natural fiber activewear

Most activewear is polyester or nylon with elastane, and performance finishes on leggings and tops can include PFAS, the 'forever chemicals' used to repel water and odor. Worn tight against sweating skin, that combination is a real exposure. Toxome scores each piece by fiber so you can choose natural-fiber options.

PFAS often show up in the water-repellent and sweat-wicking finishes on performance gear. Not every piece carries them, but they are common in conventional activewear. Choosing activewear built on natural fibers, without the performance finishes, is the simplest way to avoid them.

Fiber content is what touches the skin. Toxome reads each garment's composition and rates it, so the score reflects what the clothing is made of, not a brand's marketing.
