Details
This summer, don’t let your period stop you from swimming!
Discover Néréides, our leak-proof menstrual swimsuit that can be worn without any additional protection throughout your cycle.
Thanks to its unique technology combining a snug fit, silicone anti-leak seals, and our signature menstrual membrane, our menstrual swimsuits are fully waterproof and offer real absorption (equivalent to 2 regular tampons) for up to 12 hours.
0 blood dispersion in the water,
0 swelling when wet,
0 stains on your towel.
With its perfect V-neckline, adjustable straps (that can be crossed or not), and flattering waistline, the Néréides swimsuit beautifully enhances your silhouette.
⚠️ For full effectiveness, this swimsuit should fit snugly. We recommend taking your measurements and checking our size guide.
If in doubt, feel free to contact our customer service at contact@smoon-lingerie.com.
For teens, we recommend taking measurements rather than choosing based on age or clothing size.
Made from materials resistant to saltwater and chlorine.
Provides UV protection (UPF 50+).
