This bag is very functional, and what makes it even better, aesthetic enough (far Targus type of black bag, the bag goes even dressed elegantly). The four pockets bag: small front may contain computer accessories, rule contains a zippered pocket in which you can drag USB keys or other SD cards. The central advantage of the pocket flared down: you can put books, a toilet bag, even the bowl of noon. It is quite deep and wide; it also contains a separate fine compartment, in which a slide ipad or some A4 size paper. The third bag contains the computer that comes to rest on the back; thus being protected from the outside; I return a macbook pro 13 inch in its cover without difficulty. Finally there is a clever pocket on the lower back, where you can drag wallet and checkbook. Two empty side pockets retiennnent out a small bottle of water, or a large bunch of keys (which is hidden from view). Small flat (hence the 4 stars, I would have put 4 and a half stars if that was possible), the straps tend to slide on the shoulder, asking very precise adjustment. However, once done this setting, you can set the excess cable with two small Velcro tabs. Anyway, I'm happy with this purchase, which combines functionality with elegance, in a bag that can carry many things without turning into suitcase backpack overloaded.
