DS went through 2 zipper binders last year. The case it zipper binder lasted fairly well (except the small zipper busted-I sewed it back together). Is there some miraculous zipper binder that survives middle schoolers or can someone please invent one?

To add to it they will have chromebooks so I'm trying to decide where it will go-I see case it has a version with a second part for a laptop-has anyone tried it?
