Most comfortable trousers I’ve ever worn.

Light and sturdy

Great trousers they keep the wind away and maintain a comfortable temperature even in winter conditions! Also as with the whole trekking range from Decathlon extremely lightweight and comfortable.

Great spec, size up as snug

I looked around for the best walking trousers and these on spec and price were a match for more expensive known brands, some double in price. Sizing is key as they are close fitting. I went up a size, they have half size ups which help for that.

I received the product with mud and sweat marks on. Thank you Decathlon :)


Really love these trousers. Quite warm even in cold weather. The hook to attach to your laces and drawcord are handy features.

Everyone is different

I read the reviews before purchasing which were very good and I did take note of the sizing issues. Therefore, I opted for the size up (39”) as I am usually a 36” waist, I’m tall and slim but have an insulation pack to keep my food warm. I put the trousers on and without fastening the belt, they were round my ankles in no time ( which is not a bad thing if you are caught short in the field). So, off they went, back to the store, were I got a size 36” instead. Perfect fit, lovely and comfortable, very flexible, shape of the pockets I would say are ergonomically designed ( I know someone stated they had bother fitting their mobile in the pockets but are they sure they haven’t bought a tablet by mistake)? The colour of the pants in the picture does not look the same in the flesh as I would class them as military green but they are a nice looking pair of trousers and I am very happy with them. As usual, the customer service provided by Decathlon was excellent and I will continue to use them more and more.

" Excellent Value and Fit...! "

I have had these trousers for over a year. They are comfortable and are really a perform well outdoors. The materials are robust enough. I wear them for rambling and occasional mountain biking with my children. They are also very comfortable just to wear during the weekend, and great for camping. The only caution is that they are windproof but not waterproof, more water resistant. In my experienced they do dry quickly. It would be great if the also made a sand coloured version to add to the ones currently offered.
