Product details:

Whether you're tackling an alpine climb or an ice climb, the Arc'teryx Sigma FL Pant keeps you moving fast and light in the mountains. By offering an ideal balance between weight and durability, the Sigma allows you to confidently maneuver technical routes. This is achieved through its material mapping construction. Arc'teryx placed Wee Burly Double Weave in the seat and knees for added durability while keeping the rest of the pant a lightweight and stretchy Fortius 1. 0 for mobility. Its slim fit and tapered legs further enhance freedom of movement and are also crampon friendly so you don't have to worry about snagging the pant as you climb.
