System Backpack

What is the most efficient binder backpack system?

for high school ... something light

I just use a backpack Jansport plane with two bags and a binder with dividers inch, that almost does it for me. It also helps keep the folder back in the same way you do doesn't look big and bulky backpack, also do not have more to shoot real people under the straps as high as they can go, so do not look like nerds
