Long overlooked in development aid priorities, menstrual hygiene began to be recognized in the 2010s as a fundamental right and has since received renewed attention.

Building on this recognition, the international solidarity sector is witnessing a rapid increase in demand for menstrual hygiene products. Yet this demand still lacks an adequate supply.

The sector’s specific requirements — product adaptability to diverse populations, performance in contexts with limited access to water and sanitation, and a balanced quality‑to‑cost ratio — remain unmet.

Innovating to offer a new product has become essential.

To design and manufacture reusable menstrual underwear covering women’s hygiene needs throughout their entire cycle, achieving the best balance between quality, durability, and price. More specifically:

Why a new product ?

The consumer market — highly heterogeneous in terms of quality and price — does not meet the aid sector’s need for a product that can be adjusted to a wide range of body sizes and menstrual flows.

It is also marked by a high level of opacity regarding the actual composition and absorption capacity of menstrual underwear, as well as by a significant environmental footprint linked to production locations.

The supply specifically targeting aid actors still largely consists, even today, of reusable sanitary pads.

This is despite the advantages offered by menstrual underwear in terms of comfort, discretion, and performance.

What we propose

A product adapted to a diversity of women (sizes and menstrual flows) and to contexts with limited access to water and sanitation.

With quality and durability guarantees certified by an independent laboratory.

Tested and approved both by users and partners, through a participatory and iterative approach.
