Do I need to use one or more pairs a day?

If you're using the Sisters Republic underwear for your flow ("Light" for a light flow, "Medium" for a medium flow, or "Super" for a heavy flow), you can wear your underwear for up to 12 hours and change at night, or use another form of period protection.

However, if you are using "Light" absorption with a medium or heavy flow or "Medium" absorption for heavy flow, you will likely need to change your underwear after 3 to 6 hours to make sure you stay feeling dry. The table below summarises the number of hours you should be able to wear your underwear for maximum comfort, but the best thing is still to rely on your senses and to change your underwear as soon as you start to feel any dampness.

If you are using your period underwear for the first time, we suggest that you to test them at home in order to get an idea of how they work with your flow.

If your flow is very heavy, we advise you wear our underwear in addition to your other period protection.
