The North Face engineered their Routeset Trousers with flexibility, adjustability and movement in mind. The constructed waist provides a solid fit and low bulk under a harness. In addition, the inseam gusset and low-profile friction locks at the leg openings accommodate a range of mountaineering boots. Add a touch of stretch and articulated, double-layer knee panels, and you'll be able to move unrestricted on technical climbs. On top of that, they're made from soft yet tough organic cotton, making them a kinder choice for nature.
