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. 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, more like way two much. Single layer, just right. Airpill on there? Even better. BTW, you had me at kid spit.
