Synthetic Toxins and Endocrine Safety: Why Non-Toxic Gear Matters

Most people don’t realize how much contact their activewear has with their body — or how much that contact can actually matter. Your skin is your largest organ, and it absorbs far more than you might think, especially during intense workouts. That’s why non-toxic activewear isn’t just a feature of the EveryRep brand — it’s a foundation. It’s essential to your health.

When you’re moving, stretching, and sweating, your pores open up. That’s when synthetic fabrics like polyester and nylon — often treated with toxic chemicals — can start to leach harmful substances into your skin. The activewear industry is saturated with petroleum-based materials that contain BPA, PFAS, phthalates, and other endocrine-disrupting additives. These aren’t just bad for the environment — they’re dangerous to your body.

For women, that danger is especially serious when it comes to reproductive health, hormonal balance, and long-term fertility. These chemicals are known to interfere with estrogen levels and have been linked to increased skin irritation, inflammation, and systemic hormone disruption.

And for men, it’s no different. Prolonged exposure to endocrine disruptors — particularly in high-heat, high-friction zones like compression shorts and underwear — can impact testosterone levels, sperm quality, and overall hormonal function. The risks are real, and they’re closer than you think — right next to your skin.

At EveryRep, we design performance wear that puts your body first. We use natural, plant-based fabrics like TENCEL™ Modal, known for their ultra-soft feel and breathable, moisture-wicking performance. Our materials are free from BPA, PFAS, and other toxic treatments, because we believe performance shouldn’t come at the cost of your health.

It’s the difference between wrapping yourself in plastic… or wrapping yourself in nature.

Once you feel it, you’ll never go back.
