What is period underwear?

Period underwear is underwear with absorbent, leak-proof layers built directly into it. It looks and feels like a normal, comfortable pair, but it soaks up your menstrual flow and keeps you dry — so you can wear it instead of a pad or tampon, or as reliable backup on heavy days.

Inside, period underwear has multiple layers: a moisture-wicking surface that keeps you feeling dry, an absorbent core that holds your flow, and a leak-proof barrier that stops anything passing through to your clothes. After wearing, you simply rinse, wash, and reuse it — a good pair lasts two years or more.
