If you ever visit a touristy town you often find they operate a shared bike system. The bikes are available for use within the town and you pick up and drop off at bike stations. The problem is as a tourist, you probably don’t have a helmet with you.
Over to these guys and their ultra-strong, disposable paper helmets. So strong, in fact, that they can survive a drop hammer, people stomping on them — or contact with the hard top. Oh, and they’re made from recycled (geddit?) materials.
