About the quality of this backpack has been written enough. I just wonder who is concerned about the structure of a camera backpack. If high-end cameras do not like one, to be doused with liquids. Therefore, the camera should always be above * * the beverage container because liquids usually obey gravity and flow down. Okay, beverage bottles could indeed be attached to the side. This would be with ribbons, a network or, as in normal backpacks already seen a zipper compartment quite possible. All this would be quite useful, as the beverage bottle is always transported upright. Only in this backpack it is transported * lying *. Since leakage is practically inevitable. By the way, I find it quite unpleasant, to secure the bottle using carabiner on the backpack, because the swings disturb when photographing. The Camera I gather mostly at the beginning of the photo session and pack them away afterwards. During the session, I would like to quickly and safely change my lenses, preferably blind. As a fixation with rubber bands or a click-holder for the lens cap would make sense. Because there are often situations where you want to reluctantly leave the rucksack and yet both hands should remain free for the lens exchange.
My suggestion to the manufacturer: - Drinks down or sideways - Camera well protected in the middle - Lenses easily accessible top - Clicks or rubber band mount for lens cap
