The size of this backpack is ideal: it fits a standard school binder and still has a lot of room for a lunch bag and other essentials. Love big pockets as well. What surprised me in a bad way - the fabric is very, very thin, almost...flimsy. Feels cheap.

This backpack is an upgrade from "Dora's bags are for babies!!!" and I must say that Dora was very sturdy compared to this one. We shall see.

Upd 12/30/12: I did survive a year and still looks pretty decent.
