I do have an idea for face shields, I used to live in MN and was an avid snowmobilier, make visors as those snowmobilers wear only attach the plastic piece to a hat such as a baseball hat. The curve of the plastic piece would curve back from the bill protecting the side of the face too. I planned to turn this in to Article cat snowmobile makers and ask for a 50% cut . So this is officially my idea.
