This bag is lovely and looks very expensive, but beware - it is very deep and thus, eats contents. There is a zippered pouch in the middle to help organize your things, but between all of the pockets and pouches you can go mad looking for things.The strap is canvas with leather stiched in the center for support. I would rate this bag a 5 if the shoulder straps were entirely leather.One more note, the bag has a shiny finish and can be challenging with some casual outfits. I'm hoping the shine will wear down a bit the more I use it. That is if I can find my keys in it to go any where....
