摘要： This application is for an improved face mask that allows users to easily transition between a full-protection mode and a partial-protection mode. In full-protection mode, the improved face mask covers a user's mouth area and nose area. In partial-protection mode, a mask hatch removably attached to the mask frame is detached and exposes the user's face covered by the mask frame. A method of manufacturing the improved face mask is also described.
