There's a new pair of underwear for men out there that claims to filter the stink out of your farts. They're called Shreddies and they use a technology called Zorflex, which is an active carbon cloth originally developed by the British Ministry of Defense for use in chemical warfare suits. In the case of Shreddies (not to be confused with the cereal Shreddies), it's for making your flatulence smell fresh as roses. The kicker? They're kind of expensive, at $40 a pair for guys (they're cheaper for women, but I still subscribe to the theory that women don't fart).
So fart away, Bros! We shall call these our baked beans pants. Via the official press release:
Shreddies flatulence filtering underwear features a ‘Zorflex’ activated carbon back panel that absorbs all flatulence odours. Due to its highly porous nature, the odour vapours become trapped and neutralised by the cloth, which is then reactivated by simply washing the garment.
