Bought this to use backpack-style when riding my motorcycle or electric bike to work - then to convert to "regular" briefcase once there. Has worked out great. I have the black one and no one at work (I work in hospitals) even mentioned it looked any different than a regular soft briefcase. Plenty of pockets – good material has worn well so far. Looking at web pics, thought I’d put a water bottle in one of the two side pockets, but they are really small - fits my PDA or headset well – but only a small 8oz water bottle. However, plenty of room inside for a 1L water bottle, lunch, documents and lots more. Idea looked great and price was good so gave it a try – would definitely buy another one.
