Details
This summer, your period won’t stop you from going for a swim!
Discover Néréides, our waterproof menstrual swimsuit that can be worn without any additional protection throughout your entire cycle.
Thanks to its unique technology combining a snug fit, silicone leak-proof seals, and our iconic menstrual membrane, our menstrual swimsuits are waterproof and provide real period absorption (equivalent to 4 regular tampons) for up to 12 hours.
No blood dispersion in the water,
No swelling once wet,
No stains on your towel.
With its perfect V-neckline, adjustable straps that can be crossed or not, and a redesigned waist, the Néréides swimsuit will enhance your silhouette.
⚠️ For full effectiveness, this swimsuit should be worn very snugly. We recommend taking your measurements and consulting our size guide.
If you have any doubts, don’t hesitate to contact our customer service by email at contact@smoon-lingerie.com.
