You like to shift up a gear when hiking. You need lightweight and compact equipment for this. The Lithium 20 is made mainly from recycled materials and the durable water-repellent finish is PFC-free. Thanks to the particularly lightweight and breathable shoulder padding, you can enjoy a high level of comfort. Air channels in the 3D EVA foam ensure good cooling on the back. The padded hip belt has a fold-out pocket for your smartphone. If you don't need it, simply remove it. You can do the same with the integrated rain cover. The backpack is compatible with hydration systems. You can also access the side mesh pockets while walking.
