• After studying different technical solutions, Decathlon decided to collaborate with Smoon , the French brand of technical menstrual underwear known for its unique anti-leak technology. ​

    ​The common goal?

    Allow women to play sports and swim in all circumstances.

    We therefore worked hand in hand for more than a year to develop the Thétys swimsuit:
    A one-piece menstrual swimsuit capable of not only absorbing periods but also containing them in a waterproof swimsuit.

    It can therefore be worn without additional protection for the entire duration of the cycle.

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

    My opinion on their period panties? Honestly, buy Smoon products with your eyes closed! Everything is perfect, the thong is seamless, super discreet, the size is perfect and fits well, the beige is perfect under white, the fabric is nice, no leaks, no stains, and it does not move around. machine wash at 30°!
    What more could you ask for, it's perfect!

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