FAQ

Should I wear a tampon or a menstrual cup with this swimsuit?

keyboard_arrow_down
add remove

Because every body and every cycle is unique, your needs evolve throughout your period and your days.

To get used to your period swimsuit with complete peace of mind and understand how it reacts to your own flow, we recommend doing an initial test at home. Wear it quietly in the bath, in the shower, or during a session in your bathtub/pool before heading out in public. It’s the ideal way to evaluate your comfort and identify your ideal level of protection!

During light to medium flow days: our swimsuit is entirely sufficient on its own, offering you total freedom without any unnecessary extra protection.

During heavier flow days: you can pair it with additional protection (tampon, cup) to guarantee a swim with 100% peace of mind and zero stress.

How long can I wear my jersey without changing it?

Our swimsuit bottoms effectively absorb your flow for 5 hours up to 35ml (equivalent to 3 to 4 tampons). For optimal comfort, having a second swimsuit on hand to stay dry is the best!

The time it takes for your swimsuit to reach its maximum absorption varies from person to person and depends on everyone's period. To better understand the absorption and leak-proof protection of our products in relation to your flow, we recommend testing your Naia Swim purchase at home, in and out of the pool or shower/bath, to determine what works best for you.

What happens when I go swimming?

Each swimsuit features three layers that trap and absorb blood and discharge while you swim. The bottom layer of the swimsuit features a waterproof membrane that prevents water from entering the swimsuit.

To better understand the absorption and leak-proof protection of our products in relation to your flow, we recommend testing your Naia Swim purchase at home, in and out of the pool or shower/bath, to determine what works best for you.

Can I swim, move around, and exercise?

Our bikinis are designed to follow you in all your movements, at the beach or in the water. Comfortable and well-fitted, they allow you to enjoy swimming and moving with complete freedom.

Has the technology been tested?

add remove

We can say with confidence that yes!

All our fabrics come from factories that manufacture using environmentally friendly processes, without the use of toxic chemicals or solvents.

All products have been tested under real-life conditions by our founder Salomé and a team of testers!

How do I wash it?

After each use, rinse your swimsuit in cold water to remove excess flow. You can then machine wash it at 30°C, without fabric softener to preserve the effectiveness of the absorbent layers. Let it air dry, preferably flat, so it keeps its shape (avoid the tumble dryer).
