Love this bag and have bought it twice now This bag is adorable and very well made, not at all flimsy. Size wise I would say it fits two large bathroom towels if you rolled them up and stacked them one on top of the other. I bought the girl version first and use it to take my daughter's things to daycare as well as overnight visits to her grandparents. I just bought this blue airplane one for my 2yr old nephew with the same purposes in mind. It's list price is overpriced (in my opinion) so I would wait for sale, and get it for under 30.
