Shreddies uses a layer of activated carbon to mask odors.

They come in multiple styles, for men and women.

Here is, more technically, how they work.

The company calls its odor-masking technology Zorflex.

What about the sound? Sadly, no, says the company: "Shreddies are designed to absorb odours, not to muffle the sound. Most flatulence sufferers are able to control the noise by altering their body position."

These High-Tech Underwear Keep Your Farts From Smelling

True world-changing innovation.

Scientists and innovators may be hard at work curing malaria or generating cheap renewable energy, but these issues--while important--perhaps pale in comparison to the work of a British man named Paul O'Leary. That's O'Leary has invented Shreddies, a pair of underpants that prevents the odor from farts from entering the nostrils of unsuspecting people nearby.

The underwear are available for men and women (there are also models for incontinence), and uses a layer of activated carbon cloth to mask odors. The porous nature of the carbon traps the smell, leaving nothing but roses for the rest of the world. All you have to do is wash it to reset the smell-trapping abilities. The company calls its miracle fabric "Zorflex" and says that it went through rigorous testing to determine its odor-masking abilities: "De Montfort University in the U.K. tested our new 100% activated carbon jersey cloth and presented their findings at the 86th Textile Institute World Conference." The Textile Institute World Congress accepts no half-assed fart-masking test results.

Shreddies start at $30 for women and $45 for men. As to the most important question, the company has some regrets, but also a note of advice: "Shreddies are designed to absorb odors, not to muffle the sound. Most flatulence sufferers are able to control the noise by altering their body position."

  • Charging a higher price for men's pants is discriminatory and even predatory but likely based on the need to exact revenge upon the most egregious olfactory violators over the history of mankind, especially in yoga class.

    This can simply be abated by using a thin pad of fabric that is inserted between the buttocks to provide a channel of porous material for the gas to travel through. The sound is largely caused by the repeated obstruction and opening of the path through which gas travels, creating temporary chambers of high pressure that then release small amounts of gas explosively. By creating an unobstructed channel from the anal opening to the exterior of the buttocks, gas will be able to travel without building up pressure that generates the sound.
    I call my new invention "the fart muffler"

    so what is the invention "The Fart Muffler" like a pipe that channels the gas from the anus to the fart odor purification charcoal before release into the public atmosphere. No sound no stink what a perfect gimmick

    wow....I'm buying my husband a dozen - he creates his own source of unrenewable energy. Are they durable enough to handle all butt scratching? and how were these tested? Can my husband crash test them - he will put them through the ropes.

    Nice idea butt with a big drawback: No more using a pair of underwear four days in a row (switching front to back, then flipping it inside out and again front to back).

    Once switched front to back, the whole purpose of the high-tech underpants is lost. And goodness forbid the inside-out flip if you smell what I mean!

    Brilliant! Fart anywhere and walk casually away . . . But I'll tell you something, there is nothing better than a real snorter to bring out a great stink and a ripper rasp! Then hang around to watch the sniffers - ha, ha!!

    Sorry but what? Shreddies are designed to absorb odors, not to muffle the sound? Get something soundproof! Jesus.....what if someone bought me these? And what's with the $15 difference? Male fart smells worse or what?
