Best backpack ever
It is the perfect size, very functional. Side compartments are flexible. The only thing is the roobar is in the wrong place. When it rains, your stuff (for me it was a book) can get really wet. I recommend pulling the zippers to the side in heavy rain. I ended up buying a rain protector for it. Sometimes you just wont have time to unlock and zipper it sideways. Really, in the rain you shouldn't have to choose between safety from people and safety from nature. Otherwise perfect.
