How does period underwear work?

Period underwear works through four smart layers. A moisture-wicking top layer pulls wetness away from your skin so you feel dry. An absorbent core soaks up and holds your flow. A leak-proof barrier stops leaks reaching your clothes. And a soft, breathable outer keeps everything comfortable.

Different styles hold different amounts, described as absorbency levels — Light, Regular, Heavy, and Overnight — just like pads come in different sizes. You pick the level that matches your flow, wear it like normal underwear, then rinse and wash it for reuse.
