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.
Nursing bra with absorption
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?
The expected lifespan of socks and underwear in general is approximately 3 years. These are garments that are worn and used every day.
Since we do not apply chemical treatment to the pad, there is no function that deteriorates.
If you take good care of your period pants and wash them according to the instructions, the quality of our period pants is so good that you can easily use them for 3 years and even longer.
Here you will find our guide on how to best care for your period pants.
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.
Bøjlefri amme-BH med absorbering
En god amme-BH skal gøre hverdagen lidt lettere.
Hos Flow finder du bøjlefrie amme-BH'er med indbygget absorberende teknologi, udviklet til dig, der ønsker komfort, naturlig støtte og ekstra tryghed under amningen. Vores absorberende skåle hjælper med at opsamle mindre lækager af brystmælk og kan reducere behovet for løse ammeindlæg.
Samtidig er BH'erne designet til nem amning med et blødt crossover-design, så du hurtigt kan lægge dit barn til – uden spænder eller kliklåse.
En amme-BH, der arbejder med kroppen
Den første tid efter fødslen forandrer kroppen sig fra dag til dag.
Brysterne kan være ømme, følsomme og skifte størrelse i takt med mælkeproduktionen. Derfor har vi udviklet en bøjlefri amme-BH, som former sig efter kroppen og giver behagelig støtte uden at stramme.
Det bløde crossover-design gør det nemt at amme med én hånd, mens den brede elastik under brystet giver en naturlig støtte gennem hele dagen.
Indbygget absorbering mod brystlækage
Det særlige ved vores amme-BH er det diskrete absorberende lag, som er syet direkte ind i skålene.
Det hjælper med at opsamle mindre lækager af brystmælk og giver ekstra tryghed mellem amningerne. For nogle kan det betyde, at behovet for løse ammeindlæg bliver mindre, mens andre vælger at bruge BH'en som et ekstra lag beskyttelse.
Økologisk merinould mod huden
Indersiden af skålene er beklædt med økologisk merinould, som føles blød mod sensitive brystvorter.
Merinould er naturligt temperaturregulerende og åndbar, hvilket gør den særligt behagelig i den første tid efter fødslen, hvor huden ofte er ekstra følsom.
