We sweat in them. We stretch in them. We live in them. But almost no one is asking the most important question: What’s actually in the fabric touching your skin? PFAS, also known as “forever chemicals,” are commonly used in activewear for sweat resistance, stain resistance, odor control, and durability. But here’s the problem: leggings are worn tight against your skin. Add heat, friction, sweat, and increased blood flow, and absorption risk goes way up. PFAS have been linked to hormonal disruption, thyroid dysfunction, fertility challenges, immune suppression, and increased cancer risk. Yet there is no requirement for most clothing brands to test their finished garments for PFAS, heavy metals, BPA, phthalates, or microplastics. So instead of trusting marketing claims, Dr. Christian Gonzalez reached out to 76 activewear brands with one simple question: Do you test your finished garments for PFAS, and can you provide a third-party Certificate of Analysis (CoA) to prove it? The results were shocking. In this episode, Dr. G breaks down: • Why performance fabrics often rely on chemical finishes • How PFAS exposure increases with tight, sweat-heavy clothing • Why raw fabric certifications don’t equal clean finished products • The difference between supplier testing and third-party finished garment testing • Which major brands failed to respond at all• The only brand (out of 76!) that provided full third-party lab testing This isn’t about attacking brands. It’s about transparency. If you wear leggings, sports bras, or athleisure wear, this is a conversation you need to hear before your next purchase.

0:00.0	Nike, Lulu Lemon, Viori, Alo, Jim Shark, I reached out to 76 activewear brands and asked them one question, do you test for PIFAs?
0:09.9	Pfeas or Forever Chemicals are added to leggings for sweat resistance, stain resistance, and odor control.
0:15.6	But here's the problem. You wear leggings tight to your skin. You sweat, blood flow increases, and those chemicals can absorb right into your body.
0:23.6	Why is that a problem? PIFAs have been linked to hormonal disruption, fertility issues, immune suppression, and increased cancer risk.
0:30.6	So out of 76 brands, only one brand fully passed my testing standards.
0:35.6	If you wear athletic leggings, at leisure, watch this before you buy your next pair. So you see the brands everywhere.
0:41.8	Nike, Lulu Lemon, Viori, Allo, Jim Shark, Patagonia, whatever it is. They're in your gym,
0:46.5	your Instagram feed. They all sell the same story. Performance, sustainability, clean materials,
0:53.5	quote unquote. But here's a question that almost no one
0:56.0	really asks, what is actually in the fabric that is touching your skin? You see, the problem with
1:01.5	active wear, it's not like jackets or jeans. Leggings and sports bras are worn tight. And what are
1:07.9	you doing them? You sweat. There's heat friction, there's increased blood flow.
1:12.2	That matters. Because this category quietly relies on chemical treatments, and those chemical
1:18.3	treatments make these fabrics do what they do. The sweat resistance, the stain resistance,
1:24.0	the odor control, the quick drying, and the most common chemical that is used for this
1:28.7	process are PIFAs. Their per and polyfluoral alcohol substances, these are the forever chemicals,
1:35.7	one of the nastiest chemicals in existence. And they do not break down in the environment. And just
1:41.3	like the environment, they don't break down in your body. And the problem is,
1:44.5	most of these atleisure brands never test their finished garments for them. So instead of trusting
1:50.7	the marketing, I decided, let me run an investigation. I reached out to 76 activewear brands,
1:57.2	the biggest brands, the smallest brands, the ones that claim sustainability,
2:04.5	women-owned brands, it didn't matter. I asked for one thing.
