Menstrual bikini made in Quebec

  • A permanently integrated absorbent lining at the gusset
    • super discreet
    • Quickly absorbing menstrual blood without swelling in water
    • hiding a thin waterproof layer for waterproof protection without the risk of leakage in the water or through the jersey
    • 2 choices of absorbent colors:
      • White: if you like to track your menstrual flow visually.
      • Black: for greater ease of maintenance.

Menstrual protection for swimming with or without menstrual cup

Every woman likes to enjoy the water or the sun for a long time, the swimsuit also provides for the blow thanks to press studs* located on the inside. It is therefore possible to change the absorbent during the day. Attach to it:

  • an insert
    • included with the jersey, both inside a super practical waterproof pouch for transport
    • made from the same absorbent fabric used for the gusset lining
    • interchangeable as many times as you want throughout your menstrual flow.

* Rest assured, the snaps are:

  • super thin (so you never feel or see them through the shirt)
  • plastic (to avoid rusting due to humidity)

À rendu le sourire à ma fille

Ce maillot à servit à ma fille de 12 ans qui est encore mal à l'aise à faire fasse à ces règles et elle avait une journée de glissade d'eau, ce maillot lui a permis de participer à sa sorti et d'être à l'aise. Les jeunes adolescentes qui ne sont pas à l'aise de mette des tampons ou pas prête. Ce maillot est une belle alternative. Merci énormément de lui avoir donner le sourire !
