Period underwear

Key facts about period underwear:
  • Period underwear provide all-in-one protection.
  • They are reusable, sustainable, and available in different styles and absorbency levels.
  • Period underwear can be used for sports, swimming, overnight protection, and replace internal and external products like pads or tampons.

Like pads, cups, discs and tampons, the goal of period underwear is to collect menstrual flow, keep wearers dry, and offer leak-proof protection. Period underwear offer a comfortable and eco-friendly alternative to traditional period products like pads and tampons.

Period underwear options

Period underwear are available in a range of styles and absorbency options. Styles include bikini-cut, high-waisted, boyshorts, thong, briefs, and maternity. Most styles come in various absorbency levels for light, heavy, or moderate flows.


How to use period underwear

Period underwear are worn just like a regular pair of underwear.

They're usually made with moisture barrier that keeps you feeling dry and an extra layer meant to prevent leaks.

Choose a pair that fits you comfortably, not too tight or too loose.

Certain types have a space that holds a pad. This is useful for overnight protection from leaks or stains.

Remember to change and clean your period underwear every 12 hours, or more often if necessary. Many types of underwear include an antimicrobial layer to minimize odor, but regular changing ensures you stay fresh.

Make sure to follow the washing instructions provided by the specific type and brand you use.
