I agree with my predecessors and confirm a super quality of this backpack. Feast resistant material and good padding (feels good) you can conveniently carry a 15.4-inch notebook and educational material for example is enough space for a folder. Tip for the side pocket: 1 1/2 liter PET bottle can carry good because this can be fixed. Kluge purchase decision, who has taken such a high-quality and low-cost backpack.
