Needed a new backpack for the university, which is large enough a few books, a 1.5 liter bottle to store a file folder and other odds and ends. Large enough, he is disappointed in any case and the processing either. How good the quality really is is the daily show. Practically, the chest strap, if one times but have to walk longer distances. The laptop compartment could be a bit larger, it often happened to me that there inadvertently slip into my books when I without looking stuck in the backpack.
