I have an office at school, but I rarely have time to be there. I work with many students for short periods of time in their classrooms or just outside their classrooms, so I need to carry my materials with me. I have a leather zip-around portfolio from Staples that has done the job for me, but it is not big enough.

I am looking for recommendations for zip around portfolios, with a 2" 3-ring binder inside them and a handle of some sort (pull-out handles or a handles along the spine). Other features are negotiable. Leather would be preferred, but I am open to all suggestions, regardless of cost. I was lured by the soft leather of the one I currently have, but the drawback is that the handle has stretched the holder far enough that the metal tabs that kept it in place keep pulling through the opening.

I have looked at Staples (nothing) and have browsed Amazon, but they commonly do not tell what size the binder inside is (which seems like a rather important feature, IMO). But many of you are professionals or know of other, smaller shops or online places to look that I wanted to ask you all before making any decisions. Thanks in advance for your help!

Oh, and I would be open to other suggestions, too, for something to carry my things in. Perhaps there is something other than a binder that could adequately hold everything I need? Regardless, I am open to almost anything at this point!
