What to put in my 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 need at least one panty for the day and one for the night, multiplied by the number of days of your period.

It‘s a whole new lifestyle…
Britany L
"I only got the period underwear recently, so my experience is not a long term one yet, but I absolutely love them! I genuinely feel like a whole new person during my period, because it feels so much better than everything else. I can move without feeling like I'm gonna leak or everything falling out of place, I feel light, and my mind is a lot calmer."
Best choice ever!
Jade R.
"I totally recommend them! I had been wanting to try "period panties" for some time but wanted to make sure to get the right one for me and now I am sure I made the right choice! So far so good, I really like Sisters Republic pants because they are super confi, discreet and girly-like. I bought 3 of them and I know it can be pricey enough...but I really think it is worth it as the quality is really good and they are so easy to clean. But most importantly, I like them because I they are environmentally friendly and I know I am contributing to less use of pads and tampons that are toxic for the planet…"
Fits perfectly
April N.
"I was afraid about the size but fits perfectly and nice looking panties. It’s best to buy 3 panties directly as it takes time to dry after cleaning (at least 1,5 day) It’s a new organisation that’s really interesting once we have it as it allows not to get scared to be out of protection. I found it easy to rince and clean."
Nice work !
Telma S.
"The Sisters Republic departure promise is clearly being kept. Comfortable, very absorbent and invisible! It is a great alternative to tampons or napkins, more hygienic and more ecological! I highly recommend the Republican Sisters panties which are really great!"
It’s the ecology. Period.
Mayline F.
"I bought these for my daughters who are scouts. Not only are they helping the planet (as girl scouts should) but they also enjoy a new found comfort and ease during their periods. So happy that we are finally evolving from pads directly to panties. Thank you Sisters!"
Comfy and reliable
Angelina M.
"When i have my period, all i need is comfy and secure. My new panties Sisters Republic are just like that : have my back for 24h hours (never tried longer), very comfy and cute as hell."
Top for the night
Florence B.
"I only use them at night for the moment because I haven't dared to leave all day with but really what happiness !! no need to stress anymore because of the tampon that we leave too long at night or to have the diaper effect with a maxi night towel. Now I just put on my comfortable panties and go to sleep! "
Very happy with the panty.
Samira A.
"The Panty is comfortable and looks also nice. I use it for the beginning and end of my period. This is working very good and I am using less tampon and other regular period stuff. I am very happy with it and going to buy another one."
Cannot change once adopted
Sophie P.
"So I have been a fan of the cup for several years, especially out of ecological conviction. So I naturally wanted to test the Sisters Republic period panties for the same reasons and I admit that I am more than convinced because, even if I had learned to organize myself with the cup, the real plus for me of these panties that's the practical side, no need for a sink nearby, no need for sterilization or anything. I put on my panties in the morning and rinse them at night and run a machine directly with my laundry. I feel that my cup will often stay in the cupboard!"
I love my new period shorts!
Abigail C.
"I love my new period shorts! I've been looking for shorts because there aren't that many shops where ypu can buy shorts, it's bikini most of the time. I bought 2 medium absorbant & 2 super absorbant and both work really well, I already tested them! Leakproof, comfy, good fit!"
the menstrual guide
Is it hygienic to wear period panties for 12 hours at a time?
Yes, because the fabrics used in Sisters Republic menstrual lingerie have been selected for their sanitary properties. Bamboo fiber is even a natural antibacterial. Only breathable organic and Oeko-Tex fabrics are used in our panties. Even after 12 hours, the pants remain hygienic and odorless.
Can I use my Sister Republic panties during sport?
Yes, your Sisters Republic panties are ideal for protecting you during sport because, unlike sanitary towels which can slip or fold, the panties-and therefore the absorbent part integrated into them-always stay securely in place. All our models are perfectly suited to sporting activities. However, we particularly recommend the sports boxer, as it's really interlocking and will follow your every move perfectly.
Do I have to change my panties during the day?
Because we know that changing panties during the day isn't very practical (you have to isolate yourself, take off your pants, etc.). Our period panties can be worn for up to 12 hours without leaking, smelling or feeling damp, so it's not necessarily necessary to change them during the day. However, if you have a hemorrhagic flow and feel the need to alter your panties in the middle of the day, our Mia panties can be unzipped at the sides, so you can remove them without taking off your shoes or pants.
Is it hygienic to soak in your own blood all day?
Firstly, contrary to popular belief, you don't soak in your own blood, because the 1st layer of fabric is breathable and dries very quickly. The airy weave allows liquid to pass quickly through the inside of the panty, leaving a dry feeling on the surface. The liquid is therefore directed, captured and retained by the absorbent fabric underneath, at the heart of the panty. Finally, unlike internal protection such as cups, tampons or menstrual sponges, period panties let the blood flow freely, so it doesn't stagnate in the vagina, which is the main cause of bacterial proliferation (and therefore of the very dangerous Toxic Shock Syndrome).
What are the delivery times?
Our panties are shipped directly from our French warehouses. Home delivery generally takes 24 to 72 hours and is free for orders over £80 (in mainland France). Delivery to a "point relais" can take an additional 24 to 48 hours, and is free from a purchase of £40 (in mainland France). When you place your order and select your shipping method, you'll be given an estimated delivery date.
Aren't menstrual pants more expensive than disposable sanitary pads?
It's true that it's an investment at the outset, but unlike other sanitary protection such as pads or tampons, menstrual panties are reusable and can last up to 7 years. A single pair of panties can replace 2275 tampons* (over 7 years). So menstrual pants really do save money in the medium term (* disposable protection saved ⇒ 5 tampons a day over 5 days of menstruation, 13 times a year (365/28 = 13) over 7 years = 2275). What's more, you'll find discounted packs in the store (-10% for purchases of 3 or more products, -15% for purchases of 5 or more products and -20% for purchases of 7 or more products), enabling you to place "group" orders, mixing different sizes and absorbency in the same basket.
