Materials

73% Ciclo Nylon, 27% Spandex

Tested, Tried & True: Independently lab-tested free from BPA and PFAS. Most brands won’t claim this — because they can’t.

Premium Performance Yarns: Our high-quality, fully traceable yarns are sourced through sustainable partners, including a family-owned mill in the U.S. These materials meet rigorous chemical safety standards and are independently verified for harmful substances through certifications such as STANDARD 100 and ECO PASSPORT by OEKO-TEX®.

Biodegradable Innovation: We use CiCLO®-enabled yarns—certified by ECO PASSPORT by OEKO-TEX®—that allow yarns like nylon and polyester to biodegrade in the environment more like natural fibers. Instead of persisting for centuries, these yarns break down in a matter of years when exposed to landfill or ocean conditions.

Recycled materials, minimal waste: Our commitment to protecting the planet starts with sustainable fibers and yarns. We use synthetic yarns made from recycled plastic bottles which helps remove ocean plastic and repurpose unused short fiber from the yarn spinning process. Our sports bras are designed to minimize waste and environmental impact—without compromising on performance or comfort.

Premium Performance Apparel

The clothes you sweat, stretch, and recover in should be the cleanest ones you own. That’s the standard. We just make it possible.

Definite Articles was built on a simple belief: performance apparel should meet a higher material standard. You shouldn’t have to choose between gear that performs and products you can trust. From day one, we’ve taken a different approach. Every finished garment is independently tested by third-party labs to verify it’s free from substances like PFAS, BPA and 50+ harmful chemicals. Because what matters isn’t just the starting yarn, it’s the final product against your skin.

Our products are designed for real training, delivering the durability, support, and feel expected from premium activewear. As more people start asking what’s actually in their clothing, we’ve focused on providing clear answers through verified testing, considered materials, and full transparency.

Raising the material standard in activewear

Definite Articles started with a gap that became hard to ignore. Performance was being solved, but material clarity wasn’t.

Most brands speak to inputs. We focus on outcomes.

That means testing the finished garment, where chemical exposure can actually occur, and building products that maintain high performance without compromising on material integrity.

Better performance. Verified safety. Transparency that holds up under scrutiny.
