Do you like to shift up a gear when hiking? Then you need lightweight and compact equipment. The Lithium 15 is the smallest member of the tried-and-tested and well-equipped rucksack family. It is made mainly from recycled materials and the permanently water-repellent waterproofing 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. The side mesh pockets are also easily accessible while walking.
