This backpack looks small from the outside but it easily fits my 15.6 " laptop, ipad, 2" 3 ring binder, mouse, pens pencils and still has some room. It is lightweight and professional looking. I really like all of the pockets and storage options. I've only had it a couple of weeks so I am anxious to see how the fabric holds up. The fabric looks nice, more like a business suit rather than the plastic looking backpacks.
