Description of Period Swimwear

Why teens love the Nina seamless period swim bottom


Nina is the seamless swim bottom that feels like a second skin!

Effective absorption: designed for light to moderate flow, Nina holds up to 2 to 3 tampons' worth of protection

  • No tampon, no leaks: your teen is protected throughout the swim without any extra protection
  • Adapts to her shape: fits all teenage body types without digging in, for maximum comfort
  • Modern cut: easy to pair with any swim top
  • Ultra-thin fabric: seamless construction feels like wearing nothing
  • Fully discreet: absorbent layer stays invisible and doesn’t swell in water
  • Chlorine & UV-resistant treatment: for a longer-lasting swim bottom

How does absorption work in Sorio period 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

Absorbent fabric made from natural bamboo fiber. 

This absorbent layer captures and channels blood. Its absorbency is equivalent to 3 tampons.

Layer 4

The waterproof outer fabric. 

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

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

In addition, it is chlorine-resistant and UV-resistant for longer-lasting wear.
