Bügel-BHs – ohne Absorption

We deserve better
Why choose menstrual panties from Flow?
After two fertility treatments and two births, I no longer wanted to use menstrual products that went inside my body - I wanted to be able to bleed in peace.
That was the start of Flow - the first period underwear on the Danish market.
Today, we make period underwear with a focus 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 freer, safer, and less complicated - without compromising on style or function.
Best regards, Cathrine

DAS HERZ STEHT IMMER AN ERSTER STELLE
We're also here to create 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 shy away from our responsibility. We do not use PFAS, nano-silver - no magical "stay fresh" treatments of the absorbent layers. We third-party test our panties for chemicals and use innovation without compromising your safety to address odor issues.
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 PERIOD-HAVERS, FOR PERIOD-HAVERS
We create products that we ourselves need – and we test them thoroughly (so yes, they are 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 is Flow Cycle Routine.

How do I choose the best fit for me?
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.
