I have a large cycling
I have a large cycling backpack manufactured by another company, and while I love that bag, I found myself wanting something smaller for my commute to grad school and other quick errands. Enter the Kadet! It's perfect for my needs. It holds my iPad Air (5th Gen) with a keyboard case, my 5x8 notebook, my reading glasses, and a pencil/pen case, all with room for other essential gadgets (even a spare tube!). Some folks want more pockets in the bag, but that would take away from the space inside and make the bag bulkier. Just get a small case or folio to hold any small essentials together.
