Badass Longcoat: Ah, yes, the traditional garb of the adventuring classes, not to mention the more… rakish of the free traders. Whether it’s a duster or a greatcoat, it looks cool, contains plenty of Hammerspace even without exotic technologies, can conceal any amount of discreet gadgetry within the fabric, and billows behind one in an appropriately dramatic manner as required. (Whether or not there is any wind, this can be arranged.)
Don’t go looking for trouble without one!
(That special variation that is the sadly-not-yet-troped Badass Labcoat will be covered when we get to Science Hero.)
