The Mountain Active Pants mean business—when the only business on your agenda is on the mountain. These lightweight hiking pants were made for moving in the mountains, inside and out. Built with hard-wearing durability and a water-repellent finish, they can handle tussles with thick trees, jagged rocks, and unpredictable alpine weather. Meanwhile, soft, easy-moving stretch gives you the freedom and comfort you need for your most complex routes. With flex-friendly features like articulated knees and a gusseted crotch, boulder-friendly zippered pockets, and the addition of recycled stretch nylon, these high-climbing, quick-drying bottoms are just as trail-hungry as you are.
