As I unpacked the bag, I was amazed at how big it is, although the mass were given. One should not underestimate the degree and if you do not need to buy a smaller bag. I, however, purely pack also besides school supplies, sports and motorcycling equipment, it is ideal for me. 2 bags for shoes and water bottle and very spacious compartment in the middle are ideal, missing tuhen most small compartments for small items. The only serious Disadvantages: The belt squeals. because the man is capable of repeated stimuli hide, you'll scare most people around you. The reason of Squeak is the plastic connector. Conclusion: for the price is the bag Well, it's worth it to buy them.
