How does it work? period underwear
How does it work? period underwearFlow period panties are sewn with a built-in pad, consisting of at least 3 technical layers, which direct liquid into the pad, absorb the liquid, and ensure that you don't bleed or leak through.
Absorption is approximately equivalent to:
Light flow: 2-5 mL
Moderate flow: 5-10 mL
Heavy flow: 10-15 mL

That's why I started Flow
We deserve better
After 2 fertility treatments, fortunately resulting in two births, it only took three months for my period to return. And even though it was practically the same, I had changed. I no longer wanted to use menstrual products that went inside my body – I wanted to "bleed in peace."
I was the first to launch period underwear in Denmark. And today, I am proud of how far we have come – without compromising on ourselves, quality, or production. We deserve better menstrual products.
Sincerely, Cathrine

THE HEART ALWAYS COMES FIRST
We are also here to create bigger changes than just in your daily 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 still going.
SAFETY AND SECURITY IMMEDIATELY AFTER
Despite a 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 period underwear for chemicals and use innovation without compromising your safety to address odours.
PREMIUM PRODUCTION
We produce in Portugal, Denmark, Lithuania, and Turkey – and 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 standards for employee welfare.
BY THOSE WHO MENSTRUATE, FOR THOSE 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. It's about much more than 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 just a practical solution. The highest-rated absorbent underwear, yes, but also care that supports you and your body throughout your entire cycle.
That is the Flow Cycle Routine.

Frequently asked questions about menstrual panties
It may depend on the materials your panties are made of.
Mesh is very stretchy and if you are between two sizes, we would suggest sizing down.
Lyocell and organic cotton are slightly firmer materials, and here we would suggest that you take your normal size.
It depends on the absorbency of the panties, which is indicated by drops. We have menstrual panties for both moderate and heavy bleeding.
If you are bleeding very heavily, you can use your panties together with a menstrual cup or disc.
We also have absorbent panties with low absorbency for everyday use.
👉 If you need more absorption, you can choose menstrual panties instead.
A discreet fabric band is sewn into the bottom of the panties.
Regardless of the style, the pad consists of a minimum of 3 absorbent layers - a top layer that conducts the liquid down into the next layer, which is similar to a towel. At the bottom you will find a membrane that ensures that the liquid does not pass through the panty.

Rinse - wash - wear - repeat
1. If you have spotting in your panties, rinse them in cold water until the water runs clear.
2. Protect your panties in a laundry bag and wash your panties with similar colors at 30-30 degrees.

If you go all-in on absorbent panties and replace all panty liners and pads, you will need 10-12 pairs - depending on how easy you have access to a washing machine.
But if you only use absorbent panties for your period, we suggest 5-7 pairs.
The more panties, the easier everyday life.
That's why we also offer bundle discounts on multiple pairs.
"Leak" isn't really a word we find so delicious in the context of the body.
It sounds more like a leaking engine.
But you don't bleed directly through your panties. If they have reached their 'max' capacity, you bleed out to the sides.
You can believe they are!
The Danish Consumer Council Think has put a big focus on menstrual panties in 2022, and their experts also say good things about the method:
1) Rinse in cold water.
2) Wash at 40 degrees.
3) Air dry on a line.
