Three materials for four thicknesses

Our menstrual lingerie is composed of the following layers, all free of metal nanoparticles:

1) Organic cotton, in contact with your skin

2) Absorbent fabric made from eucalyptus fibers (doubled for twice the absorption on our models for heavy, hemorrhagic flow)

3) A leak-proof PUL waterproof fabric

4) a second layer of organic cotton for the outside of your panties


Our organic cotton

Our organic cotton, entirely knitted and sewn in our workshop in France, is the only material that comes into contact with your skin!

This enables us to master maximum absorbency and breathability, guaranteeing you unrivalled comfort.

It is sometimes black, sometimes undyed for the inside of our panties, to limit stains, but can be colored for the outside of the lingerie.


Eucalyptus fiber

The protection zone is made of eucalyptus fiber, tencel.

It's a fiber made from cellulose extracted from the wood of this tree, with incredible absorption properties.



To prevent leaks, while our eucalyptus fiber fabric absorbs your blood, our PUL, the second layer of our protection zone, retains all liquids.

This waterproof yet breathable synthetic polyester material has your back.

Allergy-free plant fiber fabrics

Healthy for the planet, healthy for the body


The properties of organic cotton

Incomparably soft, you'll be surprised by how comfortable it is to slip on your lingerie.

A plant-based fiber, its naturally hypoallergenic properties are ideal for particularly sensitive people, as well as for prolonged contact with your intimacy in general.

With unrivalled durability and ease of maintenance, it has a long service life, making your switch to periods knickers worthwhile in the long term.

At Elia, we've combined it with a touch of elastane for added comfort (97% organic cotton and 3% elastane) and excellent elasticity to hug your shape.


Properties of eucalyptus fiber

This fabric has many properties: it feels fresh, neutralizes odors, absorbs moisture while remaining dry on the surface...

These are the qualities we look for in our menstrual lingerie.


PUL properties

Unbreakable and waterproof, our leak-proof PUL is resistant to repeated washing.

That's why this leakage-free material can be found in menstrual pants, cloth diapers, nursing pads, etc.


Eco-responsible eucalyptus fiber

The eucalyptus fiber we use in our menstrual lingerie technology is made in Austria, from wood grown in European forests.

The controlled process for preserving resources and the low level of irrigation required to grow eucalyptus make it a material with less impact on the environment.

That's why at Elia we've chosen to work with eucalyptus, rather than bamboo, which is often used in absorbent fabrics.

Bamboo, a victim of massive deforestation, did not reflect our values, and we wanted to offer you the most responsible products possible throughout the chain.

Our eco-responsibility


High-quality organic cotton

Our cotton is grown mainly in Turkey (renowned for its organic cotton). One of the advantages of organic cotton is that it requires much less water to produce.

France is also just beginning to produce organic cotton, and we're trying to source from our local market in the future, but volumes are currently insufficient. On the other hand, the weaving from this yarn is carried out entirely in France, in our workshops.

Like the rest of our materials, it is certified STANDARD 100 by OEKO-TEX®. This guarantees that our cotton is free of toxic products for the body and the environment. The use of organic cotton certifies the absence of pesticides in our knickers and a more responsible agriculture.
