The Manon menstrual swimsuit from Louloucup rises to the challenge of holding in your menstrual flow and locking it away. Once you’re in the water, the swimsuit stays put and your flow is contained. Absorbent on the inside and waterproof on the outside, the Louloucup Manon menstrual swimsuit lets you swim on your period with total peace of mind, without worrying about leaks or stains.

The plain black Manon menstrual swimsuit bottom has a very classic cut, no frills, no fuss, that goes with absolutely everything! For an on-trend mix-and-match look, the Manon swim brief is perfect. It can be paired with any colourful or printed bikini top. 

These period swim bottoms are extremely discreet and thin. No one will guess you’re wearing a menstrual bikini. The absorbent layer or pad that holds the blood does not swell up in contact with water. Even though the absorbent area extends across the front and back of the brief, it remains invisible. 

The Manon style absorbs the equivalent of two tampons. It’s therefore an ideal menstrual swimsuit for managing light to medium flows. For heavy flows, we recommend wearing a menstrual cup in addition to the swimsuit to guarantee zero leaks. 

The Manon menstrual swimsuit is available from size XXS to XL. It’s therefore suitable for even very petite teens who want durable, comfortable and washable period protection for their holidays! Check our size guide before ordering.

Want to try reliable, eco-friendly, zero-waste protection that’s kind to your body? Fed up with disposable tampons that are polluting and drying? Try the Manon menstrual swimsuit for your next dip in the water

And don’t forget, the Manon menstrual bikini bottom can be bought as part of a bundle with other panties, swimsuits or a cup so you can save even more! Keep it in mind when placing your order.


The Manon menstrual bikini bottom is made in China. The sewing workshop is audited for its limited use of plastic. This facility holds several ISO 9001 and BSCI certifications. The fabrics used to make the swimsuits are FDA approved.

How is our menstrual swimsuit so effective?

Our Louloucup swimsuits feature a hygienic pad specially designed for water use. This pad absorbs menstrual flow even in water. It absolutely does not swell on contact with water. Despite its very high absorbency, it remains thin and invisible. No diaper effect, we guarantee it—you’ll be comfortable! No one can tell the difference between our period swimsuit and a regular swimsuit. 

The period swimsuit lets you go to the beach with total peace of mind without needing an internal product like a tampon, menstrual cup, or pad. No need to worry about possible leaks. You’re completely free to move! 

Retrouvez votre liberté pour tout l’été !

Session baignade à la mer, à la piscine, farniente au soleil, prenez plaisir à rester en maillot pendant vos règles !
Nage et bronzette sont possibles en toute liberté sans angoisse ni crainte. Aussi bien dans l’eau que sur votre serviette de plage, vous êtes entièrement libre de vos mouvements. Si vous connaissez un flux léger à moyen, vous n’avez pas à utiliser de protection interne en supplément comme un tampon, une coupe menstruelle ou une serviette hygiénique.

Just like with regular swimsuits, Louloucup advises you not to keep your wet swimsuit on for too long after swimming. Moisture can more easily lead to yeast infections or urinary tract infections, so be careful!

Caring for your Manon menstrual swimsuit

Rinse the Manon menstrual swimsuit with clear water once you’ve taken it off. Remove the menstrual flow captured by the swimsuit’s absorbent layer by rinsing and gently wringing out the bottoms. Then pop it in the washing machine with the rest of your clothes. Choose a short cycle at 30°C and always let it air dry.
