I bought a backpack for hiking and geocaching and was not erttäuscht.Wichtig were my many subjects. In the big coming in general equipment and supplies. In the private things like the key medium ect. In the geocaching front stuff. up front the small still remains free. On the side replacement batteries come in. So I know exactly where everything is, even in Dunkelen. So I do not have to search the whole backpack when I need something. The straps are well padded and can be there at the belt even Karabiener hook (eg for GPS or camera). The Antischwitzsystem works well. Yesterday I walked 7.5 hours and it was pleasant. Was sweating ego but more from the slopes than of the backpack. The top handle is also very solid and reflects. I am fully satisfied on.
