The nice to know and need to know

What is menstrual swimwear?

Menstrual swimwear is swimwear with built-in absorbent technology that makes it possible to swim safely during menstruation with light to moderate bleeding.

You know our absorbent technology from our menstrual panties, which are added to the bottom of the swimsuit in a quick-drying quality.

Welchen Stil soll ich wählen?

We will launch a large swim collection in 2026, which will include both menstrual swimsuits and bikinis.

You can choose between different fits, colors and materials. Enjoy!

Was erhalten Sie im Kaufpreis?

Jedes Period Swim-Modell ist in einem kleinen, wiederverschließbaren Beutel verpackt, den Sie aufbewahren und unterwegs verwenden können, wenn Ihre Bademode nass ist.

Wir können Ihnen außerdem den Kauf von Bloody Clean empfehlen. Dabei handelt es sich um ein Spezialwaschmittel, das Ihre Badebekleidung besonders schonend reinigt und jegliche Gerüche entfernt.

Wir haben es auch in Reisegröße, Bloody Clean finden Sie hier →

First drop of the season: Jenny Swimsuit

News of 2026

Im Jahr 2026 wird Flow Menstruationsbademode neu auflegen.

How do menstrual swimwear work?

Our menstrual swimwear is designed with:

〰️ A soft layer close to the body that directs fluid down into the next layer

〰️ An absorbent core that stops bleeding

〰️ A water-repellent, breathable membrane that minimizes the risk of bleeding through

The material dries quickly and feels light – even after a trip in the water.

How do I wash my menstrual swimwear?

Before use: Wash your menstrual swimwear at 30-40 degrees before using it.

Step 2: Wet directly into your swimsuit when you have your period

Step 3: Rinse the pad in your menstrual swimsuit by hand after use until the water runs clear.

Step 4: Put the swimsuit in a laundry bag and wash with similar colors at 30-40 degrees and let it air dry inside out.

Mix and match to suit your needs

Swimsuit or bikini?

When we first launched menstrual swimwear on the Danish market in 2024, we only launched one bikini - it sold out before the summer was over.

Now we are expanding with more fits, materials and cuts:

〰️ Menstrual bikinis offer flexibility and the opportunity to mix and match.

〰️ Menstrual swimsuit provides extra coverage and support.

Both are designed to look like regular swimwear – no one can tell the difference.

We write women into history
