This "MP3 Smart Jacket" isn't the most stylish or aesthetically pleasing thing in the world, but if you care more about function than form and have a lot of crap to carry around with you, well, maybe you'll like it. It's basically the straps of a backpack without the pack, holding your devices and gadgets in a series of pockets. Even better? It has built-in speakers for playing your music out loud.
There's absolutely no way to wear this and play music from its speakers without looking like (and being) a total jackass, but hey, who cares what other people think? You have gadgets to carry around! Who are they to judge?
