaz MT 500. Trousers . And what a joy to wear them . Lightweight.soft fabric . These are quality hiking trousers . You'd pay double the price for the well known hiking trousers . Save your money buy these you won't be disappointed.

MT500 trousers

I am very pleased with these trousers. Lightweight yet durable materials. Very comfortable and warm. Plenty of pockets for keeping things handy. Finally, good value for money.

Bit snug

I would say i am of average size, 6ft1 32 waist and 32 inseam. I got these trousers and they are well made. The only draw back to them is that they are a bit snug around my quads. I am unsure with how to rectify this issue but jusy so people are aware, if you are an average person these may come uo tight in certain areas.

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:

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.
