Technical information


We have chosen to use a more environmentally friendly dyeing process for the main fabric. Textile dyeing requires a lot of water, and also releases wastewater from the dye baths.To reduce this impact on the environment, we choose a process of dyeing in the mass, also called Dope Dyed, which integrates the colour pigments from the manufacturing of the yarn.
We therefore reduce CO2 emissions by 37% compared to the old model.


To ensure durability, we use a lightweight (150 g/m2) but very strong and durable fabric on the knees and buttocks.It is made from polyamide yarns of 200 denier on the warp and 320 denier on the weft (the denier measuring the thickness of the yarn).Indestructible!!

What is the water repellent feature of the component?

These trousers have water-repellent inserts (knees, buttocks) that let the water slide off the surface of the fabric. Please note, this does not mean WATERPROOF.
The water repellent property prevents the trousers from getting wet too fast but will not keep you dry under steady rain.To do this, you will need a pair of over-trousers like the MT500 model (ref.8493660).
The water-repellent properties can be restored by warming the trousers in a tumble dryer at low heat for 10 minutes


To make it easy to identify the leggings without hesitation, we have used a red zip puller on the right leg and grey on the left. So you won't confuse the two! Partially elasticated lower legs to fit your trekking boots better!
