EcoHelmet is a fully functional cycling helmet made from cardboard paper that folds up to the size of a plantain. The helmet is designed to be an item that people carry around with them at all times, letting them stay safe in the event that they'd need to hop on a bicycle at short notice.
Though it might seem odd for one to jump on a bike unprepared, not all riders on city streets use their own bikes. Many metropolises have introduced bike-sharing programs in which riders pick up and drop off bikes at checkpoints around the city. While such a system offers many benefits, one of the major drawbacks is that people who use bike-share programs often don't bring helmets with them. At just $5 retail and with a discrete, foldable design, EcoHelmet is the ideal supplement to a strong bike-sharing infrastructure.
