We’re pretty tired of shelling out hundreds of dollars a year on tampons and pads—not to mention their negative environmental impact. So when we learned that special underwear for periods works just as well as its disposable counterparts, we were kinda excited (yes, even about that time of the month).

Just like tampons and pads, period underwear works by absorbing menstrual blood. And no, they aren’t bulky or diaper-like at all (we promise). They look just like your fave thong or boy briefs, but they’re made from super-absorbent fabric to keep you feeling dry and leak-free. Most pairs can hold as much as two to three tampons, which means they’ll last the whole day. And if your flow is super heavy, they work as an alternative additional absorption option to whatever you might've been doing before (cough cough: wrapping your sweater around your waist).

But not all period underwear is created equal. And the last thing we want is a pair that underperforms. So we did our research, scoured reviews and found the best of the best. Here are the 14 best period underwear for every need—heavy, light and all the days in between.
