Is There PFAS in Your Workout Clothes in 2026? What the Lululemon Investigation Means for You

If you live in leggings and moisture-wicking tops, a new investigation out of Texas may have caught your attention. The Texas attorney general's office is examining whether Lululemon's clothing contains PFAS, the class of synthetic "forever chemicals" linked to a range of health concerns, according to Health.com. Here's what's actually known so far, why activewear is even part of this conversation, and what you can do while the investigation plays out.

What Happened With the Lululemon PFAS Investigation?

According to Health.com, the Texas attorney general's office has opened an inquiry into whether Lululemon products contain PFAS chemicals, despite the brand's public messaging around performance and quality. The investigation is examining the company's testing, disclosures, and marketing claims related to these chemicals. As of this reporting, the probe is ongoing, and no findings, fines, or product recalls have been announced. Lululemon has not been shown to have violated any law; an investigation means regulators are asking questions, not that wrongdoing has been proven.

What Are PFAS, and Why Would They Be in Clothing?

PFAS (per- and polyfluoroalkyl substances) are a family of thousands of manufactured chemicals prized for their ability to repel water, oil, and stains. That's exactly why they've historically been used in items like nonstick cookware, waterproof jackets, carpeting, food packaging, and yes, some performance and athletic apparel, according to the U.S. Environmental Protection Agency (EPA).

In activewear specifically, PFAS-based treatments have sometimes been applied to help fabric resist sweat stains, water, and odor, or to make certain moisture-wicking finishes more durable. Because PFAS chemicals contain extremely strong carbon-fluorine bonds, they don't break down easily in the environment or the body, which is where the "forever chemicals" nickname comes from.

Who and What Is Affected?

Right now, the investigation centers on Lululemon and its supply chain and testing practices, but the broader question, whether PFAS are present in athletic and everyday clothing, extends well beyond one brand. Many apparel companies have used PFAS-based durable water repellent (DWR) finishes in the past, and regulators and researchers across the industry have been scrutinizing textile treatments more closely in recent years.

Consumers who regularly wear moisture-wicking, "sweat-resistant," or water-repellent activewear are the group most directly relevant to this story, simply because those finishes are where PFAS use has historically been concentrated, per industry and regulatory reporting.

Why Does This Matter for Your Health?

Health agencies, including the EPA and the Agency for Toxic Substances and Disease Registry (ATSDR), have noted that some PFAS chemicals are associated with a range of health effects in scientific studies, including impacts on cholesterol levels, liver function, immune response, thyroid function, and certain cancers. It's important to be precise here: these are associations found in population-level research, not proof that any single product or exposure causes a specific health outcome in an individual.

Clothing is also just one potential PFAS exposure source among many, alongside drinking water, food packaging, household dust, and certain personal care products. Skin contact with treated fabric is generally considered a smaller exposure pathway compared to ingestion or inhalation, according to environmental health researchers, though scientists continue to study how much clothing contributes to overall PFAS body burden.

What Should You Do Right Now?

You don't need to panic-purge your closet, but a few practical steps can help you feel more in control:

• Check brand disclosures. Some apparel companies now publish PFAS-free commitments or third-party testing results for specific product lines. Look for explicit statements rather than vague "eco-friendly" marketing.
• Be skeptical of vague water-repellent claims. Terms like "stain-resistant" or "water-wicking" don't automatically mean PFAS are present, but they're worth asking about if a brand doesn't specify its finishing chemicals.
• Wash new performance gear before wearing it, which may help reduce surface residues, though it won't eliminate PFAS embedded in a fabric's finish.
• Diversify your exposure sources. Since clothing is just one potential contributor, also consider PFAS in your drinking water and food packaging, where exposure may be more significant.
• Use a trusted resource to compare products. Our PFAS product finder can help you look up specific brands and categories, and our methodology page explains how we evaluate and rate PFAS-related claims.

Bottom Line

The Texas attorney general's investigation into Lululemon is a fact-finding inquiry, not a confirmed finding of PFAS contamination or wrongdoing. Still, it's a useful reminder that PFAS chemicals have a documented history in some textile treatments, and that "performance" marketing doesn't always disclose the specific chemicals used to achieve it. Until more is known, activewear treated for water or stain resistance falls into a lower concern but not zero concern category, worth watching as the investigation unfolds, and worth asking brands direct questions about.

Frequently Asked Questions

Has Lululemon been confirmed to use PFAS in its clothing?

No. As of this reporting, the Texas attorney general's office is investigating whether PFAS are present in Lululemon products, according to Health.com. No official findings have been announced, and Lululemon has not been shown to have violated any law.

Can PFAS in clothing be absorbed through the skin?

Researchers generally consider skin contact a smaller PFAS exposure pathway compared with ingestion or inhalation, though scientists are still studying how much clothing may contribute to overall PFAS exposure, according to environmental health experts.

How can I find out if my clothes contain PFAS?

Look for explicit PFAS-free claims or third-party testing disclosures from brands, since vague marketing terms like "water-resistant" don't confirm or rule out PFAS use. You can also use tools like our product finder to research specific items.
