About Definite Articles

The clothes you sweat in, stretch in, heal in — should be the cleanest things you own. We built Definite Articles to make sure they are. We independently test every finished product for BPA, PFAS, phthalates, lead, formaldehyde, and dozens of other harmful substances. Our standard is non-detect: if the lab's instruments can find it, we don't use it. Environmental responsibility is the second half of the equation. We infuse our performance fabrics with CiCLO® technology, allowing durable synthetics to biodegrade once discarded instead of persisting for centuries. The result is significantly reduced long-term microplastic pollution — without sacrificing stretch, durability, or comfort. The outcome is premium activewear — leggings, sports bras, joggers, hoodies, and socks — built for real training: squat-proof, supportive, buttery soft, and designed for daily wear. Certified B Corp.
