This post is inspired by the article “Leaving a Trace” by Sam Pyrah, published in BBC Countryfile Magazine (September 2025). We’re highlighting the key takeaways for ecoKallos readers who care about sustainable living and conscious choices in their outdoor gear.
When we head into the countryside, we’re reminded to “leave no trace.” Yet many of the clothes and equipment we rely on for our adventures leave an invisible trace — PFAS, the so-called “forever chemicals.”
These chemicals make our jackets waterproof, our boots resistant to mud, and our tents sturdy against the rain. But their long-lasting performance comes with a hidden cost to our health and the environment.
What Are PFAS?
PFAS (per- and polyfluoroalkyl substances) were first developed in the 1930s — Teflon being one of the earliest examples. Because they repel water, oil, dirt, and heat, PFAS are used in:
- Waterproof jackets, hiking boots, and tents
- Sleeping bags and rucksacks
- Sunscreens, cosmetics, and even food packaging
It’s this incredible durability that made them so popular — and so persistent.
Why They’re a Problem
Unlike natural materials, PFAS don’t break down. Instead, they accumulate in:
- Soil, water, and air
- Wildlife, from fish to birds
- Human bodies — detected in 97% of Americans and even in newborn babies
Health research has linked PFAS to:
- Cancers
- Fertility and pregnancy complications
- Low birth weight
- Hormone disruption
- Weakened immune systems
From the top of Everest to the bottom of the ocean, PFAS are everywhere — leaving a trace we can’t ignore.
How They Get Into the Environment
It’s not just wearing a waterproof jacket that releases PFAS. The bigger issue is manufacturing and disposal.
PFAS are used in two main ways:
- Durable Water Repellent (DWR) coatings that make water bead off fabric.
- Microporous membranes (like Gore-Tex) that keep gear breathable yet waterproof.
They also sneak into zips, laces, and other components that don’t even need waterproofing.
Brands Leading the Way
Thankfully, some outdoor brands have stepped up to eliminate PFAS:
- Páramo (UK) – always PFAS-free, using “directionality” technology instead of chemicals.
- Keen (US) – PFAS-free footwear since 2018.
- Patagonia (US) – entire range now PFAS-free.
- Alpkit (UK) – switched to PFAS-free clothing and tents.
- Finisterre (UK) – offering PFAS-free garments.
- Fjällräven (Sweden) – fully PFAS-free.
- Vaude (Germany) – fully PFAS-free.
These pioneers show it’s possible to protect both adventurers and the planet.
Legislation and Regulation
Governments are beginning to act:
- New York & California – bans on PFAS in textiles started January 2025.
- France & Denmark – phasing out PFAS in clothing and gear between 2026–2030.
- EU – moving toward a universal ban on all non-essential PFAS.
- UK – still behind, with campaigners urging stronger action.
What You Can Do as a Consumer
- Choose PFAS-Free Brands – support companies investing in safer alternatives.
- Care for Your Gear – PFAS-free fabrics may need more frequent washing and re-proofing.
- Keep What You Already Own – the most sustainable jacket is the one you don’t replace.
- Stay Informed – check resources like Ethical Consumer’s 2024 report for updates.
Final Thoughts
Outdoor gear should protect us from the elements — not pollute the very landscapes we love. The rise of PFAS-free innovation shows that a safer future is possible, but it depends on consumer demand, brand responsibility, and strong legislation.
✨ Next time you gear up for an adventure, remember: leaving no trace starts with what you choose to wear and carry.
