Good quality, hike under rain

Good quality, easy to put phone in pocket. Doesn't feel uncomfortable when hiking under light rain. Will get another one

Very nice!

First time I ordered these, I was sent the wrong size (30/31) and a (31/31) was what I originally ordered but still tried them on and i realized I needed like two sizes bigger. So I reordered them again for size (33/31) and they fit perfect. I am petite and have a short torso so the pants are high waisted on me which is what I was hoping for! I think these pants are so awesome. The material seems pretty strong compared to a pair of trail pants I got from REI. I was worried about the zipper part looking too bulky around the legs but they are fine. I really wish Decathlon would carry petite sizes because my only complaint is that they are pretty long on me so I am going to have to make some alterations but other than that they fit nicely around the hips and I love that they are a little stretchy.


Love the 2in one option

All dressed up with no place to go!

Very happy with my purchase, sadly had to cancel our trip due to Covid Lockdowns.

Brilliant product

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!!

Is this the most perfect hiking pant ever?

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!

Comfortable but there should be more/bigger pocket

These are comfortable and they're versatile for the weather as you can wear them as either shorts or trousers. However, the two non-zip pockets at the top are quite small. There is also only one zip up pocket on the right leg, and not the left. There should be a zip up pocket on the left leg as well, and all of the pockets should be larger. The men's equivalent of the product has 4 large pockets, so the women's one should as well - it only has 3 and they are not as big. These trousers are not tight fitting and could easily have more (and larger) pockets. For this reason I am hesitant to recommend this product to others, and I wish I had bought the men's one instead.

Love these

Super comfy and true to size.

Light & very quick drying

Very comfortable & practical. Zips on legs are colour coded to make it easier to attach correctly although I have worn mostly as shorts so far. Good pockets, nice length as both shorts & trousers (I'm 5'7"). Dry really quickly after a downpour or when washed.

Good value

Water-repellent properties information

These trousers have water repellent areas (shins, buttocks) that prevent water from entering the fabric. Please note, this does not mean WATERPROOF.The water repellent property prevents the trousers from getting wet too fast and slows down the water ingress but will not keep you dry under steady rain. To do this, we recommend to wear over-trousers, ref 8504646.Water repellence can be reactivated by tumble drying the trousers for 10 min on low temperature
