Finally a photo backpack with ventilation. I had now moved him five weeks in use and am with him about 150 km, of rain and 10 degrees to the sun and in the shade 32Grad ('m wandering in the sun). He wore himself fine, no matter whether loaded or empty almost brimming + full canteen on the side. Well, that one can so easily take out the laptop compartment and thus also longer objects can accommodate in the backpack.
The only thing that bothers me, that you can not accommodate DSLR + BG therein.
