My son is always complaining that he doesn't have enough bags for when we travel. I got this one, figuring that he could put various patches all over it so it would definitely be his and also so that he would have another bag for when he was packing things. I guess I didn't really look at the size when I ordered because it is bigger than a standard bookbag. This is actually really great because with any luck, he can use this one and leave one of the other ones at home. He should definitely be able to fit everything for a small overnight trip in just this one bag and have room to spare. At least, that's my hope for once the patches are on it and he is ready to start using it.
