The main reason I suggested the Jet Set zip top tote is because it has a zip top. Both the e/w Hamilton and Sutton have open tops. Even stashing the bag away in your classroom, I would be concerned with an open top bag being left unattended, especially when you have your tablet with you. I would also be concerned with some of your child's smaller things falling out when using it on the weekend. The Sutton does mitigate this a bit with its separate zipper sections, but it still has a large open center section where most of your things will be placed. Have you considered the Selma?
