This bag I made last weekend. Weather outside was terrifying, hard rain that didn't want to stop once started. Many areas got flooded, horrible scenes not far from here. Some people lost all their belongings to the flood.
Back to the bag: The bottom is leather, also the side ring holders? On the inside there is some leather as well to support the magnetic lock which closes the bag. Also there is a little insert pocket to let your keys and phone slip in quickly.
