When you go hiking, you like a challenge. Your backpack needs to pack in quite a bit. The Lithium 40 is made mainly from recycled materials and the durable water-repellent treatment is PFC-free. The back length can be adapted to suit your needs. Anatomically shaped, softly padded hip belt and shoulder straps provide additional comfort. If you dont need the hip belt, you can simply remove it. The same applies to the integrated rain cover and the bottom compartment with external access. There are secure attachments for trekking poles and an ice axe. You can also use the compression straps to carry equipment. The Lithium 40 is compatible with hydration systems and the mesh side pockets allow access even when walking. A flexible and spacious companion for demanding tours.   Detachable, padded hip belt Height-adjustable flap with internal and external pockets Comfortable thanks to the anatomically shaped, soft padded hip belt and shoulder straps Large stretch front pocket Forward-pull hip
