I bought the Alia shorty for my daughter, who has quite a heavy flow. She wore it during sports and felt well protected, without feeling restricted in her movements.

I got it for my teenage daughter, especially for the days when she has sports during her period. The shorty is comfortable, reassuring, and she feels confident moving without overthinking it.

My daughter was worried about leaks during sports, so we tried the Alia shorty. She quickly adopted it: it stays in place, feels discreet, and gives her much more peace of mind.

Ho avuto un problema con il precedente ordine che era andato smarrito. L'ufficio clienti è stato bravissimo e ha predisposto di nuovo la spedizione a proprio carico. Secondo ordine arrivato in tempi perfetti

Dommage pour le premier problème de livraison qui ne s’est pas bien passé… mais bon le service client a été compréhensif et efficace ensuite. Le produit est de bonne qualité. J’aurais aimé que le haut soit vendu avec.

Shorty de bain Menstruel flux abondant noir - Alia | Sorio®

Boxer de bain très agréable à porter. On n'y voit que du feu. Mes règles sont très abondantes et pour l'instant la petite baignade d'une demi heure que je me suis octroyée au 2e jour a été une réussite! Merci Sorio pour cette liberté retrouvée !

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.
