Ever been someplace wearing nothing but your underwear, and don't know where to put your keys? I know it's happened to me a brazillion times, and now there's a Kickstarter that is selling just that. I suppose they're good for preventing pickpockets, but I always carry too much crap in my pockets, I'll either give the wrong impression or injure myself. Any which way, this guy roadtested them, in case you're wondering how they work.
