The shirt is really nicely printed.
The shirt is really beautifully printed and has a pleasant, soft fabric. The delivery was extremely fast; even though it didn't come from Germany, it still arrived within 1.5 weeks. This was my second order with Sisters Republic. I am very satisfied. Top products and fast delivery.

From skeptical to enthusiastic
At first, I was skeptical and felt a bit uncertain, as I couldn't imagine at all that you feel NOTHING at all. The feeling of well-being came immediately. I am thrilled, convinced, and have already ordered more. Finally, the annoying tampon changing has come to an end.
Magda R.
A gain for every woman
"It's a shame that I spent decades using tampons and pads. The menstrual pants not only look stylish and are comfortable, but they also fulfill their purpose absolutely satisfactorily. Nothing leaks, nothing smells unpleasant. I now have three pairs, that's how satisfied I am."
Franziska N.
Never again without my period panties
"They feel very comfortable. I chose 2 different suction strengths. Since I have a really heavy flow in the first two days, I need to combine the panties with a menstrual sponge at the beginning. After that, I can use the panties without additional protection. They also don't show through tight clothing. Simply great. I especially love the different designs of the models. Thank you for your wonderful products that make every woman's period a little more pleasant."

Great briefs for teenagers
"I ordered the panties for my teenage daughter - she is very excited and feels very comfortable with the panties - plus they look very neutral, if not even cool. A great idea and a super alternative to pads, tampons, and the like."
Hilda F.
Purchase recommendation - very satisfied
"I am very satisfied with the panties - good absorbency, good cut, and comfortable to wear. I bought 3 different models in all different absorbencies and feel secure and well taken care of in each one. From now on, they will definitely replace my tampons/pads. Great! 😁 Clear purchase recommendation for anyone who cares a bit about the environment and doesn't want the hassle of changing tampons, etc., or can't use tampons and doesn't want pads. The 'investment' is worth it!"
Adelheid M.
Completely relaxed
"I use the Boxershorts that leave no marks on the butt, so they serve their purpose well. From the start, the material is really top-notch, I feel totally comfortable and at ease, I chose the level "Super" even though I have a rather average flow, because I wanted to make sure I wouldn't leak."
Melanie L
It is actually very fine.
"I have a light discharge because I take the pill. That's why I chose a "medium" slip in the right size for the heaviest day, just to be safe, and two "light" for the rest. I feel like I won't get my period anymore because the slips are so thin and super comfortable. I can wear them all day without worries, ..."
Hannah K.
Pleasantly surprised
"I, who have only used tampons, found it a bit strange at first..., I was really scared that something might leak. But actually nothing, the menstrual pants absorb all the fluid very quickly. I'm so glad that I don't have to use a tampon anymore, especially at the end of my period, when it's just not comfortable!"
Jana L.
Slip Indispensable
"It is a very comfortable slip that absorbs a lot of liquid and allows you to have peace, especially at night. Thank you for these efficient and comfortable slips that almost make you forget that you have your period!"
Cacillia M.
Thanks to our 3 suction strengths, the Mutandine Mestruali adapts to the current menstrual flow. So you can enjoy life in peace.
The ultra-absorbent fabric channels the liquid into the interior of the underwear to ensure dry comfort on the surface.
"Our underwear is made from breathable fabric and naturally antibacterial bamboo fibers, which prevents unpleasant odors - unlike most pads, which are made up of 80% plastic."
All materials used in our slips are either organic certified or are guaranteed to be free from harmful substances that could be dangerous for you and the environment.
Our period underwear is washable and can be reused for many years - that means less waste for our planet.
"With our products, we say stop to disposable women's pads that cost a lot of money and end up in the trash. Our underwear is designed for all women and lasts 5 to 7 years. With a single pair of panties, 2275 tampons can be saved over 7 years."
The period underwear offers secure protection, thanks to the three highly absorbent layers that are processed inside and extend up to the top of the buttocks.
Moisture-proof material against leakage.
Ultra strong and antibacterial fabric.
Breathable lining made of organic cotton.
A breathable lining made of organic cotton that feels very soft on the skin.

"All our slips are lined with organic cotton on the inside, so that the contact of the fabric with the intimate area is soft and 100% safe for health."
"Our organic cotton is also very breathable and wicks moisture away into the interior of the slip to ensure a dry feeling on the surface and to avoid odors. This is the difference from conventional pads, which are often made of over 80% plastic (a non-breathable material that promotes the growth of bacteria and thus odors)."
"By using organic cotton, we can also limit the environmental impact of our underwear, as the cultivation of cotton is responsible for nearly 25% of the global use of pesticides."
"Furthermore, the other processed materials, i.e., they are guaranteed to be free from substances harmful to the body and the environment."
Caring for our underwear is very simple:
1 - Rinse under cold water until the water is clear after use.
2 - Wash at 30°C in the washing machine with the rest of the laundry (or by hand in lukewarm water).
3 - Simply let it air dry.

Learn more"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 panty all day at work or school, even on the heaviest day, as long as you don't have heavy bleeding (copper IUD, endometriosis, hormonal disorders, etc.). And don't forget, for your 1st period panty, you can take advantage of the "Satisfaction or Money Back" offer, details below on the website 👇🏼."
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’s better to take the larger model, as you don’t want to wear tight underwear during your period. As for absorbency, the menstrual flow changes during the period. It’s best to take two models in SUPER for the heaviest day and night, one MEDIUM for the middle of your period, and one LIGHT for the beginning or end of your period. If you only want to buy one model at first, choose SUPER (that way you’re on the safe side 😉). Unless you have a contraceptive that significantly reduces menstrual flow, then MEDIUM may be sufficient.
Most women can wear their Sisters Republic underwear for 12 hours straight, even on the day of heaviest flow. Some women who have very heavy flow (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 flow and will likely need to change them once to avoid the feeling of dampness. Alternatively, one can start the day with an 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 flow can usually keep wearing the Mutandine Mestruali continuously on the other days.
No, nothing else needs to be used, as our underwear can absorb the equivalent of one and a half tampons (for the LIGHT versions) and up to three tampons (for 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."
From the selection of fabrics to the production of our period underwear, 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 BIO 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).
The preparation time for your order is 24 hours. After that, the delivery time in metropolitan France depends on the day of the order 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. For more information, please refer to the "Payment and Delivery" section at the bottom of the website 👇🏻.
