Technical Information

Why create a V2 (version 2) of our iconic MT500 trousers?
The MT500 trousers have been improved. The objective was initially to reduce the carbon footprint of the trousers (see details below). Then, we used your reviews to improve the functional features. Thanks for sharing! The changes made include the following: - switching of left and right pockets for better smartphone carrying - use of more durable COATS thread for assemblies - double stitching on the back of the crotch for better durability
ECO-DESIGN: what improvements have been made?
The dyeing of the components requires a lot of water and also produces waste water. To reduce this environmental impact, we used for the fabric of the reinforcements of our black trousers, a process of mass dyeing called "dope dyed" which integrates the colour pigments during the manufacture of the yarn and avoids dye baths. This process allows us to reduce the CO2 emissions of the trousers by 14%.
Hybrid structure
Trousers designed with 2 different components: - a durable fabric (207 g/m2) on the areas that need protection from abrasion (seat, bottom of the leg at the front). This fabric is also stretchy, enabling great freedom of movement. It has a water repellent treatment. - a light and breathable fabric (150 g/m2) on the rest of the trousers.
What is the water repellent feature of the component?
These trousers have water-repellent zones (lower leg and seat) that prevent water from getting inside 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 restore the water repellent property, put the trousers in the tumble dryer on low heat for 10 minutes. Otherwise, you need to add a pair of waterproof over-trousers (ref 8504646)
2 zipped hand pockets near the bottom 1 zipped pocket at the right thigh 1 pocket with a flap at the left thigh and 1 phone compartment Supplied with a belt.
Hand pocket opening direction
We have deliberately designed the sealing direction of the hand pockets as downwards. As such, the zip's slider does not irritate you when you tighten the waist belt of your backpack, and your things stay very safe in your pockets!
Which size should I choose?
Fitted cut and use of stretch fabric in the right areas guarantees high comfort levels when moving around. Choose your usual size. Inside leg 80.9 cm in size 40 (M). Hem width: 19.7 cm in size 10 (M).

Product test
These trousers have been tested and validated in the field in real conditions. They were worn for 5 weeks by several people who undertook the Grande Traversée des Alpes (GTA) in late spring 2017. The V2 (version 2) of the MT500 trousers, which includes the improvements made on the product, was tested during the summer of 2020 in the Northern Alps. These tests were used to validate the MT500 trousers in real-life use.
