Sportsman’s Headnet Has Window (Apr, 1931)
Sportsman’s Headnet Has Window
FOR use by fishermen when harassed by black flies, gnats and mosquitoes, a head net now on the market has a non-breakable, non-combustible window for providing a clear view. The net is attached to a folding steel frame and will fit any hat.
Unless the entire net is fireproof your going to have more to worry about than black flies when you light up!
