AS-Guard is a disposable underwear cover designed to provide an additional layer of protection from bacteria and dirt left behind on chairs and seats. Moisture, sweat, and bacteria can be left behind on public seating surfaces, where they can potentially be picked up by the next person who sits down. AS-Guard provides a discreet layer of protection for sensitive areas when sitting on public transit, in restaurants, on outdoor seating, and other places where seating surfaces cannot be cleaned between uses.
