Washing guide
Washing guideUse them, rinse them in cold water and wash them at 30 or 40 degrees with the rest of your clothes.
The detergents we have today are super effective, so you can easily wash the panties clean at low temperatures.
Avoid drying in the tumble dryer! It is not good for the environment and the absorbent layer will lose its absorbency more quickly
How does it work
How does it work Flow menstrual panties are sewn with a built-in pad, consisting of a minimum of 3 technical layers, which direct fluid into the pad, absorb the fluid and ensure that you do not bleed or leak through.

Derfor startede jeg Flow
Vi fortjener bedre
Efter 2 x fertilitetsforløb og heldigvis også to fødsler, så gik der kun tre måneder før min menstruation var tilbage. Og selv om den i praksis var den samme - så var jeg forandret. Jeg havde ikke længere lyst til at bruge menstruationsprodukter, der skulle ind i kroppen - jeg havde lyst til at "bløde i fred".
Jeg var den første til at lancere menstruationstrusser i Danmark. Og i dag er jeg stolt af, hvor langt vi er kommet - helt uden at gå på kompromis med os selv, kvalitet eller produktion. Vi fortjener bedre menstruationsprodukter.
Kærlig hilsen Cathrine

HJERTET ER ALTID FØRST
Vi er her også for at skabe større forandringer end blot i din hverdag.
Vores founder har ændret dansk lovgivning i 2021 ved at få fjernet aldersgrænsen på nedfrosne æg.
I 2025 skabte vi kampagnen Rødt Flag, som sikrede det danske kvindelandshold i håndbold retten til at bære mørke shorts under VM. Og vi bliver ved.
TRYGHED OG SIKKERHED LIGE EFTER
Til trods for manglende lovgivning og sikkerhedskrav til menstruationsprodukter i EU, så tøver vi ikke med vores ansvar. Vi bruger ikke PFAS, nanosølv - ingen magiske "stay fresh"-behandlinger af de absorberende lag. Vi tredjepartstester vores trusser for kemi og bruger innovation uden kompromis med din sikkerhed til at løse lugtgener.
PREMIUM PRODUKTION
Vi producerer i Portugal, Danmark, Litauen og Tyrkiet - og altid med de bedste materialer som fx økologisk bomuld, økologisk merinould og ECONYL®.
Vores partnere er de bedste indenfor hver deres felt og flere af vores fabrikker er GOTS-certificerede, som stiller krav til medarbejderpleje.
AF MENSTRUERENDE FOR MENSTRUERENDE
Vi skaber produkter, vi selv mangler - og tester dem grundigt (så ja, de er testet med rigtigt menstruationsblod). Dertil har vi et testpanel bestående af hardcore og dedikerede medlemmer fra vores community, der tager opgaven alvorligt.
MERE END MENSTRUATION
Vi ved det godt. Det handler om meget mere end menstruation. Det handler om krop i forandring - hele cyklus igennem, måned efter måned.
Derfor er vi ved at redefinere, hvad 'mens-produkter' er udover en praktisk løsning. Det bedst ratede absorberende undertøj jovist, men også pleje der støtter dig og din krop gennem hele cyklus.
Det er Flow Cycle Routine.

Most asked questions about period underwear
We recommend you to choose your normal size. We strive to continuously streamline the collection, although the materials may work slightly differently.
Make sure the panties fit relatively close to the hip, as they need to be able to hold the blood.
Remember; you can always exchange as long as you try your Flows with your own panties underneath.
Our panties have different absorbency, but this is described under each style, indicated by drops. We continue to work on expanding the range.
If you bleed heavily, you can use a menstrual cup or disc together with our menstrual panties.
The top layer at the bottom of the panty is woven so that the blood is directed down into the panty, and this keeps your skin dry.
The middle layer is woven like a towel so that it holds the blood (or other fluids, e.g. urine).
And at the bottom is a polyamide membrane that ensures that you don't bleed through.
After use, rinse them in cold water until the water runs fairly clear. The cold water breaks the surface tension of the blood, making it easier for the washing machine to get them clean. Then, wash at 40 degrees and air dry them inside out.
It depends both on how often you wash clothes - and how much you bleed.
The more you bleed, the more often you need to change your panties. Most people switch morning and evening - and with heavier bleeding, e.g. day 2-3, an extra time in the afternoon. Think of it as changing roughly as often as a pad.
On that level, a start could be 3 pairs (you always get 10% on 3-4 pairs). Then you can test how the day goes.
But the more pairs, the easier and more comfortable the experience. We have customers who have 10-12 pairs in their drawer. And you always get 15% on 5 pairs or more.
... Pssst... Your panties are suitable for "all bodily fluids; after sex, after a good laugh, during menstruation.
It's such a lame word, "leak". It sounds like an engine dripping.
We have a body that bleeds - sometimes the blood runs in unfathomable ways. Also next door.
But of course we understand the word. And yes, they are leak-proof, provided they are used for what they can handle.
If you experience 'leakage', you will experience bleeding to the sides rather than through, as the membrane will prevent permeation.
You will find the absorbency of each style on each product page.
You bet they are!
The Danish Consumer Council Tænk focused heavily on menstrual panties in 2022, and their experts also endorse the method:
- Rinse in cold water.
- Wash at 40 degrees.
- Air dry on a line.
Today's detergents are hyper-effective – and remember: We’re dealing with menstruation. It’s just blood.
Let me know if you need any changes!
The modern disposable pad first made its appearance in the 1960s. Before that, cloth pads were the most common option.
Period underwear is an evolution, so to speak, and a reusable product that is also extremely comfortable – you feel like you’re just wearing regular underwear. We have customers who say they sometimes forget they’re on their period.
