Flow - since 2021
Absorbent underwear for your postpartum
While the world may expect you to quickly ✨ bounce back ✨, we know that nothing is the same.
The body has given birth to a child. It bleeds. It leaks milk. It heals.
And in the middle of it all, you land – slowly – in a new version of yourself.
We celebrate the mess, the milk, the mucus, and the magic. Your postpartum flow.
At Flow you will find absorbent panties for postpartum bleeding and soft, wire-free nursing bras with built-in absorption – designed to give you security during a time when the body is working under high pressure.

We deserve better
For every little leak
The fourth trimester <3 Not only do we build an entire human (sometimes more). We also grow a whole new organ to perform the task. The placenta. And almost *overnight* from the moment we give birth to the placenta, the biggest hormonal crash the human body can experience occurs. The high levels of estrogen and progesterone, among others, from during pregnancy plummet.
It's a massive shift for the body, a greater drop and change in our hormones than puberty, PMS, and menopause - combined.
Let that sink in.
It deserves care and attention - and safe products.

THE HEART ALWAYS COMES FIRST
We are also here to create greater 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 secured the Danish women's national handball team the right to wear dark shorts during the World Cup. And we will continue.
PEACE OF MIND AND SECURITY IMMEDIATELY AFTER
Despite the lack of legislation and safety requirements for menstrual products in the EU, we do not hesitate to take our responsibility seriously. We do not use PFAS, nanosilver – no magical "stay fresh" treatments of the absorbent layers. We third-party test our underwear for chemicals and use innovation without compromising your safety to address odor issues.
PREMIUM PRODUCTION
We produce in Portugal, Denmark, Lithuania, and Turkey – always using the best materials such as organic cotton, organic merino wool, and ECONYL®.
Our partners are the best in their respective fields, and several of our factories are GOTS-certified, which sets requirements for employee care.
BY PEOPLE WHO MENSTRUATE, FOR PEOPLE WHO MENSTRUATE
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.
MORE THAN MENSTRUATION
We know. It’s about much more than just menstruation. It’s about a changing body - throughout the entire cycle, month after month.
That's why we're redefining what 'period products' are beyond a practical solution. The best-rated absorbent underwear, sure, 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.
Hier finden Sie Unser Leitfaden zur optimalen Pflege Ihrer Menstruationsunterwäsche.
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?
Das hängt von Ihrer Menstruationsstärke und Ihrem Zyklustag ab – sowie von der Saugfähigkeit der Unterwäsche.
Aber es gehört zur guten Hygiene, die Menstruationsunterwäsche mindestens morgens und abends zu wechseln – betrachten Sie Ihre saugfähige Unterwäsche genauso wie Binden und Tampons. Sie muss regelmäßig gewechselt werden.
Anders als beispielsweise bei Tampons besteht bei Menstruationsunterwäsche keine Gefahr des toxischen Schocksyndroms, da es sich um ein nicht-invasives Menstruationsprodukt handelt.
