I'm a big fan of "The Expanse" series of novels. The stories are being adapted into a television series by the SyFy channel, but don't hold that against them. The first two novels are outstanding semi-hard science fiction, and the second features one of the best portrayals of the thought processes of a power armored soldier ever written. Sadly, the overall quality steadily declines as the series progresses.
Concept artist Rob Cavanna was commissioned by a fan to design a costume for Amos Burton, a hard-assed engineer aboard the corvette "Rocinante". That included not only basic clothing and gear, but a selection of custom designed patches. The results are pretty awesome, and you really need to click through to see the high resolution image.
I've loved this kind of detail oriented, lived-in future since "Alien". That's the first media property I can think of where logos and signage were an important part of the production design. Mike Jenkins has recreated dozens of examples over at his blog. Browse around and you'll find designs from the "Alien" series, "Blade Runner", "Firefly", and more.
