The Fjallraven Keb Trousers are technically advanced trekking trousers with optimised fit and carefully planned details. Intended for alpine trekking that requires climbing where mobility is just as important as durability and protection from sharp stones, etc. The rear and knees are pre shaped and have extra strong seams for this reason. And that is also why the trousers have durable G 1000 Eco on the rear, front of the legs, the knees and on the inside bottom of the legs, which is also reinforced with a double layer of fabric to withstand wear from hiking boots. The seam on the inside of the thigh has been moved and replaced by a connecting fabric panel to reduce the risk of chafing and wear. A zippered ventilation opening from knee to hip and along the calf releases excess heat. Two leg pockets with pocket cover flap, one with a zip and one with a mesh pocket inside for bits and bobs. High hand pockets hold their contents even when sitting down. Strap adjustment with button fastening at trouser end plus hook to secure to ski boot or hiking boot.
