People often have souring neck and shoulder due to the lack of neck support during commuting. Although neck pillow may be a straightforward solution, it is hard to be carried around. Scarf X is a scarf-like neck pillow. By making more than 30 prototypes, Scarf X can provide better support and it is 86% smaller and 65% lighter than the normal ones. This project is in the final of our school Entrepreneur Days’ competition.
