Everything a backpack should do, this one does. The Boa squeeze ($130) has separate internal pockets for your laptop, tablet and notebooks; side pockets for pens, pencils and small devices; and front pockets for your headphones, phone, ID, wallet, keys, etc.
But two features really make the Boa squeeze special. First, it's waterproof -- so no more books ruined while you're standing at the bus stop getting drenched. And second, it has a light-colored interior, so if you're looking for some small object like a pen or an eraser, you don't have to scrounge around in the dark depths of your bag to find it.
It's thoughtful touches like that that put the Boa squeeze on our list.
