Bras without underwire
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
What we are most proud of
5 good reasons why you'll love us
THE HEART ALWAYS COMES FIRST
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
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 welfare.
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.
MORE THAN 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.
FAQ
How long do period panties last?
The expected lifespan of socks and underwear in general is approximately 3 years. These are items of clothing that are subject to daily wear and tear.
Since we do not add chemical treatments to the pad, there is no function that degrades.
If you take good care of your period pants and wash them according to instructions, the quality of our period pants is so good that you can easily use them for 3 years or even longer.
Here you can 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.
Underwire bras - underwire bras provide comfort without compromise
Bras without underwire are the softest and rarest everyday choice. A good underwire bra should feel so comfortable that you almost forget you're wearing it.
At flow we design underwire bras with a focus on natural support, soft materials and well-thought-out details that follow the body – not the other way around. Our Everyday collection is created for everyday life, where comfort, freedom of movement and a simple, Scandinavian design go hand in hand.
Whether you prefer a classic cut or a feminine plunge model, you will find an underwire bra that supports without tightening.
Why choose a bra without an underwire?
Many choose a bra without an underwire because it gives a more natural feeling throughout the day.
Without metal underwires, you get greater freedom of movement and a bra that molds to the body. At the same time, our models are developed with wide elastics, well-thought-out cuts and adjustable straps, so you still get the support you need.
The result is a bra that is equally suitable for work, relaxation, homework and long days on the go.
Soft materials with high comfort
Our Everyday bras are sewn in soft and breathable lyocell, which feels comfortable against the skin all day.
The material is chosen for its soft quality, elegant fit and light comfort. Together with the underwire construction, it gives an experience of freedom without the bra losing its fit.
Find the model that suits you
In the collection you will find two different expressions:
Everyday Bra Scoop has a deeper cut and a more feminine look. It fits perfectly under shirts, dresses and V-neck tops - while providing natural support without underwire. The bra has adjustable straps and gathers under the bust for a beautiful cup and rounding of the bust.
Everyday Bra Plunge has a classic, round cut and provides a little more coverage. It is perfect for those who want a timeless look and maximum comfort.
Both models are designed to be used all day and can be matched with our Everyday flow Thong and Soft collection for a complete underwear set.
That's why women choose flow

Comfort for the whole day
