I have long been looking for a bag, in which I also have a mobile printer and the associated cable / mouse a place for good next to the laptop. And in the then still a wide A4 folder and pen holder fit. Nevertheless, the bag should be easy to handle and have a little weight.
In this case I'm finally at the finish: handy, grows with the content. Lightweight, durable, weatherproof. And looks good. Unrestricted 5 stars for this panacea.
