"The best briefs on the market"

We deserve better

Why choose Flow period underwear?

After two fertility treatments and two births, I no longer wanted to use menstrual products that went inside my body - I wanted to be able to bleed in peace.

That 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 absorption levels
✔️ Comfort like regular underwear
✔️ A more environmentally friendly alternative to disposable products

Our mission is to make menstruation freer, safer, and less complicated - without compromising on style or function.

Kind regards, Cathrine

Menstrual swimwear for teens

Can teens bathe during menstruation?

An Australian study shows that 67.3% of teens avoid swimming during their period. We want to change that.

Of course, you can bathe during your period - some will even experience relief from discomfort when moving in water.

Menstrual swimwear makes it possible to swim safely during menstruation - the same technical layer as in your panties, but quick-drying.

If you are bleeding heavily, a menstrual pad or cup can be a good supplement.
