Menstruationsunterwäsche für mittlere Blutungen
We deserve better
Why choose menstrual underwear from Flow?
After two fertility treatments and two births, I no longer wanted to use menstrual products that went inside the body - I wanted to be able to bleed in peace.
That was the beginning of Flow - the first menstrual underwear on the Danish market.
Today, we make menstrual underwear focusing on comfort, quality, and responsible production - created by people who menstruate themselves.
✔️ Soft, skin-friendly materials
✔️ Different absorption levels
✔️ Comfort like regular underwear
✔️ A more environmentally friendly alternative to disposable products
Our mission is to make menstruation more free, secure, and less bothersome — without compromising on style or function.
Best regards, Cathrine

5 good reasons why you'll love us
THE HEART ALWAYS COMES FIRST
We're also here to make bigger changes than just in your everyday life.
Our founder changed Danish legislation in 2021 by having the age limit on frozen eggs removed.
In 2025, we created the Red Flag campaign, which ensured the Danish women's national handball team the right to wear dark shorts during the World Cup. And we're not stopping there.
SAFETY AND SECURITY IMMEDIATELY AFTER
Despite the lack of legislation and safety requirements for menstrual products in the EU, we do not hesitate to take responsibility. We do not use PFAS, nanosilver - no magical "stay fresh" treatments of the absorbent layers. We third-party test our period underwear for chemicals and use innovation without compromising your safety to solve odour problems.
PREMIUM PRODUCTION
Wir produzieren in Portugal, Dänemark, Litauen und der Türkei – und zwar immer mit den besten Materialien wie Bio-Baumwolle, Bio-Merinowolle und ECONYL®.
Unsere Partner sind die Besten in ihren jeweiligen Bereichen und mehrere unserer Fabriken sind GOTS-zertifiziert, was hohe Anforderungen an die Mitarbeiterfürsorge stellt.
BY THE MENSTRUATING FOR THE MENSTRUATING
We create products that we ourselves need - and we test them thoroughly (so yes, they have been tested with real menstrual blood). In addition, we have a test panel consisting of hardcore and dedicated members from our community who take the task seriously.
MEIN ENDE DER MENSTRUATION
We know. It's about much more than menstruation. It's about a changing body – throughout the entire cycle, month after month.
That's why we are redefining what 'period products' are beyond a practical solution. The best-rated absorbent underwear, yes, but also care that supports you and your body throughout your entire cycle.
That's Flow Cycle Routine.
FAQ
How long do period panties last?
Die durchschnittliche Lebensdauer von Socken und Unterwäsche beträgt etwa 3 Jahre. Es handelt sich um Kleidungsstücke, die täglich getragen und benutzt werden.
Da wir dem Verband keine chemische Behandlung zuführen, geht keine Funktion verloren.
Wenn Sie Ihre Slips gut pflegen und sie gemäß den Anweisungen waschen, ist die Qualität Ihrer Menstruationsslips von uns so gut, dass Sie sie problemlos 3 Jahre oder sogar länger verwenden können.

Wie finde ich das passende Produkt für mich?
We have menstrual panties that fit different bodies - whether you prefer a low rise, mid rise or high rise fit.
The Period Flow Brief and Period Flow Shorts both have a high waist, which is loved by many for the feeling of a hug around the belly.
Period Flow Cheeky has a more sporty look but with a wide and soft elastic at the waist - it is mid-rise.
Then we also have the classic low-waisted fit , which is a super nice, basic menstrual panty if discretion under the panty hem is *your thing*.
How long can I use them at a time?
It depends on your flow and your cycle day - as well as the absorbency of the panties.
But changing your menstrual panties at least morning and night is good hygiene - think of your absorbent underwear just like pads and tampons. They need to be changed every now and then.
But unlike tampons, for example, you are not at risk of Toxic Shock Syndrome, as menstrual panties are a non-invasive menstrual product.
