Maps are among the more invaluable travel tools. Android/iPhone apps are nice, but sometimes analog is just the best way to go. Industrial designer Emanuele Pizzolorusso has these Tyvek city maps in the pipes that look like they can handle anything you throw at them.
These maps are waterproof, crease-able, crumble-able, and when you’re done reading one, just stuff it haphazardly into the included pouch. They’re probably more useful to a hitchhiker than his or her towel. Emergency blanket, tarp, hull patch, the uses are endless. I only see concepts for London, Paris, New York, Tokyo and Berlin, and no word on when we can expect to find them in the wild.
