I wish my work issued backpacks like this instead of laptop satchels.
The bag is really comfortable and durable, I have been using it for riding to tech on a motorbike and it's held up flawlessly. It carries everything I need (laptop, couple schoolbooks, notes, lunch, mouse).
There are a couple minor flaws. First, the straps on the front to cinch down the bag attach with this hooked metal buckle, and they just fall out all the time. Second, the top compartment's zip is one-sided and folded over, so it's hard to get stuff in there. Third, there's a heap of extra mesh zip compartments inside which to be honest are pretty useless, and could do with being reduced in number for simplicity and to save some space.
Other than that, fantastic bag.
