Trekking Trousers are a good buy.

Comfortable, easy to clean and lightweight. Yet tough, durable & water proof. Haven’t taken off since I bought them!!

These pants provide the wearer with all it promises. Comfort, style and wearability. They move with the person not restricting movement and they look sharp. They also have the useful gaiter length on the legs. A good pair of pants.

Excellent product

Very very satisfied customer. I wore it for 5 days continously during my Kuari Pass Trek and it went thru snow and water without any soaking of water and without any smell.

1 of the best products out there in Decathlon.!

I wore it for Chaddar trek in Leh, India where temperatures can drop down to -25 to -30 deg C and also gets windy and this trouser paired up with a Merino wool thermal kept my legs comfortable. The multiple pockets are very helpful and the slim fit makes you look good. I can't just pen down how helpful the zips close to the feet are, makes a world of a difference while changing socks and shoes..

Great trousers

Wore them in France in winter for walking. Comfortable and hard wearing.

Totally Satisfied

Very good in water repellening. Zipped pockets are very useful for carrying mobile and other documents. Have been using it for the last four months . I am very much satisfied but I hope the price should be a little lower.

A great choice for all weather

It’s a great choice for all weather conditions, water resistant is quite well, not recommended to hike through bushes as you may end up in some surface damage

Water-repellent properties info

NB 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-repellency can be reactivated by tumble drying the pants in the dryer for 10 min on low temperature. You can also use the FORCLAZ re-waterproofing spray (ref 8554908)

In the event of rain...

These pants are not waterproof. If it rains, we recommend you protect yourself with waterproof and breathable overpants. Check out the Trek 500 overpants (ref. 8493660).
