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

FAQ
How long do period panties last?
The general expectation for the lifespan of socks and underwear is approximately 3 years. These are items of clothing that are worn out and used every day.
Since we do not add chemical treatment to the pad, no function will be lost.
If you take good care of your period pants and wash them according to the instructions, the quality of our period pants is so good that you can easily use them for 3 years or even longer.
Here you will find our guide on how to best care for your period pants.
How do I choose the best fit for me?
We have menstrual panties that fit different bodies - whether you prefer a low rise, mid rise or high rise fit.
The Period Flow Brief and Period Flow Shorts both have a high waist, which is loved by many for the feeling of a hug around the belly.
Period Flow Cheeky has a more sporty look but with a wide and soft elastic at the waist - it is mid-rise.
Then we also have the classic low-waisted fit , which is a super nice, basic menstrual panty if discretion under the panty hem is *your thing*.
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.
