Why We Say No to PFAS and Harmful Chemicals 

PFAS (short for per- and polyfluoroalkyl substances) are a group of “forever chemicals” often added to clothing for water resistance, stain repellency and durability. The problem? They don’t break down naturally. Once released, they persist in waterways, soil, wildlife and even our bodies. 

Studies have linked PFAS exposure to serious health concerns, including hormone disruption, immune system impacts and increased cancer risk. And because these chemicals travel far beyond factories, they affect entire ecosystems — not just the people making or wearing the products. 

That growing awareness is driving change. Recent legislation in California now bans PFAS in many consumer textiles, and France has passed similar regulations targeting these harmful chemicals in apparel. Momentum is building globally — and we’re proud to already be aligned with that future. 

We design Tellus products with people and planet in mind from the very beginning. That means avoiding intentionally added PFAS and other harmful finishes whenever possible, choosing certified materials, and working with partners who share our commitment to safer chemistry. 

Instead of relying on toxic coatings, we prioritize: 

• Thoughtfully sourced recycled fabrics 
• Responsible manufacturing standards 
• Durable designs that reduce the need for constant replacement 

Because sustainability isn’t just about recycled fibers — it’s about the full lifecycle of a garment, from raw materials to the rivers it touches. 

We believe outdoor clothing should support adventure and environmental health. You shouldn’t have to compromise one for the other. 

And as always, 100% of Tellus net profits go directly to environmental conservation and restoration — so every purchase helps protect the wild places we all love. 

What does PFAS-free mean at Tellus? It means we avoid intentionally adding PFAS treatments to our fabrics and seek safer alternatives. 

Why are harmful chemicals still used in clothing? They’re often cheap, effective and deeply embedded in traditional supply chains. Changing that requires innovation — and commitment. 

Does PFAS-free mean less performance? Not necessarily. Modern material science offers durable, weather-ready options without relying on forever chemicals. 

How does this help the environment? Reducing toxic inputs protects waterways, wildlife and communities — especially those closest to manufacturing hubs. 

What can customers do to help? Support brands that prioritize clean materials, buy fewer but better products and care for your gear to extend its life.
