Menstrual swim briefs, bikinis, and one-piece swimsuits

At Moi et Marie, you’ll find menstrual swimsuits in various styles, so there’s always a model that matches your preferences and body shape. Our menstrual swim briefs come in high or low waist: from discreet and sporty to more elegant and flattering designs.

Prefer a bit more coverage? In that case, a one-piece menstrual swimsuit is a comfortable and stylish choice that offers extra security. For those who like to mix and match, we also offer menstrual bikini pieces so you can create your own set.

Each model is made with the same reliable absorbent technology and a water-repellent outer layer. So you get the same level of protection and peace of mind, whether you choose briefs, a bikini, or a one-piece.

Freedom, comfort, and security—even in the water

Every woman and every body is different. That’s why Moi et Marie’s menstrual swimsuits are designed to offer you maximum freedom of movement without fear of leaks or discomfort. The absorbent layer inside the swimsuit holds menstrual flow or light incontinence, while the water-repellent outer layer prevents leaks, even in the water.

This way, you can keep doing what you want without tampons or pads. These swimsuits are perfect for teenagers experiencing their first periods, women who prefer to avoid disposable products, and those who want to stay active during their menstruation.

How does a menstrual swimsuit work?

Our menstrual briefs and swimsuits use smart multi-layer technology. The inner layer is made of an absorbent mesh that holds liquid and helps prevent odors. Beneath that is a water-repellent PU layer that stops liquid from escaping, even while swimming. The outer layer is soft, quick-drying, and pleasant against the skin.

The fit is just as important as the technology. The fabric fits well around the thighs and crotch to ensure effective leak protection—whether you’re swimming, diving, or just relaxing on your towel.

Durable, stylish, and consciously designed

At Moi et Marie, we believe comfort and sustainability go hand in hand. In spring 2022, we launched our own collection of menstrual panties and menstrual swimsuits, developed based on valuable feedback from our customers. We chose sustainable materials like bamboo and organic cotton—fabrics that are not only soft and comfortable but also highly absorbent.

Our menstrual swimsuits are made from PFAS-free, skin-friendly materials tested for safety and quality. This way, you choose a practical, reusable solution that lasts for several years. The fabrics are Oeko-Tex certified and ethically produced, so you can enjoy your time in the water with complete peace of mind.

Frequently asked questions about menstrual swimsuits

Can you really swim during heavy periods?

On average between two and four hours, depending on your flow. You might want to bring a spare bottom if you’re out for a long time.

Rinse it in cold water after use, wash at 30–40 °C without fabric softener, and let it air dry. This way, the fabrics maintain their absorbency and your swimsuit lasts longer.
