Does period underwear work for heavy periods?

Yes — Heavy and Overnight styles are made specifically for heavy flow and can hold the equivalent of several pads. They keep you protected and dry for hours, which is a relief on your heaviest days.

On very heavy days, you can also use period underwear as reliable backup alongside a tampon or menstrual cup, and keep a spare pair with you in a discreet wash bag so you can change when needed.
