I got this bag for my son for daycare.  Every day we have to bring clothes, lunch, blanket, etc.  This bag holds it all.  He is only 1 years old so of course for now I still have to carry it.  He's too small but probably next year it will be a better size for him.  It is easy to wipe out and keep clean (his lunch spilled once) which is a big plus for me.

I picked it because it doesn't have characters on it.  He's too small to like a certain character that much anyway and if I picked one he does like he'd grow out of that character by next year and not like the bag anymore.
