Design & Sourcing

Our underwear is designed in our Paris workshops.

We make a rigorous selection of our fabrics, laces and elastics, which come from Spain, Portugal and Turkey.

They are either certified organic and carry the GOTS label. Or OEKO-TEX certified, i.e. guaranteed free of substances harmful to the body and the environment.

Manufacturing & Testing

Manufacturing takes place in Morocco, in our local workshop, which complies with the strict BSCI code of conduct (fair working conditions for employees*), with regular inspections.

We often visit the production site ourselves to see the manufacturing process and the quality of life of the seamstresses. The packaging for our briefs is ecologically designed and made from 100% recyclable cardboard. What's more, our menstrual underwear is tested by an independent laboratory under gynecological supervision to guarantee perfect tolerance and absolutely convincing efficacy :-)

Our commitment to solidarity

To reinforce our ethical commitment, we have also set up the Sisters Solidaires which supports thousands of women around the world via 3 fantastic partner associations that help fight the taboo of menstruation and menstrual precariousness.

*The BSCI (Business Social Compliance Initiative) code of conduct guarantees workers' trade union rights, advocating freedom of association and non-discrimination. It also calls for good working conditions that ensure workers' health and safety, with decent working hours and wages. It prohibits forced and child labor. Finally, it is involved in battles that do not directly concern employees, as it fights to protect the environment.

The making of Sisters Republic menstrual briefs now holds no secrets for you!

All these steps are necessary to offer you a range of quality models (panties, classic cut, bikini cut, shorty cut, boxer cut, as well as menstrual swimsuit bottoms and tops) that are comfortable, leak-proof and odor-free. Models to suit women's busy daily lives, from school to work to sport, from quiet nights to hectic ones.

We do our utmost to make the menstrual cycle as comfortable as possible and offer the best alternative to external disposable sanitary pads and internal pads and cups, which can cause infections such as toxic shock syndrome.

We also regularly offer new innovations in our collection of accessories, such as our multipurpose pouches which enable you to store your menstrual pants, protect them during washing or carry your clean or used period pants in your bag without it getting stained.
