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 menstrual panties from Flow Intimates?
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 menstrual underwear on the Danish market.
Today, we make menstrual 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 more free, secure, and less bothersome - without compromising on style or function.
Best regards, Cathrine

THE HEART ALWAYS COMES FIRST
We are also here to create changes beyond your daily life.
Our founder changed Danish legislation in 2021 by having the age limit for 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 will continue.
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 for 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 – and always with 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 THE MENSTRUATING FOR THE MENSTRUATING
We create products we ourselves need – and test them thoroughly (so yes, they are tested with real menstrual blood). We also 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 body in change - 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, sure, but also care that supports you and your body throughout your 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.
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.
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.

Regular waist menstrual panty with extra long absorbent panel
Regular-waisted menstrual panties, also called Period Flow Cheeky, are designed for those who want regular-waisted menstrual panties, a sporty fit and extra protection on days when you need a little more security.
The mid-rise waist and high-cut leg give a light and flattering look, while the soft organic cotton makes the panties comfortable to wear all day.
Formerly known as Flow 3 – new name, same beloved model.
Extra bandage length. Extra security.
What makes Period Flow Cheeky so special is the extra long and reinforced absorbent panel.
In size Small, the panel measures the entire 37 cm and is 25% thicker than our standard panel – without the panty feeling thicker or heavier.
The extra length provides greater coverage, especially if you:
-
tends to bleed at the front
-
sleeping on stomach
-
find that regular volumes are too short
-
want extra security on heavier menstrual days
For moderate to heavy menstruation
Period Flow Cheeky is developed for moderate+ menstruation and provides extra security throughout the day and night.
If you have very heavy periods, you can combine the panties with a menstrual cup or menstrual disc on the heaviest bleeding days.
Like all our menstrual panties, Period Flow Cheeky has a discreet built-in absorbent panel, so it looks and feels like regular underwear.
Soft organic cotton with a sporty fit
The panties are sewn from soft organic cotton, which feels pleasant against the skin and provides natural, breathable comfort.
The mid-rise waist and high-cut leg give a modern, sporty look, while the fit follows the body's movements without being tight.
This makes Period Flow Cheeky a favorite among many who want a lighter silhouette than a high-waisted model – but still need extra protection.
