THE HEART ALWAYS COMES FIRST

We are also here to make bigger changes than just in your everyday life.
Our founder changed Danish legislation in 2021 by removing the age limit for frozen eggs.
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 of the absorbent layers. We third-party test our underwear for chemicals and use innovation without compromising your safety to eliminate odours.

PREMIUM PRODUCTION

We produce in Portugal, Denmark, Lithuania, and Turkey – always using the best materials such as organic cotton, organic merino wool, and ECONYL®.

Our partners are leaders in their respective fields, and several of our factories are GOTS-certified, which ensures high standards for employee welfare.

BY PEOPLE WHO MENSTRUATE, FOR PEOPLE WHO MENSTRUATE

We create products that we ourselves need - and we test them thoroughly (so yes, they are tested with real menstrual blood). In addition, we have a test panel consisting of hardcore and dedicated members from our community who take the task seriously.

MORE THAN MENSTRUATION

We know. It's about much more than just menstruation. It's about a changing body – throughout the entire cycle, month after month.

That's why we are redefining what 'period products' are beyond just a practical solution. The best-rated absorbent underwear, yes, but also care that supports you and your body throughout your entire cycle.
This is Flow Cycle Routine.

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 wear out and are used every day.

Since we do not add chemical treatment to the pad, no function is lost.

If you take good care of your period panties, washing them according to instructions, then the quality of our period panties is so good that you can easily use them for 3 years and even longer.

Here you can find our guide on how to best care for your period panties.

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.
