When you go hiking, do it right. Your backpack needs to be able to pack a lot. The Lithium 40 is primarily made from recycled materials, and its permanently water-repellent coating is PFC-free. You can adjust the back length to suit your needs. Anatomically shaped, softly padded hip and shoulder straps provide additional carrying comfort. If you don't need the hip belt, you can simply remove it. The same goes for the integrated rain cover and the externally accessible bottom compartment. Trekking poles and ice axes can be securely attached. The compression straps can also be used to hold gear in place. The Lithium 40 is compatible with hydration systems, and you can easily access the side mesh pockets while on the move. A flexible and spacious companion for demanding tours.
