I haven't found another one of these with the mesh front, as well as back.

The sides are polyester, no foam

There is light staining on the forehead band.

Everything else is clean as a whistle.

The button on top is made of hard plastic.

There is no interior maker tag or info printed on the snap.

1 tiny hole inside, see photo. Not seen while displayed.

Smoke free
