HOW DO PERIOD PANTS WORK?
HOW DO PERIOD PANTS WORK?Flow period panties are sewn with a built-in pad, consisting of at least 3 technical layers, which draw fluid into the pad, absorb the fluid, and ensure that you do not bleed or leak through.
Absorption is approximately equivalent to:
Light flow: 2-5 mL
Moderate flow: 5-10 mL
Heavy flow: 10-15 mL

Why choose period underwear 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 beginning of Flow – the first period panties on the Danish market.
Today, we make period panties with a focus on comfort, quality, and responsible production – created by people who menstruate themselves.
✔️ Soft, skin-friendly materials
✔️ Different absorbency levels
✔️ Comfort like regular underwear
✔️ A more environmentally friendly alternative to disposable products
Our mission is to make menstruation more free, secure, and less bothersome – without compromising on style or function.
Best regards, Cathrine

THE HEART ALWAYS FIRST
We are also here to create bigger changes than just in your daily life.
Our founder changed Danish legislation in 2021 by removing the age limit on frozen eggs.
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 will continue.
PEACE OF MIND AND SAFETY 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 panties for chemicals and use innovation without compromising your safety to address odour 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 PEOPLE WHO MENSTRUATE, FOR PEOPLE WHO MENSTRUATE
We create products we ourselves need - and 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 just menstruation. It's about a body in change – 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 the entire cycle.
That's Flow Cycle Routine.

Frequently asked questions about menstrual panties
Det kan komme an på materialerne, din trusse er lavet af.
Mesh er meget stretchy og ligger du imellem to størrelser, så vil vi foreslå at size ned.
Lyocell og økologisk bomuld er lidt mere faste materialer, og her vil vi foreslå, at du tager din normale størrelse.
Det kommer an på trussens sugeevne, som står indikeret med dråber. Vi har menstruationstrusser til både moderat og kraftig blødning.
Bløder du meget kraftigt, så kan du med fordel bruge dine trusser sammen med en menstruationskop eller -disk.
Vi har også absorbernede trusser med lav absorbering til hverdagsbrug.
👉Har du brug for mere absorbering, så kan du vælge menstruationstrusser i stedet.
I trussens bund er et diskret bind af stof syet ind.
Uanset style består bindet af minimum 3 absorberende lag - et toplag, som leder væsken ned i det næste lag, som er minder om et håndklæde. Nederst finder du en membran, som sikrer at væsken ikke går gennem trussen.

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.
Tip: You can wash with our Allergy Certified special detergent Bloody Clean .
3. Dry them inside out on a clothesline - and you're good to go again.

Hvis du går fuldt ind på absorberende trusser og erstatter alle trusseindlæg og bind, så vil du have behov for 10-12 par - afhængigt af hvor let adgang du har til en vaskemaskine.
Men bruger du kun absorberende trusser kun til din menstruation, så foreslår vi 5-7 par.
Jo flere trusser, jo nemmere hverdag.
Derfor giver vi også bundlerabatter på flere par.
"Lækage" er egentlig ikke et ord, vi synes er så lækkert i sammenhæng med kroppen.
Det lyder mere som en utæt motor.
Men du bløder ikke direkte igennem dine trusser. Hvis de har nået deres 'max' på kapaciteten, så bløder du ud til siderne.
Det kan du tro, de er!
Forbrugerrådet Tænk har sat et stort fokus på menstruationstrusser i 2022, og deres eksperter siger også god for metoden:
1) Skyld i koldt vand.
2) Vask ved 40 grader.
3) Lufttør på snor.
