Description of Menstrual Swimwear

You have irregular or heavy periods, but you too want to swim without thinking about it. 

Thanks to the enhanced absorbent technology (designed to handle your heavy flow) built into the Eva style, you can enjoy the water and the sun all day long. 

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. 

Period swimwear designed for heavy flows. 

The benefits of the Eva period swim bottoms for heavy flow: 

  • 0 swelling 
  • 0 odor 
  • 0 leaks
  • 0 stains
  • 8h of absorption

For optimal protection, choose your usual swimsuit size. 

Check the size guide to make sure the swimsuit fits properly, neither too loose nor too tight.  

With its versatile cut, it pairs easily with all your swim tops. 

The Eva heavy flow period swim bottoms are sold separately. 

You can also buy the Lya bikini top, matching the bottoms.

Molto resistente anche con flusso abbondante! Lo consiglio vivamente! 👍🥰

Superbe protection, taille bien et super confortable

Au top, fonctionne parfaitement. Permets d'oublier ses règles à la piscine. Je recommande car cela change la vie 😀

Merci pour votre gentillesse et votre compréhension

Tutto bene ci piace il prodotto arrivato in tempi brevi,bravi.

Ero scettica e invece... Mi ha salvato la vacanza!

Très bon maillot menstruel

J’adore

Très bon produits Tout de suite adopté

Ma fille est très satisfaite de son bas de maillot et peut enfin profiter de la plage et de la piscine sereinement.

Très contente et satisfaite de mon achat ! Je l'ai porté durant une après midi entière en alternant bronzage, baignade et balade, je n'ai eu aucune fuite. Ayant un flux plutôt abondant je vous le recommande a 100 %.

Mi trovo bene

Non ho ancora potuto usarlo, ma è veramente bello, ottima qualità. Sembra proprio un costume normale. Anzi, più bello.

Super.

Love it! My teenage daughter used it to bath in the sea during our holidays. It saved her day as she was feeling unlucky to get her period, this bikini really saved her day 🙌

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.

Super maillot, conforme en tout point au descriptif et photos, confortable et discret !! Service client très efficace et très réactif !!

Très satisfaite, aucune fuite très bonne absorption pour flux abondant et très confortable a mettre.j’adore 😍

Très bon produit.

Maillot de qualité pas encore essayé, il.faut être dans la bonne periode pour cela. Prendre une taille de plus, car taille petit. Peut-être revoir les tailles pour éviter toute surprise et le stress du retour

👌

Excelente, lo compré para mí hija ya que sabía que tendría su regla en vacaciones y ha sido todo un acierto, ahora cuando vuelva de vacaciones seguramente compraré bañador para sus clases de piscina en la escuela, super recomendable

Comodo

Parfait

Comodo e pratico Usato al mare , veramente utile

Parfait

Nessuno direbbe che è un costume mestruale! Lo adoro!😍

Corrisponde esattamente alla taglia che porto! Meraviglioso!

Ma fille adore. Elle est restée toute une journée dans la piscine a surveiller des enfants sans aucune fuite. Maillot top et service clients tout aussi top.

Ottimo prodotto!Super soddisfatta!

Très bien et reçu rapidement

Taille parfaite très confortable et on ne voit pas que c’est un maillot pour les règles

Livraison très rapide , commandé le mercredi et reçu ! Très belle qualité , pas encore tester dans l’eau ☀️

Super!!!!

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.
