need a better belt and buckle system

generally comfortable pants, however, the belt really need some work. it gets loose easily and the plastic buckle broke after 1 month's use.

Hiking pants

Great pants for travelling! Recommend that included belt is removed and one uses a slightly wider belt

Hi Peter,

Sports enthusiast, Decathlon Ottawa


Selected for mountaineering. They are great. Sizing is quite snug so it’s important to go at least one size up for a regular fit.

Hi Krikorian,

Thank you for the 5-star review on these pants! We are happy to hear that you were able to find a product that works well for many different uses!

Sizing ?????

I ordered this item online in store. It wasn't easy to figure out the correct size for gift giving. The online was sized one way & the inshore another. WHAT? Then theres the issue that everything seems small... I wear a small in most items but not at DETHALON. I wear a large inmost items then have to have everything hemmed at least 6" Frustrating to say the least..

Hi Marcia! Thank you for letting us know about your experience. As Decathlon is a global brand, we list the sizing universally in the most common standards. On our tags you'll find US, GB, AUS (and more)! If you hop on the website to order, you'll only have the option to order the sizing we use most commonly in that particular country. We've added sizing conversion charts to the end of each aisle (in store) to hopefully make this system a little less confusing! Please don't hesitate to ask a staff for help in discerning the clothing sizes on your next visit, we're always happy to assist!

Great hiking pants - a little slim though

These are great trousers for a fall or summer hike. Though they do fir on the small side so beware.

100% superb pair of Trousers !

2nd pair ordered (put on wight so went up a size) Well made, extremely comfortable, excellent pair of walking and hiking trousers I fully reccoment this product

Great trousers

So good I am after another pair. Had to go up one size as I have big thighs and they were a bit to tight. This meant they were to big in the waist but as they come with a belt it’s not a problem. So stretchy they are great for freedom of movement.

Great, but wish they came in different lengths

These are fantastic outdoor trousers for hill walking, scrambling and climbing. Light tough and easy to move in they compare well with top brands like Rab or Mammut. My only beef with them is that they come in only 1 leg length, which for shorties like me is a bit of an issue. Luckily, they have a draw cord at the ankle.

What is the water-repellent property of the component?

Please note, this product is not waterproof. The water-repellent property prevents the pants from getting wet too fast but will not keep you dry under steady rain. This can be achieved by wearing overpants.Water-repellent properties can be reactivated by tumble drying the pants for 10 minutes on low temperature.You can also use the Forclaz re-waterproofing spray (ref 8554908)

In case of rain...

These pants are not waterproof. In the event of rain, we recommend you protect yourself with waterproof and breathable overpants.Get these MT500 overpants (ref. 8493660).
