I ordered this because I'm going to Europe and will be walking a lot and taking public transport.  I wanted it to be as theft proof as possible and light.  It is both.  Very light and just the right size and shape.  It fits my iPad and my kindle perfectly leaving lots of room for wallet, makeup and all the other things I need to carry when I travel on the plane including a place for a cell phone and water bottle.  It even has a little flash light so that you can find things in the bag in the dark.  There are lots of inside pockets and zippered compartments, locking mechanisms on the outside zippers and it has an adjustable shoulder strap.  Much more than I expected.
