Overview

Jordan Harbinger interviews Chris Colby, a 30-year apparel industry veteran and founder of Hypernatural Clothing, about the hidden health risks in synthetic performance fabrics. They explore how polyester, nylon, and spandex dominate modern wardrobes despite being coated with potentially harmful chemicals including PFAS, phthalates, and toxic dyes. The conversation covers how heat, sweat, and friction activate these chemicals to leach into skin, the marketing myths around 'performance' fabrics, and practical steps consumers can take to make safer clothing choices without completely overhauling their closets. Colby introduces bio-based alternatives using natural materials like chitin from shellfish and jade stone that provide genuine performance benefits without chemical treatments.

The Hidden Chemical Crisis in Your Closet

Most people don't realize that polyester, nylon, and spandex are actually plastic coated with industrial chemicals to achieve performance characteristics like moisture-wicking and wrinkle-resistance. When asked if they wear plastic on their bodies, people are shocked to learn that their workout clothes contain chemicals that leach into skin, especially when activated by heat, sweat, and friction. The fashion industry has successfully marketed synthetic fabrics as essential for performance, but consumers remain largely unaware that these materials can have adverse health effects when worn during exercise.

  • Polyester, nylon, and spandex are forms of plastic requiring chemicals like phthalates (hormone disruptors) to make them soft and pliable
  • Most people know plastic is bad for the environment but don't realize it's bad for their bodies
  • Chemicals are both inherent in plastic fibers and applied topically for performance features like quick-dry and water resistance
  • The industry solved for performance but created a worse health problem than wearing cotton to the gym
" When you ask people, do you realize polyester is plastic, and plastic is coated in chemicals to give it certain performance characteristics, the overwhelming population does not know, is not aware. "
" The industry's kind of solved for performance, but then created a much worse problem than, oh my gosh, I have a cotton shirt on at the gym. "
