It is about time...!!
I'll take a case of these (Not for me, but for a friend of mine).... honest.
Introducing Shreddies, an underwear for men and women that filters your farts so you don't have to blame the dog ever again.
Shreddies flatulence filtering underwear features a 'Zorflex' activated carbon back panel that absorbs all flatulence odors. Due to its highly porous nature, the odor vapors become trapped and neutralized by the cloth, which is then reactivated by simply washing the garment.
