I have a backpack for a few days now and am very satisfied with the backpack. The backpack has many pockets (esp. The lateral compartment on the back has to be mentioned, where you can easily plug in DIN A4 documents and can get out without the main tray to open) and plenty of space in the main compartment. The backpack is very light and the processing is very stable and I think that the backpack should last a few years.
Per - Many subjects * Two side pockets [eg a 1L Coke bottle fits in] * An upper compartment [enough for Sunglasses & Co] * Lateral compartment on the back of [greater than A4] * A front compartment [ca. A5]) - Sufficient space - Solid processed - Comfortable to wear - looks very good
