Fabric Safety
A Higher Performance Standard
Performance fabric you can trust against your skin.
Every article independently tested free from BPA, PFAS, and 50+ harmful chemicals.
What We Believe
The clothes you stretch in, sweat in, recover in — should be the cleanest things you own.
What We Verify
Every product, tested clean.
Common in recycled polyester. An endocrine disruptor linked to hormonal imbalance.
“Forever chemicals” that accumulate in the body and don’t break down. We never apply any PFAS treatments (e.g., quick dry).
Plasticizers used to soften fabric. Known endocrine disruptors. You’ll find none in our gear.
Can appear in dyes and pigments. A potent neurotoxin with no safe level. Our dyes are bluesign approved.
Sometimes used for wrinkle resistance. A known carcinogen. We don’t use it, and we prove it with every test.
Cadmium, chromium, antimony, and others found in dyes and coatings. Just not ours.
Sustainable Synthetics
Not all synthetics are created equal.
The case
Synthetic fabrics offer the best performance available — stretch, moisture management, durability.
The problem
Traditional synthetics are often treated with chemicals like PFAS and BPA and shed microplastics that last for centuries.
Our answer
Our performance fabrics are infused with CiCLO® — an OEKO-TEX® certified fiber technology designed to accelerate biodegradability.
“I’ve tried every sustainable brand and these are the best by a wide margin!”— Jenny C, verified buyer
Synthetics that biodegrade.
Our fabrics use CiCLO® technology — natural compounds embedded throughout the fiber that attract microbes when discarded.
Same stretch. Same durability. Built-in exit strategy.
Common Questions
Are synthetic fabrics safe?
Synthetics like polyester and nylon aren’t inherently harmful — it’s what they’re treated with that matters. Chemical finishes are often applied to enhance performance.
Do natural fabrics have the same chemical concerns?
Natural doesn’t mean untreated. Cotton, wool, and other natural fabrics are routinely treated with PFAS, formaldehyde, and other harsh chemicals.
What does “non-detect” mean in your lab reports?
Non-detect means the lab found nothing above its instrument’s lowest measurable threshold. It’s the strictest possible result.
What makes your testing standard different?
We test to non-detect, which means if the lab can find it, we don’t use it. Many certifications allow “acceptable limits” of harmful chemicals.
What is CiCLO® and how does it work?
CiCLO works by embedding natural compounds throughout the synthetic fiber. When discarded fabrics reach landfill or ocean environments, microbes are attracted to these compounds.
Why is BPA a concern in activewear specifically?
During exercise, your pores are open, body temperature is elevated, and sweat creates a pathway for chemical absorption.
Do you have a Code of Conduct for your suppliers?
Yes. All of our suppliers meet our Supplier Code of Conduct. Our Founder has also personally visited each factory.
