Abstract
The maskap is a safety mask that is worn like a cap, It has a thin rubber liner (or airtight material) that covers the inside of the cap. The rubber liner forms a seal when worn as a mask. There are two plastic eye covers that are sealed to the cap, that when worn as a mask will let the user see through them. On the brim of the cap but under the fabric is a filter box. The filter box has two air tubes molded to it. The air tubes run up the front of the cap. The open ends of the air tubes are sealed with the rubber liner. When the maskap is worn as a mask the user will breath through the filter box. There are elastic bands that are sewn to the cap at three or more points to hold the maskap on.
