Thinx makes underwear that has the look and feel of your favorite pair, but with a built-in thin cloth menstrual pad. You just rinse in the sink at the end of the day, then stick the underwear in the wash with your delicates and hang to dry. These Hiphuggers hold about two tampons worth of fluid for heavier days. And they’re also good backup if you’re using a tampon or, say, getting into the groove with a menstrual cup.
