Ecodesign:We only dye every other thread, to reduce the environmental impact A new improved version of the Steppe 100 trousers thanks to your comments: Inspired by your feedback, we strive to improve our products season after season. For this model, we used a cotton/polyester fabric that is even more than the previous version (which was made of 100% cotton). Based on your feedback, our teams also added a zip-fastening side pocket, so you can now carry your keys, wallet and other accessories more securely. Free to move, stress free! To make sure you enjoy optimum freedom of movement with these trousers, our designers decided to use the fabric scraps generated during product assembly to create a reinforced crotch piece. As a result, you can bend down, step over obstacles and walk freely, with fewer constraints and less potential discomfort.
