This High-Tech Underwear Could Help Girls Around the GlobeHow one woman is rethinking menstruation maintenance with Thinx

Don't tell Miki Agrawal that Thinx, her line of underwear designed to let women menstruate freely without tampons or pads, might not be for everybody. Agrawal fiercely believes -- to quote Thinx's tagline -- that these panties are "for women with periods." Meaning: all of them. "Girls are sick of wearing tampons," Agrawal says. "As a woman, how many pairs of our underwear have we all ruined from monthly accidents?"

She might be right: Since a big market push last spring, she says she's sold "tens of thousands" of pairs of Thinx, which look like normal underwear. According to Agrawal (and a few enterprising bloggers), they feel like regular underwear, too. But unlike your daily underpants, these are antimicrobial, moisture-wicking, liquid-absorbing garments that took three and a half years to develop. They come in six styles, cost from $24 to $38 each and promise to hold up to two tampons' worth of fluid.
