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.

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.
