OUR MISSION

At Tethys, we believe that thermal comfort is not a luxury, but an essential condition for worker safety, productivity, and dignity.

In a world where extreme temperatures are becoming the norm, our ambition is simple: to enable every professional to work in the best possible conditions, regardless of the environment.

“Safety and health at work are a fundamental right at work.” ILO, Ensuring safety and health at work in a changing climate, 2024

That’s why we are developing Tempesta, the first active thermal regulation system based on space and nuclear technologies, designed to be integrated directly into your work clothes to guarantee resistance to extreme temperatures while maintaining performance.
