Product description

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.

  • 0 swelling 
  • 0 odor

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.

Sustainability

Disposable pads, panty liners, and tampons are among the leading sources of plastic pollution worldwide.

During our reproductive years, we each use between 10,000 and 15,000 of these disposable products.

Sustainable alternatives like period underwear and period swimwear completely replace these disposables.
They help reduce the environmental impact of disposable products.

Care guide

Sorio reusable period products are washed in three simple steps:

1. Rinse in cold water until no more blood comes out. If there are stains, you can use a mild soap.

2. Machine wash on a delicate cycle (max 30°C / 86°F).

3. Air dry if possible.

Tip:
Don't use a dryer, fabric softener, or bleach. They would reduce effectiveness and shorten the product's life.

How does it work?

Video
  1. The honeycomb layer

    Keeps you feeling dry. This honeycomb layer lets blood pass through to the layers below. It is also hypoallergenic and antibacterial.

  2. The absorbent fabric

    A technical absorbent layer that captures and channels blood. Offers high absorption capacity.

  3. Flowlock™ reinforced waterproof membrane

    Keeps water and blood from mixing. This protection is leakproof.
    Blood stays trapped in the swimwear and water can't get in.

Customer Reviews

Overall rating: 4.7 / 5 from 350 reviews.

Nous avons connus sorio grâce à chatgpt ! en cherchant des maillots de bain très absorbant, il mettait sorio en tête. Et en allant sur le site on a lu les avis et on a commandé. Les produits sont de qualité, le service client est à l écoute. Nous avons rencontré énormément de difficultés avec Chronopost retard de colis, service client Chronopost incompétent. Par contre j ai eu l occasion d avoir une conseillère par rapport à tous nos soucis qui connaît très bien son travail. En ce qui concerne Chronopost vraiment il faut arrêter ! changer pour mondial relais Chronopost ne sont pas fiable du tout. Lors de notre commande on a eu un soucis de taille la conseillère nous a aidé pour l échange, vraiment bravo à Sorio.

Eva - Bas de maillot de bain menstruel ado pour flux abondant | Sorio®

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.

Frequently asked questions

What size should I choose?

Choose your usual swimwear size.

The size guide is just above the size selector, with exact measurements for each style.

How much can it absorb?

Our swimwear absorbs the equivalent of 3 to 4 tampons, depending on the absorption level you choose, and protects you for 8 hours.

And if you don't know your flow, our calculation guide helps you figure it out in one cycle.

Does it absorb water and balloon in the pool?

No. That's the key difference from regular period underwear.

The waterproof layer forms a barrier between blood and the water outside: flow stays inside, water stays out. The crotch doesn't balloon or get heavy, even after a long swim.

Can people tell it's period swimwear?

No. The absorption technology is built into the fabric and is only a few millimeters thick.

No diaper effect, no visible bulk: from the outside, it looks like any other swimwear.

How do I care for it?

Rinse it in cold water after each use until the water runs clear, then machine wash it at 30°C (86°F) max, in a laundry bag.

No dryer, no fabric softener, no iron: they would damage the absorption technology. Air dry. Everything is explained in our care guide.

How long does it last?

Several years with proper care. The fabrics are anti-chlorine and UV-protective to stand up to both the pool and the sun.

We recommend having at least two, so you can rotate them and let each one dry completely.

What are the shipping times and return terms?

Orders placed before 12 p.m. ship the same business day. Free shipping on orders over €49.

You have 100 days to change your mind. You can request a return from this page.
