Super contente de mon achat

J'ai toujours eu des règles hémorragiques et la plage était une épreuve. J'ai testé et c'est révolutionnaire, j'ai tenu 6h sans aucune fuite. C'est la première fois en 15 ans que je me baigne l'esprit léger sans vérifier ma serviette toutes les 5 minutes.

J'avais peur que le bas devienne lourd ou que le sang s'échappe en sortant de l'eau à cause du flux important, pas du tout !!!

Acheté pour pouvoir rester toute la journée sur le bateau avec des amis. Pari réussi ! C'est confortable, on ne sent aucune humidité et ça change la vie de ne pas avoir à gérer de protections jetables dans des endroits compliqués. Un indispensable pour toutes celles qui ont des règles compliquées

The enhanced absorbency capacity of the Eva period swimsuit for heavy flow is equivalent to 5 tampons and gives you 8 hours of freedom. 

Even though the absorbency capacity of the Eva swimsuit is reinforced, it remains thin and very discreet so as not to create a bulky feel.

Overall rating: 4.7 / 5 from 342 reviews.

Maillot de bain de bonne qualité et beau, on ne voit pas que c'est un maillot de bain de règle. Légèrement serrée pour moi, mais j'ai peur que si je prends la taille au-dessus il soit trop grand. Il est discret, j'hâte de l'essayer en période de règle.

How does absorption work in Sorio menstrual swimwear?

Layer 1

A breathable hypoallergenic lining.  

The lining protects your intimate comfort by helping protect you from infections. 

Layer 2

A honeycomb layer. 

This honeycomb layer lets blood pass through to the lower layers to keep you dry all day long by avoiding contact between your skin and the blood.

Layer 3

The absorbent fabric made from natural bamboo fiber. 

This absorbent layer captures and channels the blood. Its absorption capacity is equivalent to 3 tampons.

Layer 4

The waterproof outer fabric. 

This final textile layer is the outer part of the menstrual bikini bottom. 

It prevents water from seeping into the swimsuit and therefore prevents any risk of leaks.  

In addition, it is treated to resist chlorine and UV rays for longer-lasting wear.
