When Fall semester starts, I'm gonna use my BV and trenino!! The trenino is very roomy and a little smaller than you think it is. A campeggio looks good too!! But I dont have one.. so I cant really say.. but the other tPFers are saying that its good!!
I think a campeggio would be good for binders and notebooks, but I don't know if textbooks are little too heavy. Maybe see if you know anyone who has some and try them out? Worse comes to worse, you can always buy a couple of bags, test them at home, then return the ones you don't want to keep.
I think Bubblesung said she used the cucciolo for school. It can COMFORTABLEY fit a laptop and I'm sure it has tons of room leftover (considering it is bigger than the campeggio and mine has some room leftover after I put my laptop in there with it's sleeve).
