Need to do laundry during your holiday?
In 2026, Flow will relaunch period swimwear
How does period swimwear work?
Our period swimwear is designed with:
〰️ A soft layer close to the body that directs fluid down into the next layer
〰️ An absorbent core that stops bleeding
〰️ A water-repellent, breathable membrane that minimizes the risk of bleeding through
The material dries quickly and feels light – even after a trip in the water.
