Why choose menstrual panties from Flow?
After two fertility treatments and two births, I no longer wanted to use menstrual products that went inside the body – I wanted to be able to bleed in peace.
This was the beginning of Flow – the first period underwear on the Danish market.
Today, we make period underwear 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 eco-friendly alternative to disposable products
Our mission is to make menstruation more free, secure, and less inconvenient — without compromising on style or function.
Best regards, Cathrine
