Why choose menstrual underwear from Flow?
After two fertility treatments and two births, I no longer wanted to use menstrual products that had to be inserted into the body - I wanted to bleed in peace.
That was the beginning of Flow - the first period underwear on the Danish market.
Today, we create period underwear with a focus on comfort, quality, and responsible production - made 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 inconvenient - without compromising on style or function.
Best regards, Cathrine

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.
