The complete care package for your period underwear, before, during, and after your period!
Our package consists of:
Tips for Using the Soap: First, dampen your period underwear with cold or lukewarm water💧 and then apply the wet soap🧼. Let it sit for 10 minutes and then gently rub the fabric together. Afterwards, you can wash the underwear by hand 🫱🏽 or in the washing machine. This product is not intended for gynecological or cosmetic purposes.

This way, you take no risk, so GO! GO! GO! To learn more about this offer, just click below on "Satisfied or Money Back".
To maximize the absorbency of your period underwear, you should wash it twice before use. To ensure it lasts as long as possible – because Sisters Republic period underwear is washable and reusable for several years – we also recommend:
1/ Rinse the underwear with cold water immediately after taking it off until the water runs clear.
2/ Wash it with the "synthetics" program at 30°C with the rest of your laundry (don't worry, everything will be fine).
We recommend placing your period panties in a laundry bag or in the Sisters Republic 3-in-1 pouch when washing in the machine. Do not use fabric softeners or bleach.
3/ Let air dry and do not use a dryer.
Don't have a washing machine? Use our stain remover soap, which protects the absorbent fabric of our underwear.
I recommend it 100%
"This is the first time I have bought period underwear and I am completely satisfied! For heavy menstrual flow, I used the one with absorbency Super and no leaks (even at night!) I recommend it 100%"
Marine T.
Thank you, Sisters Republic!
"It is a real innovation for all women. You experience your period differently with it, I no longer feel uncomfortable like with tampons or cups. The period panties in the pack have different absorbencies, so you have the right protection for every day."
Camille S.
They are really thin and comfortable
"I have a light blood flow because I take the pill, so for the heaviest day I took a slip with absorbency Medium just to be safe, and for the rest of the time two pieces in "Light." I have the impression that I no longer feel my period because the underwear is so thin and ultra-comfortable. I can wear them all day without worrying, ..."
Annabelle M.
Pleasantly surprised
For someone who only uses tampons, it felt a bit strange at first... I was afraid something would leak, but that doesn't happen. The panties absorb all the fluid very quickly. I'm so glad I don't have to use tampons anymore, especially at the end of my period when it's really uncomfortable!”
Céline R.
It's great
"What is really great is the material, I feel completely comfortable. I chose the strength "Super", even though I have rather average blood flow, but I wanted to be sure that nothing leaks."
Camille.N
Underwear that is now indispensable
"Essential is the adjective that comes to mind when I think of period underwear. The underwear is very comfortable, the blood absorption is good, and above all, you have peace at night. Thank you very much for these efficient and comfortable panties that almost make you forget you have your period!"
Maude.K
I recommend it without hesitation
"It is truly an innovation for all women. I experience my period very differently today..."
Morgane F.

Ultra absorbent and antibacterial fabric.
Breathable lining made of organic cotton.

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

Yes, it was specifically designed to be washed directly at 30°C on the delicate or synthetic program to protect your briefs and extend their lifespan.
