If you use a Sisters Republic slip that corresponds to your flow strength ("Light" for light, "Medium" for medium, and "Super" for heavy menstruation), you can wear the slip for up to 12 hours and then change it in the evening or use another hygiene product.
However, if you use a "Light" absorbency panty liner during medium or heavy menstrual flow, or a "Medium" period panty liner during heavy menstrual flow, you should change the liner after 3 to 6 hours to continue feeling "dry." For your reference, the table below lists the number of hours you can wear the period panty liner with maximum comfort. However, the best approach is still to rely on your own feelings and change the liner as soon as you feel a slight dampness.
"We also recommend that you test the slip at home for the first use to better understand and consider your menstrual flow."
In case of very heavy menstrual bleeding, we recommend that you use other menstrual hygiene products in addition to our period underwear.
