Menstrual swimsuit (One piece) - Fir tree

The Marie fil menstrual swimsuit looks like a regular swimsuit. The difference? It adapts to menstruation and becomes menstrual protection when needed. Every woman can always rely on it with her eyes closed.

One-piece menstrual swimsuit made in Quebec

Marie fil's one-piece menstrual swimsuit is entirely made in Quebec. It offers unique features:

• 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.

Swimming with light to heavy menstruation

The one-piece menstrual swimsuit adapts to the menstrual flow. It can be suitable for a light flow or be used in duo with the menstrual cup. In any case, this menstruation-friendly swimsuit alone is sufficient.

One-piece menstrual swimsuit with insert

For long days at the beach or the swimming pool, the one-piece menstrual swimsuit also provides for the blow thanks to press studs* located inside. If you want to be able to change the absorbent during the day, it is therefore possible to fix:

Insert for menstrual swimsuit

• • included with the jersey, both inside a super practical waterproof pouch for transport
  • made from the same absorbent fabric used for the gusset lining

* Rest assured, the snaps are:
