Flat-D

Embarrassment, not necessity, is the mother of inventions:

Brian Conant stood alongside his fellow National Guardsmen during a training session about eight years ago in Hawaii. He was wearing a heavy chemical warfare suit lined with charcoal.

"Any time I expelled gas in the suit, I realized nobody could smell it," Conant, 48, says. "It was amazing."

...But with Conant's invention, the Flatulence Deodorizer, also known as Flat-D, there is an alternative way to limit the embarrassment.

The long, narrow washable pad, lined thinly with charcoal, absorbs chemicals, including hydrogen sulfide, a byproduct of the bacteria that causes odorous gas. The pad, at $12.95, curves with the contour of the body, and one size fits most.
