I was fit in looking for a backpack that I can take on board with Ryanair (next to a trolley) and in my tablet, my keyboard, a book, purse, headphones and snacks. After my first impression it was an impossibility that to get everything in this small backpack. But surprise: it fits in everything and a small bottle of water would have even still square. I love this backpack. It is light, easy to carry around and I got all this for my correspondence course. Those looking for a small backpack, the tablets or DinA5 folder to easily create, which I can only recommend this backpack. Especially handy I find also the key hook, to which one can attach his key ring. No more annoying search for a key!
