    Very pleasantly surprised by the comfort and effectiveness of these period wear panties, I gave up the menstrual cups. We can have apprehensions at the beginning (we have never dared to ONLY wear panties during our periods), fear of spending the night with them... But in the end the result is great.

    I have a very positive opinion on my purchase of period knickers for medium flow! It is pretty, discreet, comfortable and protects me well during my periods. For my first day of period I use the heavy flow panties. I had taken a size M, which I usually take for my underwear. The best alternative to the usual protections.



Five years ago a silent revolution was born. It was the beginning of Smoon, a brand of underwear and technical clothing dedicated to the well-being of women, combining comfort and performance with respect for the body and the environment.

Today we celebrate 5 years of sassy women. First of all, Mathilde, its intrepid founder who dared to dream of a revolution and support women at every stage of their lives. But also all the women who are part of this story. Those who were the pioneers and dared to take the plunge from the start, those who converted their friends, those who guide us every day to improve...

Together, let's continue this little revolution by innovating and creating solutions that celebrate femininity in all its forms.

And for his 5th birthday: A free pair of 'casual' socks from 80€ of purchase

We talk about Smoon at Les Maternelles

The France Television show Les Maternelles selected Smoon and Marie Perarnau presented one of our menstrual underwear in organic cotton, for medium flow, equivalent to 2 or 3 tampons. Her advice? Buy period panties to try out and get an idea of ​​this alternative to the usual period products.

Not just for periods

Youtuber Allweneedislove, for example, tells us that period panties look like any panties you might find in your closet . But also that everyone can use this type of brief because these hygienic protections can be used for abundant white discharge, urinary leakage, return of diaper, postpartum etc.

Reasonable price and very comfortable

Another Youtuber, Myrtilla tells us how "very very very comfortable" Smoon period pants for women are and highlights the fact that we also offer models for teenage girls.

Besides absorption, its strenght resides in the absence of seams!

Finally, let's zoom in on the chronicle of the Youtuber Mes Menstruelles which highlights our Séléné period pant and its glued edges, extra-flat and therefore invisible under clothing.

5 arguments to take the plunge

Smoon has its own Youtube channel where we give you, for example, 5 shocking arguments to justify the price of menstrual panties:

  1. Our materials : we have chosen quality materials, and above all durable, certified Standard 100 bye OEKO-TEX.
  2. Manufacturing : our seamless technology took us to Tunisia, a neighboring country known for its know-how in textiles and more specifically in the manual manufacture of underwear. In addition, all our menstrual knickers are sent by boat and not by plane to limit our ecological impact.
  3. Our tests : all ourmenstrual underwear are tested by panels of testers and also by independent laboratories, in order to guarantee the lifespan, absorption and effectiveness of our products.
  4. Medium/long term savings : for a normal flow, it is said that 4 protections are needed per day. We multiply by 5 for a complete cycle, i.e. an annual budget of €45.50 or €136.50 over 3 years. For the same period, 3 menstrual panties may be enough, i.e. a saving of €46.50. Not to mention the underwear and sheets that will be stained and may have to be thrown away.
  5. A gesture of solidarity : 1% of our turnover is donated to the Maisons des femmes de Saint-Denis, which helps women victims of violence.
