Technically advanced trekking trousers with optimized fit. Intended for alpine trekking where mobility and durability are imperative. The seat and knees are pre-shaped and have extra strong seams. The Keb Trousers also have durable G-1000® Eco at the seat, the front of the legs, knees and on the inside bottom of the legs, with double layer fabric for reinforcement against wear from hiking boots. A zippered ventilation opening from knee to hip and along the calf releases excess heat. The trouser fly is also extended to enable extra ventilation. Two leg pockets, one zippered and the other with a flap and inner mesh pocket for small items. High hand pockets hold their contents even when sitting down. Strap adjustment with buckle on the cuffs and boot hooks to attach to ski or hiking boots.
