The clothes you sweat, stretch, and recover in should be the cleanest ones you own.
That's why we built Definite Articles from the ground up around one standard: nothing that performs well should also harm you. Every article is independently tested for BPA, PFAS, and 50+ chemicals — and made with one of the lightest environmental footprints in activewear.
Sustainable Synthetics
Not all performance fabric is created equal.
The trade-off
For decades, performance and safety have been treated as a trade-off. Better stretch, moisture management, durability — but at what cost to your body and the environment?
The problem
Traditional synthetics are often treated with chemicals like PFAS and BPA and shed microplastics that last for centuries. These toxic microplastics enter waterways, accumulate in ecosystems, and make their way into our food chain.
Our answer
Our fabrics are made to break down — not accumulate. CiCLO® fiber technology significantly accelerates biodegradability without compromising stretch, moisture management, or durability. Every finished garment is independently tested to verify it's free of BPA, PFAS, and 50+ other harmful substances.
We're not claiming perfection. We're claiming the highest standard available.
As seen in
Articles made to last, just not forever.
Thanks to CiCLO® technology, our performance fabric will biodegrade when discarded like wool or cotton - dramatically reducing long-term microplastic pollution. This is done without any impact to fabric performance.
