Colour nothing like advertised

Nice pair of trousers but the colour is nothing like the websites photo. Hardly any difference in the patches to the trouser which was disappointing as this was the reason for purchasing this style. It has been mentioned several times in reviews and yet the photo has clearly not been updated!

Very good trousers but need a bigger size

Trousers feel lightweight and have the option for unzipping into shorts. Only issue is size. The 32 medium is good for length however are tight around the crotch meaning they’re not comfortable when crouching down of lifting knee up. I’d say go up a size. Hopefully I can exchange these to a bigger size as they do seem very good!

Good but not for me

I would buy them as any Emergency to keep you going but just not as good as the 500, but would do the job

Great trousers

Often when I buy "leisure" trousers, they are too baggy for me, even if the waist is the corect size, but these are a perfect fit. There is enough room for movement, but not at the expense of looking like you're wearing a sack. Definitely a good buy for the price.

No color distinction. Very thin fabric !

Color of the water proof patches should be more dark or black. It looks like single colored trouser. Waterproof patches are not visible especially in pictures. Please make it proper dual colored trouser. Also the fabric is very thin, it's good for summer though. Quality is definitely good. Trouser was too lengthy, I had to go to tailor to alter it and I'm not happy with color.

Additional Product Information


Main fabric

  • 100% Polyamide


  • 100% Polyamide


  • 100% Polyester cationic


For the main fabric, we decided to use a more environmentally friendly dyeing process Fabric dyeing uses a lot of water and also produces waste water from the dyeing baths. To reduce the environmental impact, we chose a dope dyeing process that integrates color pigments during the yarn manufacturing. We reduce CO2 emissions by 30% compared to the former model.


To guarantee unfailing durability, on the knees and buttocks, we use light fabric (5.3 oz/sqm) that is very durable, made from 200 denier polyamide yarn (on the warp) and 320 deniers (on the weft). Indestructable!!

Water-repellent properties info

These pants have water-repellent inserts (knees, buttocks) that enable the water to slide off the surface of the fabric. Please note that 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 over-pants such as the Trek 500 (ref. 8493660). Water-repellency can be reactivated by tumble drying the pants for 10 min on low temperature.


To make it easy to identify the bottom of the legs, we have used a red zipper pull on the right leg and gray on the left. You will not mix them up!! Partially elasticated ankles to better fit your backpacking shoes!

Sizing info

Sports cut that offers good freedom of movement. 31.1" pants inside leg in size 36 (L) 9.4" shorts inside leg in size 36 (L)


We recommend that you always wash the pants with the bottom of the legs zipped to ensure that the color washes out evenly!



Product testing

These pants have been tested and validated in the field in real conditions. It was worn for 5 weeks in spring 2019 by several people who went backpacking in the Canary Islands for 2 weeks, followed by 3 weeks on the GR10 route in the Pyrenees.
