Hello guys, I've been lurking here for some time and keeping "radio silence" , but now it's time to start a new topic, and also to contribute. I read a couple of threads about wearing a backpack with a suit, however, I just can't find a proper answer, so I apologise for starting a new thread about an old problem. As you may anticipate, I am in a long pursuit of finding a "formal" backpack, which would go nice with a suit and in the business environment (e.g. meetings and situations where everyone else has a briefcase), although I know that the words "formal", "backpack", and "suit" don't go together in the same sentence. However, since I have problems with the back, and for practical reasons, I am forced to use a backpack for business, which requires careful examination of the possibilities. I already tried with a messenger bag but it's not practical as a backpack. Being in my age (mid 20s), I don't think it's that bad wearing a backpack with business attire, but I'd like an optimal solution, or at least the closest one. The backpack I am looking for should be black, fit a 13" laptop and the usual suspects (charger, papers, pens), and it should not be too big (about the same volume as a briefcase). The closest I've found is a Porsche design backpack (attached pictures) but apparently it's discontinued. I also tried at Samsonite, Swiss Gear, North face, and others, but no luck. Any ideas? As I am not residing in the US, please do not advise products which are available only in the US.
