Why is the inner lining made of organic cotton safe for me and the environment?

"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."

Our tips for washing

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.

The Period Guide

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 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 👇🏼."

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’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.

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 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.

Do I need to wear a tampon or a pad in addition to my Mutandine Mestruali?

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."

How does Sisters Republic commit to ethical manufacturing?

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).

What are the delivery times and return conditions?

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 👇🏻.

A natural composition for the protection of your body

Intimate hygiene for women and hygienic period products are at the center of our thinking and actions. All materials used to make our Mutandine Mestruali are either made from certified organic cotton. This means that all our period panties are guaranteed to be free from toxic substances or additives that could be harmful to your health or the environment. When you use skin-friendly Mutandine Mestruali, you have a product that protects both your body and the planet. Here you know what kind of fabric comes into contact with your mucous membranes, unlike certain disposable period products (tampons and pads), which have questionable compositions. These period products are in some cases responsible for irritations caused by harmful substances and can sometimes even be dangerous to your health (e.g., the risk of bacterial infection, also known as "toxic shock syndrome," in 2017, 23 women were affected, and their number has been steadily increasing in France since 1990).

Sisters Republic Period Underwear: Like regular underwear, only better

Our menstrual panties will make you forget your period: Thin, odor-neutral, highly absorbent, and leak-proof thanks to their moisture-proof layer. They are worn like regular underwear, and there are many pretty models, with small ruffles or polka dots. Bikini cut, classic brief, or shorty version, underwear for every taste, from flirty to sporty. With our period underwear, you will feel comfortable all day and even throughout the night, light, relaxed, and simply pretty. Choose your desired design, size, and the absorbency tailored to your flow, and try out our new protection for intimate hygiene. A real alternative for your menstrual cycle that you simply have to test!

Period underwear that saves you money and protects the environment

Finally, no more tampons and sanitary pads to throw away every month. With the Sisters Republic Mutandine Mestruali, you save money every month and help protect the environment. There is almost no waste created, as our period panties are washable and reusable for many years. To ensure your period panties last a long time, simply rinse them under the tap immediately after taking them off and then wash them in the machine at 30°C with your usual laundry. Let them air dry afterwards. You can use a laundry bag as additional protection for your menstrual panties, but this is not strictly necessary. Your Mutandine Mestruali is mainly made of a nylon/elastane blend, a soft, durable, and comfortable material that is also commonly used in sportswear.

Choose the period underwear that suits you and your cycle.

Regardless of your menstrual cycle, whether you have a rather heavy, medium, or light period, whether you are at the beginning, in the middle, or at the end of your period, whether you are looking for additional protection to your conventional intimate hygiene products or want to replace them, Sisters Republic will always have the right Mutandine Mestruali that perfectly meets your needs. All our period panties come in 3 absorbency levels to adapt to the needs of every woman: Light, Medium, and Super, as well as in all sizes! This way, you can wear our sexy bikini with absorbency level "Super" even at the beginning of your period and even during heavy menstrual flow. Or you can wear our Shorty "Light" to exercise at the end of your period and do so with a comfortable feeling, thanks to the thin fabric layer and being completely leak-proof.

Period underwear for all situations and needs

Our washable and absorbent period panties can of course also be used for vaginal discharge, white discharge, or urinary loss (light incontinence). We recommend using the underwear just like you would during your period, except that you do not have to rinse them immediately after use with cold water, but can wash them directly in the machine after taking them off. With Sisters Republic you have finally found your Mutandine Mestruali that is 100% efficient, comfortable, practical, eco-friendly, and sustainable! Just choose your size, the absorbency level Light, Medium, or Super and change the rule(s) too!
