MOISTURE-WICKING ISN'T A FEATURE. IT'S A FOREVER CHEMICAL.

And it soaks into the most absorbent skin you have, all day. It's linked to lower testosterone and reduced fertility in men. NADS leaves it out.

FIRST, WHAT IS PFAS?

You've heard "forever chemicals" in the news. Here's the plain version:

PFAS is a class of chemicals built to repel water, oil, and stains.

Here's why they're a problem...

This isn't a vague "chemicals are bad" worry. PFAS exposure is linked to:

  • Lower testosterone

  • Reduced fertility

  • Hormones knocked off balance

The systems you train and eat clean to protect.

In plain English, that's the stuff you care about most:

Your drive and your energy

  • Your recovery after you train

  • Your shot at starting a family when you're ready

You audit every input for these. This is the one nobody told you to check.

And this one you don't just live near. You wear it:

Against the most absorbent skin on your body

  • 16 to 18 hours a day

  • Warm, damp, and under constant pressure

Heat and sweat open the door. Your skin pulls it in like a sponge, all day, every day.

The bottom line...

Wear PFAS-treated fabric, and you accept a forever chemical, linked to lower testosterone and reduced fertility, soaking into the most sensitive skin you have. Every day.

NADS went the other way:

  • No performance finishes to add

  • GOTS-certified organic cotton, farm to garment

  • OEKO-TEX tested, screens for harmful substances including PFAS

  • No plastic at ball contact

The one PFAS source you can actually take off. Done in one purchase.
