300,000+ sisters are convinced by our period underwear.
I recommend it 100 %.
"This is the first time I have bought Mutandine Mestruali and I am completely satisfied! During heavy menstrual bleeding, I used the ones with absorbency Super and there was no leakage (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 I did with tampons or cups. The period underwear in the pack have different absorbency levels, so you have the right protection for each day."
Camille S.
"You are really thin and pleasant."
"I have a light flow because I'm on the pill, so I've taken a panty with absorbency Medium for the heaviest day just to be safe, and for the rest of the time, two in 'Light'. I feel like I can't even feel my period anymore because the underwear is so thin and ultra-comfortable. I can wear it all day without worrying, ..."
Annabelle M.
Pleasantly surprised
"For someone who only uses tampons, it felt a bit strange at first... I was afraid that something would leak, but that doesn't happen. The panty absorbs all the fluid very quickly. I'm so glad I don't have to use a tampon anymore, especially at the end of my period when it's really not comfortable!"
Celine R.
It's great
"What is really great is the material, I feel completely comfortable. I chose the strength 'Super', even though I have a rather average blood flow, but I wanted to make sure that nothing leaks out."

"Underwear is no longer to be imagined without."
"Essential is the adjective that comes to mind when I think of Mutandine Mestruali. The underwear is very comfortable, the blood absorption is good, and above all, at night you can have your peace. Thank you very much for these efficient and comfortable panties that almost make you forget that you have your period!"

I recommend it without hesitation.
"It is truly an innovation for all women. I experience my period very differently today..."

What to put in my pack?
If you want a pack that covers the entire duration of your period and therefore be worry-free for 5 to 7 years, you can either create a pack of 3 or 4 if you want to wash your panties during your period, or a pack of 7/8 if you only want to wash them at the end of your period. In this latter case, we recommend 2/3 SUPER absorbency panties, 3 MEDIUM absorbency panties, and one LIGHT absorbency panty. Know that for the night, the Boxer shape is ideal because you can sleep with just a T-Shirt on top since it covers like a short!

What tips are there for a first test?
"For a first test, we recommend wearing the underwear at home in peace starting from the third day of your period. If everything goes well and you feel comfortable, you can wear the slip all day at work or school, even on the heaviest day, as long as you don't have a hemorrhagic bleeding (copper IUD, endometriosis, hormonal disorders, etc.). And don't forget, for your 1st period slip, you can take advantage of the "Satisfaction or Money Back" offer, details below on the website 👇🏼."
How do I choose my size and the level of suction strength?
"Our underwear is known to be normally cut, so we recommend that you choose your normal size. You can also refer to the size chart found in the product descriptions. If you are between two sizes, it is better to take the larger model, as one does not want to wear tight underwear during menstruation."
How long can I wear my Mutandine Mestruali?
Most women can wear their Sisters Republic underwear for 12 hours straight, even on the day of heaviest discharge. Some women who have very heavy discharge (copper IUD, endometriosis, hormonal disorders, certain menstrual bleeding in their teenage years...) may find it difficult to wear the panties for 12 hours on the day of heaviest discharge and will likely need to change them once to avoid the feeling of moisture. Alternatively, one can start the day with additional protection like a cup or tampon and only wear the underwear by the end of the day. In any case, even women with heavy discharge can usually keep wearing the Mutandine Mestruali continuously on the other days.
How does Sisters Republic commit to ethical manufacturing?
"No, nothing else needs to be used, as our underwear can absorb the equivalent of one and a half tampons (in the LIGHT versions) and up to three tampons (in the SUPER versions)."
"However, if you suffer from bleeding disorders (copper IUD, endometriosis, hormonal disorders, certain menstrual bleeding in your teenage years...) and would like to wear an additional hygiene protection on the heaviest day for safety, this is of course possible."
How does Sisters Republic commit to ethical manufacturing?
From the selection of fabrics to the production of our Mutandine Mestruali, transparency and the desire for as ethical a production as possible play an important role for us. All our fabrics, lace, and elastic bands come from the Mediterranean region (Spain, Italy, Portugal, Turkey) and are either GOTS-certified organic fabrics or free from harmful substances for the body and the environment. Our underwear is designed in France in our Paris offices and then produced in Morocco in our BSCI-certified workshop (the Business Social Compliance Initiative is an organization that audits companies to ensure that the working conditions of employees regarding wages, vacation, safety, etc., are satisfactory).
What are the delivery times and return conditions?
The preparation time for your order is 24 hours. After that, the delivery time in mainland France depends on the order day and the chosen shipping method, ranging from 48 to 72 hours (business days). When placing the order, you will be informed of an estimated delivery date. You can find more information under the "Payment and Delivery" section at the bottom of the website 👇🏻.
