AIR BORDER / a hat for invisible mask


Masks reduce the risk of viral attack, but they also cause many inconveniences in life, such as increased breathing resistance and interference with vision. These problems discourage many people from wearing masks and increase the spread of viruses. AIR BORDER is designed as a sport hat. The narrow slit at the brim emits high velocity airflow, forming an air barrier around the user's mouth and nose. The airflow barrier blocks outside gases and prevents viruses carried by others from entering the user's respiratory tract through air exchange.
