The classic that started it all. We didn't invent this type of face mask. But when we decided to make a single layer acrylic mask, we did something different. Everything we'd ever seen up until that point was a double layer face beanie that would have a Florida man's face sweating in Antarctica. And soak up twice its weight in kid spit. Two layers = way too much. Single layer? Just right! Airpill on there? Even better. BTW, you had me at 'kid spit.'
