I am a teacher, and you know teachers need to carry books and many other things. I like this bag so much , by the way is the second that i buy, the first one was a blue one, i like it so much because it has many departments, many pockets inside, divisions, where i put my personal stuff such as klenex, and on another space i carry my ipad, and on otherone i put my notebook and so on...i also carry my bottle of water.
