Test your menstrual panties for 60 days

- Hmm… I'm not sure… They look cool, but what if they don't work for me?

-Aren't my periods too heavy?

- Plus, isn't it too complicated to wash?

- Are these panties really made for my bottom, and my bottom for these panties?

Good news!

You don't have to hesitate any longer, because now you can test the panties of your choice free of charge for 1 cycle!

That's right, for your first purchase at Sisters Republic, we're offering you the chance to try on your panties for free for 30 days. How cool is that?

And if it doesn't suit you, you can send it back to us within 30 days of purchase for a full refund.

You're not taking any risks, so GO! GO! GO!


Find the model that's right for you !

We offer models for women and teenagers, available in 3 absorbency levels (light, medium, super). All you have to do is find the one you like best... from classic briefs, high-waisted panties, cropped panties... or even boxer shorts! We're sure you'll love them 😊

  • This offer is valid only on one pair of panties already worn. No additional panties already worn may be returned for exchange or refund.

Can I return unworn panties?

No, you can send back one or more pairs of Sisters Republic panties that you haven't worn, but not in the same parcel as the 30 days test offer, as the return address and form are different.

Menstrual pants that are NOT being worn, i.e. that simply need to be changed or returned, should be sent to the address below with the following returns form (please ensure that they are returned in their original packaging) :
