Directions for use
Depending on how heavy your periods are and the level of absorption you choose (light, medium or super), your Sisters Republic panties can replace your tampons, sanitary pads, cup... or be used to reinforce them. For example, if you have a bleeding period (copper IUD, endometriosis, hormonal imbalance...) and you want a 100% leak-proof guarantee, you can slip on your Sisters Republic panties in addition to other protection and get through the day with complete peace of mind. Or you can use your Sisters Republic panties on their own, but only from day 3 of your period, when the heaviest days have passed.
If, on the other hand, you have a normal to light period, you can use your Sisters Republic panties on their own throughout your cycle, for up to 12 hours at a time, without any risk of leakage, odor or wetness. All you need to do is adapt the degree of absorption of your panties to your current flow: Super absorption for the start of your period, Medium for the middle of your period and Light for the end of your period.
And to find out exactly how long you should keep your panties on, simply rely on how you feel, and change them as soon as you feel a slight dampness. But here are a few pointers to get you started:
And for your first use, don't forget that it's best to start by testing at home, quietly, to see how it goes and understand your flow.
To maximize the absorbency of your panties, we recommend washing them 2 times before use. Then, to make them last as long as possible - because Sisters Republic period pants are washable and reusable for many years - we recommend :
1/rinse your panties in cold water as soon as you remove them, until the water runs clear.
2/wash it in the washing machine on the 30°C synthetic program (or by hand) with the rest of your laundry (I promise, everything will be fine :-)). If you don't have enough laundry, you can use the Sisters Republic 3-in-1 pouch to store your rinsed panties while you wait for your next wash - that's what the pouch is for :-) .
Do not use fabric softener or bleach.
Ideally, put your panties in a laundry net when machine-washing or in the Sisters Republic 3-in-1 pouch, which doubles as a laundry net.
3/let it air dry and do not use a tumble dryer.

Tips for composing your pack
Depending on the length of your cycle, short or long, you'll need between 4 and 10 panties. If you want to wear your menstrual panties day and night, and wash them all at the same time at the end of your cycle, you'll need between 8 and 10 panties. If you want to wash them so you can reuse them several times during your cycle, 4 to 5 panties will be sufficient. You'll need at least one panty for the day and one for the night, multiplied by the number of days of your period.
