Their ergonomically much more useful backpack

This medium-sized backpack is ideal for day trips or city tours.
2 networks for each ¹ / ² to narrow 1-liter bottles or tots, one inside pocket, in fits and an A4 block, a second compartment with 2 small mesh pockets and a small Wühlfach on the outside make because the equipment.

The manufacturer of this backpack is my opinion, one of very few who pay attention to ergonomic design. Stiffness, S-shaped formed and padded on the sides of the rear wall provide good comfort and ventilation.
