Various pockets are not left with a back pocket to put a laptop and several convenient storage inside the main pocket. The latter is also large enough for a sweater, light jacket see, and some small business. He also has something to attach a tripod bag (without one, I do not know if the system is as convenient as the rest).
In addition, the "raincoat" allows the bag to put it away if you experience heavy rainfall.
The different neck straps hold well and finish the bag looks ok. I did that for a month, but during that time I have had the opportunity to go twice with city trip, and it served me well.
The only downside is that the bag is relatively bulky. For use in city trip, sometimes you have to be careful in stores or transportation, it sometimes feels a bit like a bull in a china shop.
In short, very practical bag you can put her camera and a handful of goals, plus personal belongings. The straps allow to avoid having all the weight on his shoulders. In return, the bag takes a non-negligible volume.
