The backpack is perfect for my 13 inch notebook and provides the perfect protection against shocks and other effects. The processing leaves nothing to be desired and the design is great too. Since I use the backpack for the vocational school I have been looking for something with which one can carry his school stuff .. As it is with me only a small Leitz folder, is also found in the backpack for plenty of storage space. Case, calculators etc find their place in the useful bag in the front area ..
