PFAS-Free by Design
No forever chemicals. No hidden risks. Every Seissense piece is built with no added PFAS, designed to protect you and the planet.
What Are PFAS?
Understanding "forever chemicals"
PFAS: polyfluoroalkyl substances: are a family of synthetic chemicals used in thousands of products, including most performance athletic wear.
They're called "forever chemicals" because they don't break down in the environment or in your body.
For decades, activewear brands have relied on PFAS to achieve water resistance, stain protection, and moisture-wicking performance.
But at what cost?
The Impact on Your Health
What PFAS can do
- Accumulate in blood and organs over time
- Disrupt hormone function and thyroid health
- Weaken immune system response
- Linked to increased cholesterol levels
- Associated with certain cancers
- Affect reproductive health and development
The Impact on Our Planet
What PFAS do to the environment:
- Persist in soil and water indefinitely
- Contaminate drinking water supplies
- Accumulate in wildlife and food chains
- Cannot be filtered by conventional treatment
- Spread globally through air and ocean currents
- Found in remote Arctic regions and deep oceans
