When it comes to carrying around their things & stuff, modern men have many options. The basic backpack is big in casual Boulder, the man purse (or ‘murse’), i.e. the messenger bag is more a ‘New York thing’, and some daring gentleman go retro with the briefcase.

Thanks to the popularity of ‘Mad Men’, mid-century formality has returned. And while the suit, tie, fedora trio may be a bit much for your work environment, a vintage briefcase (available here) is just enough. Add a pair of retro-inspired Tom Ford sunglasses and keep everything else modern (great jeans and a button down).
