The bag is water proof, has a nice design and the blue interior fits very well to the outer style. The shoulder strap is adjustable, but unfortunately only with Klettverschlüssen.Innen the laptop compartment is well padded so can absolutely anything happen in minor knocks but should fall off the notebook still does not. Otherwise, the design description of the laptop bag is true and you have to be prepared for any color or material surprises.
I have looked in the hope that my 15.6 inch notebook bought fits this bag. With the specified dimensions I have previously measured my notebook and actually it should then fit into this bag. This does also, but just barely, as with so many laptop bags offered. (Is the boasted) So with a lot of page space is with me not so much.
