"I just think it's a shame that there isn't a super-practical thong or tanga shape on tight-fitting clothes. In the meantime, I'm using the boxer shorts, which don't make any demarcation on the buttocks, no marks, so they do the job well. Right from the start, what's really top-notch is the material, I'm completely at ease and comfortable, I took the "Super" level even though I have a rather average flow, because I wanted to be sure to avoid leaks."
Elizabeth
At first, I was puzzled by the idea that there could be no leakage, but in the end, I'm amazed by the result. I used the panties on New Year's Eve, and was able to keep them on for almost 12 hours straight (I have an average flow, and it was at the beginning of my cycle). There were no unpleasant surprises, and on top of that, I didn't feel dirty or damp at all, as if I wasn't menstruating.

"I had no idea how much I'd love to use ruler panties. I came across the site by chance, and after talking about it with one of my neighbors, I decided to take the plunge and give Sisters Républic a try, I've just tested them on my first cycle, and no lie, they've changed my life! Zero leakage on the 2nd day, wearing for 10 hours (Ginger super), The second day is often the worst, which is why I'm completely satisfied, (...) For all the skeptics, well, don't wait any longer! Sisters républic will change your life during your period Easy to clean, no odor, zero leakage, super comfortable day and night, you don't feel it at all It's just the best zero-waste purchase of my life, I recommend it 1000%".

The Sister's team has designed different packs to accompany you through your period.
The Starter pack is perfect for getting started with your new protection. It includes 1 super-absorbent Ginger boxer for the first few days of your period or during the night, 1 Colette panty with Medium absorption, ideal for mid-cycle, and a Sidonie bikini with Light absorption for the last few days of your period.
Who says you can't be sexy during your period? In the Girly Pack, you'll have 3 refined bikinis with lace trim. The first is Super absorbent for the first few days of your period, or on days when your flow is a little heavier, and 2 other bikinis with Medium absorption for other days.
More like classic panties? The Classic pack includes 3 ultra-comfortable menstrual briefs in a classic shape, but just as refined with their little ruffles at the waist. 1 super-absorbent Colette menstrual panty and 2 panties of the same model with Medium absorption.
For each of our packs, you can choose between 3, 5 or 7 panties. Other packs are available on this page, such as the Integral pack for 5 to 7 years of peace of mind.
Compose your pack by choosing the models of your choice.

For a single pack, you can choose not only several panty models, but also different degrees of absorption for the latter, so you can adapt your protection to your flow at different times of your cycle.
By opting for a pack, you'll benefit from 10 to 20% savings :
- 10% off for 3 pairs of panties
- 15% off for a pack of 5
