Functionally the adapter 46 is really well thought out. Camera and other lenses be stowed sideways, which seems at first glance a little unusual, but proves to be a good solution, especially when you transform the backpack to (but bulky) bag. Whether left or right handed does not matter the camera compartments are present on both sides. Up to a fairly spacious, but not huge pocket for everything, food is example. Outside of this head compartment is another zipper compartment protected narrow to accommodate small accessories or smaller papers.
A 13-inch notebook compartment can be found behind another zipper on the back side, so you do not have to do without a laptop or a tablet. Particularly ingenious is the system to accommodate a tripod. Since nothing wobbles in case of fall. Not to be forgotten is also the almost obligatory rain cover, which is housed on the lower rear side and moored so that it is drawn from there through the backpack and can not be lost.
Minor details such as the ability to store excess lengths of the risers with Velcro straps so that nothing hangs out, round off the package. A total of five points, if you do not fail due to a regulation on hand baggage. Make Lieber previously clever or play it safe and leave the backpack at home when traveling by air.
