PFAS‑Free.
No compromise.
Forever chemicals have no place in performance wear. We made that decision on day one — and we have never looked back.
What are PFAS?
Per and polyfluoroalkyl substances are a family of synthetic chemicals used in thousands of products — including most performance athletic wear. They are called forever chemicals because they do not 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. But at what cost?
- 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
- 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
Zero compromise.
From day one.
At Seissense, we made a decision from day one. No PFAS. Ever. We believe performance should not come at the cost of your health or our planet. Every single piece is engineered completely free of PFAS and all related synthetic fluoro-chemicals.
- Zero added PFAS in any fabric, treatment, or finishing process
- Rigorous third-party testing of every material we source
- Complete supply chain transparency from fibre to finished garment

More than a feature.
It is a philosophy.
Being PFAS-free shapes every decision we make — from the materials we source to the standards we set for the industry.
