Product Customer Reviews

I was dubious about buying pants online, but these fit perfectly!! They’re so comfortable. I’ve done one hike in them which included a lot of scrambling, there was plenty of room to move. A couple of river crossings, but they dried in no time. Will be ordering a couple more pairs I think!!
Forclaz Travel 100 trousers are my absolute favourite of the 10 or so hiking pants I have from various brands, including other hiking pants from Decathlon. They fit well and move in all the right places even during the most ridiculous hard-core bush-whacking. They seem indestructible - whether sliding down granite boulders or pushing through thorny undergrowth. They are warm enough for near freezing temps and yet cool on a hot Aussie day and dry almost instantly. Amazing product for the price! Thank you, Decathlon!
Loose and relaxed trouser when you are trekking.
Went trekking in these and when we came back, simple unzip the lower detachable part and you are in your comfy shorts. I just loved the functionality of this

Additional Product Information
Composition
Main fabric
- 100% Polyamide
Yoke
- 6% Spandex
- 94% Polyamide
- 100% Polyester cationic
Eco-design
We have chosen to use a more eco-friendly dyeing process for the main fabric Dyeing fabric requires lots of water but also gets rid of waste water from the dyeing baths. To reduce this environmental impact, we have chosen a mass-dyeing process (also called Dope Dye), integrating the color pigments from the thread's manufacture. As such, we reduce the CO2 emissions by 15% compared to the old model.
Water-repellent properties information
These pants have water-repellent areas (shins, seat) that prevent water from entering the fabric. Please note that this does not mean WATERPROOF. The water-repellent property slows down water ingress and prevents the pants from getting wet too fast but will not keep you dry under steady rain. To do this, we recommend to wear overpants, ref 8504646. Water-repellency can be reactivated by tumble drying the pants for 10 min on low temperature
Sizing information
Uses a stretchable fabric on the seat and knees guaranteeing a high level of comfort in terms of movement and adaptability to different body shapes. Choose your usual size. Pants inside leg length of 31.9" in size 10 Shorts inside leg length of 7.9" in size 10
Hybrid composition for greater durability
On the seat and knees, the combination of a durable and stretchy fabric that prevents tearing (5.5 oz/m²) facilitates movement. On other parts of the pants, the resistant fabric is lightweight and breathable (4.6 oz/m²).
