The Lithium 30 backpack is made mainly of recycled materials with a water-repellent finish, without PFC content. Comfort is provided by a softly padded waist belt and highly breathable EVA foam shoulder straps. If you do not need a waist belt, you can simply remove it. The same goes for the integrated backpack raincoat. Air vents between the back system made of 3D EVA foam guarantee good ventilation. It has an adjustable back length and a U-frame for proper weight distribution, which provides high comfort and unlimited movement when worn. The backpack is equipped with side compression straps, loops for trekking poles and is compatible with the hydration system. Lithium 30 has 2 mesh side pockets that are accessible even when walking, a large stretch front pocket, a front zip pocket and a flap with an outer and inner pocket with a key pocket. You will definitely appreciate the pockets on the waist belt, one with a zipper and the other with a folding one - ideal for a mobile phone.
