The bag is really good! I use them for the university. But she has the perfect format. Inside it has one large compartment and one in which you can stow away blocks, stapler, etc.. Times should leak slightly, the documents are then also not the same way. It has a zipper, so that even in the rain nothing gets wet. The material has not passed even in heavy showers, no water. Front there is a zippered pocket and two more, then no bits and pieces in the bag is lost. On the other side is a compartment with snap closure, in which I always stow my Tablet. All in all it is very well made and exactly what I was looking for. In the color gray to fit pretty much everything.
