Product Customer Reviews

Hiking through rough terrain with no tracks and lots of blackberry,full length pants worked well and suffered no damage ,did not try as shorts yet. Pockets were very handy .
Light Weight, Durable, no colour fade, great value for money
Sizing small had to return swap size
These pants are too complicated and have too many pockets. Decathlon's MH150 are much better and lighter.
Purchased these in France 2 years ago. Fantastic travel pants for 2 months across Europe. Very well made. Great as shorts or long pants.
Waterproof
Very frustrating that Decathlon couldn't care less for anyone with longer than 34 inch inside leg. Nothing you make fits me length wise and I am only 6 foot 2 which is really not so tall. These are annoyingly too short, the same as all your other trousers. Why not make 36 inside leg like other companies, it really is insulting.
These are very comfortable. Dry fast after rain. Light weight. However when ordering online I could not see how I could choose leg length. Being slightly shorter means I need a short leg length. A lot of overhang at the ankles isn’t a major issue but the right length would be better.
Bought for Fishing. Great to have them as short too
Great for work and play , dry quick , little bit of stretch , ample pockets , hard wearing , great value for money : )
As my job entitles for me to be outside for a long period in any weather ( hot or cold) i can rely on these and from many of my customers have had only compliments on how good and professional they look.
Comfortable and well made. Good value.
Nice and light to wear
Very baggy in the legs
As described
