Brilliant Design!
I drive a delivery truck. In and out all day long, but can't stand to wear a mask while driving. This was the answer to my problems... always have it with me, but don't have to wear it when I don't need it. Very comfortable t-shirt material. The filter pocket is awesome. Adult male, wear a 2XL shirt (provided for reference) and the standard adult size is large enough.
