Like it or not, everyone farts, and they do it far more than you’d think. Healthy people pass gas up to 20 times a day, and, as we recently learned, even if you try to hold your farts in, they’ll come out one way or the other—possibly through your mouth. Depending on what you eat and where you pass it, that can get pretty smelly. That is, unless you’re wearing fart-proof pants. A UK-based company called Shreddies makes “flatulence filtering” jeans that promise to eliminate your worst smells before they can escape into the wider world, Business Today reports.
Shreddies products are lined with activated charcoal, a substance that’s great at absorbing odors and gases—so much so that it’s a go-to ingredient for home air filters and purifiers. According to Shreddies, the odor-absorbing qualities of the fabric last around two to three years, at which point you’d probably be buying new jeans, anyway.
You still have to mind your farts, though. The company says that to be effective, the jeans have to fit tightly against the skin, ensuring that your gas is absorbed directly into the fabric. “To avoid flatulence escaping around the filter we recommend that you stand with your legs together and try to let your wind out slowly,” the Shreddies website instructs (emphasis theirs). “When sitting, keep your knees together so that flatulence escapes through the carbon panel.” As long as the jeans fit correctly, the filter should absorb all the foul odors leaking out of your body.
