very unstructured bag and when lightly filled it is difficult to maneuver and use as a messenger-type bag.  the swivels on either end of the bag are difficult to keep straight thus the bag tilts are weird angles.  the velcro closures to keep the front flap closed are really lame.  i used it for about a month and then upgraded to a patagonia bag and while about 3x the cost is a much better constructed and useful bag.
