I've had this for some time and like it more and more as time goes by. Yes, the interior is small but it will accommodate a glasses case, cosmetics purse, keys, cell phone, camera and a magazine or Kindle easily. If I were designing it, I'd dispense with the unusable interior options and simply add one or two decent sized interior pockets. The two external zipper compartments are excellent.
It looks great for a backpack and like all Bagallini bags, it's durable and easy to clean.
