Too tight in the crotch

There’s no room for the boys in these pants. I’ve got chicken legs so the legs fit although they are very slim. The big problem is the crotch for men. It’s cut too short and tight, forcing the boys to hug one leg or the other. Bummer cause I bought two pairs, I guess my women friends will be getting some free hiking pants.

Fantastic Trousers

These are just great, very comfortable and lightweight but warm for cool evenings. I will be buying more of them as soon as they are available

Buy them

I have had one year of use in these pants. 25 washes or so, many KM's of hiking and dog walking, 100s of fish and several camp fires later... They still look brand new. Not the softest material while sitting, kneeling or canoeing, but the flex and comfort works well. A+ for value! And I'm a teacher!

hiking and wear

like them a lot! very comfy and breathable, also water resistant. Be careful when sizing as you may get it wrong, otherwise would highly recommend for outdoor wear.


A good pant for hiking, rock climbing and on glacier. Comfortable and abrasion resistant.

Nice pants

Overnight hike with these pants and can't say a bad thing!

Hi Marc-Antoine,

Thank you for the comment on the trek pants. We love to see that are clients enjoy are products. You have a 2 years garantie on them. So if ever something breaks on them before time of normal use, you can always return them and we will give you another pair.

Have a good day! :)


Nice material but tight on the thighs

Could use a bit of improving on fit

Walking trousers

A good fit. Lightweight and quick drying. There's a handy phone pocket within the right hand lower pocket. Would have liked a rear pocket - but that's just a personal preference, as I normally keep my wallet there.

Great trousers

Brilliant trousers, really comfy for long walks and treks. Allow lots of movement and dry quickly. Have worn many times and have lasted well. Have bought in another colour to rotate!

Comfortable and lightweight

For a summer walking trouser, these are brilliant. I like having multiple pockets and when washed properly with tech wash or equivalent product, they are really quite water repellent in showers. Great purchase.

My favourite trousers. Very comfortable and very quality

icon-circle-checkmark verified purchase

I have two pairs of these and use them for cycling and hill walking. One pair I have had 18 months and it is like new, so well made. Lots of good pockets, some with excellent zips. Flexible in all the right areas and showerproof and quick drying. Would definitely recommend!


Lightweight ==summery use

Additional Product Information


Main fabric

  • 100% Polyamide

Outer fabric

  • 88% Polyamide
  • 12% Spandex


  • 100% Polyester cationic


  • 85% Polyamide
  • 15% Spandex

Hybrid construction

Pants designed with 2 different components: - a durable fabric (7.3 oz/sqm) on areas that need protection from rubbing (buttocks, bottom of the leg at the front). This fabric is slightly stretchy, offering great freedom of movement - and a light and breathable fabric (4.4 oz/sqm) on the rest of the pants.

Water-repellent properties info

These pants have water-repellent inserts (bottom of the legs at the front, buttocks) that enable the water to slide off the surface of the fabric. Please note, this does not mean WATERPROOF. The water-repellent property prevents the pants from getting wet too fast but will not keep you dry under steady rain. For this, we recommend that you wear overpants such as the Trek 500 (ref. 8493660). Water-repellency can be reactivated by tumble drying the pants for 10 min on low temperature.


2 zipped hand pockets 1 zipped left thigh pocket 1 right thigh pocket with flap and 1 internal smartphone compartment. Elasticated tightening system at the bottom of the leg for perfect adjustment of the pants on the shoes. Pants sold with a belt

Sizing information

Straight cut that, thanks to the use of stretch fabric where it is needed, guarantees a high level of comfort when moving. Choose your usual size. Inside leg length of 33" in size 36 (L) Width at the bottom of the Pants: 8.4" in size 36 (L)
