Period swimsuit - Jenny

Menstrual swimwear, like Flow menstrual panties, is sewn with a built-in pad, consisting of a minimum of 3 technical layers that direct fluid into the pad, absorb the fluid and ensure that you do not bleed or leak through.

Flow's founder
Relaunch of Period Swimwear 2026
"Period swimwear is back! We've spent two years perfecting the fit and materials (we've chosen the best Italian fabrics).
Last summer, I tested the function and fit. I'm not usually a water baby, but of course, the samples I had in my suitcase had to pass their big test.
They passed with flying colours. I felt safe, comfortable - and chic. I'm incredibly excited to see you in the swimwear on the beach, by the pool, in gardens".

Frequently asked questions
Please wear your regular size in your swimwear.
If you are between two sizes, we would suggest the smaller one, as the fabric can stretch when wet.
The absorbency of menstrual swimwear is light to moderate.
If you are bleeding heavily, we suggest that you combine it with a cup or a disk.
Our swimwear is designed with a built-in, absorbent layer that captures and encapsulates menstrual blood. This layer is combined with a waterproof yet breathable membrane that prevents you from bleeding through while swimming or sunbathing.
The textiles are light and quick-drying, ensuring that you can move freely and feel dry shortly after being in the water.
1. If you have bled in your menstrual swimwear, rinse them in cold water until it runs clear.

Jenny is designed with a specially designed absorbent gusset, which is integrated into the swimsuit. It is designed for light to moderate period and works by helping to collect menstrual blood when you are out of the water, while the tight-fitting layers provide extra security while bathing.
