What is PFAS and Why Your Activewear Should Be PFAS-Free

If you've been paying attention to sustainable fashion news lately, you've probably heard the term "PFAS" or "forever chemicals" mentioned alongside activewear and outdoor clothing. But what exactly are PFAS, why are they used in gym clothes, and should you be concerned?

The short answer: Yes, you should care about PFAS in your activewear. Here's everything you need to know about these harmful chemicals and how to choose safer, PFAS-free alternatives.

What Are PFAS?

PFAS stands for per- and polyfluoroalkyl substances—a group of over 9,000 synthetic chemicals that have been used in consumer products since the 1940s. They're often called "forever chemicals" because they don't break down in the environment or in our bodies.

You might recognise PFAS from:

  • Non-stick cookware (Teflon)
  • Stain-resistant carpets and furniture
  • Water-resistant outdoor gear
  • Food packaging
  • Performance activewear and sportswear

Why Are PFAS Used in Activewear?

PFAS are added to activewear fabrics to create:

  • Water resistance: Repels sweat and moisture
  • Stain resistance: Prevents marks and discolouration
  • Durability: Helps fabrics last longer

Sounds great for performance, right? Unfortunately, the health and environmental costs far outweigh these benefits.

The Problem with PFAS: Health and Environmental Concerns

Health Risks:

Research has linked PFAS exposure to:

  • Hormone disruption
  • Immune system suppression
  • Increased cholesterol levels
  • Thyroid disease
  • Certain cancers
  • Developmental issues in children
  • Reduced vaccine effectiveness

Because PFAS don't break down, they accumulate in your body over time. When you wear PFAS-treated activewear, these chemicals can be absorbed through your skin—especially during sweaty workouts when your pores are open.

Environmental Impact:

  • PFAS contaminate water supplies, soil, and wildlife
  • They persist in the environment for thousands of years
  • Washing PFAS-treated clothing releases microplastics and chemicals into waterways
  • Manufacturing PFAS pollutes communities near production facilities

How to Identify PFAS in Activewear

Unfortunately, brands aren't required to disclose PFAS on labels. Look out for these marketing terms that often indicate PFAS treatment:

  • "Water-resistant" or "water-repellent"
  • "Stain-resistant"
  • "DWR" (Durable Water Repellent)
  • "Moisture-wicking" (though not all moisture-wicking fabrics contain PFAS)

The Good News: PFAS-Free Alternatives Exist

Modern textile technology has developed PFAS-free alternatives that deliver excellent performance without the health risks:

1. Mechanical Moisture-Wicking
Fabrics engineered with special weaves and fibre structures that naturally pull moisture away from skin without chemical treatments.

2. Plant-Based Water Repellents
Wax-based or bio-based coatings derived from natural sources.

3. Advanced Synthetic Fibres
Recycled nylon and polyester designed for quick-dry performance without PFAS additives.

Choosing PFAS-Free Activewear: What to Look For

Certifications:

  • OEKO-TEX Standard 100: Tests for harmful substances including PFAS
  • bluesign® approved: Ensures chemical safety in textile production
  • GOTS (Global Organic Textile Standard): For organic cotton products

Transparent Brands:

Look for companies that:

  • Explicitly state "PFAS-free" on product pages
  • Share third-party test results
  • Disclose their chemical management policies
  • Prioritize sustainability and health

Making the Switch: Your Action Plan

  1. Check your current activewear: Research brands to see if they use PFAS
  2. Replace gradually: Start with pieces you wear most often
  3. Look for certifications: OEKO-TEX and bluesign® are your friends
  4. Ask brands directly: If information isn't available, email and ask about PFAS
  5. Spread the word: Share this information with your fitness community

The Bottom Line

PFAS in activewear is an unnecessary risk to your health and the environment. With PFAS-free alternatives readily available that perform just as well (if not better), there's no reason to expose yourself to forever chemicals during your workouts.

Your activewear should support your health goals, not undermine them. Choose PFAS-free, and feel good about what you're wearing—inside and out.
