there is another company that is making masks that has a pocket for the filter..and you can customize the mask with your logo or whatever you want..but they are expensive
Those mill gear masks would be EASY to make....with old DriWeave leightweight jackets or shirts/shorts, etc.
I’m going to see if hubby’s company has any old ones (in storage) with the company logo.
They always throw out (or just keep in storage) older designs when they order new products. The logo stays the same, though.
