It started with a question in a sauna.

At 21, I was studying abroad when a fluke accident changed everything. I hit my head on the bottom of a shallow pool and fractured a small bone in my neck. What followed was inflammation, pain, and a year and a half of brain fog, chronic fatigue, and low energy that I blamed entirely on the injury.

When conventional answers ran out, I worked with a functional medicine practitioner and got full blood work. The inflammation was expected. What wasn't: at 23, my testosterone was far below where it should have been for my age.

It didn't add up. I trained hard, ate clean, lived in the South Florida sun, and loved what I was doing. So I started digging into everything around me, and that's when I learned about chemicals linked to endocrine disruption, and how many everyday products carry them. One by one, I swapped out my deodorant, my soap, my household products.

Then, about 18 months ago, I was sitting in a 200-degree sauna, sweating heavily, wearing nothing but compression shorts. And I looked down and thought: what are these actually made of? This fabric sits on the most sensitive part of my body every day, and right now it's soaked in heat and sweat.

I checked the tag. 100% polyester.

A quick search told me what I should have known: polyester is plastic, a fabric made from petrochemicals. I'd cleaned up nearly everything else in my life and missed the thing I wear longest.

The switch flipped. I went looking for underwear built without plastic where it matters, that could still handle real training. I figured a brand would find me within days. Two weeks later, I still hadn't found what I was looking for.

So we built it.

NADS is made from GOTS-certified organic cotton, grown without synthetic pesticides and verified by an independent textile standard, with OEKO-TEX-tested dyes and no plastic at ball contact. It's the upgrade I wanted for myself, and it turns out I wasn't the only one looking.

You upgraded everything else. Your base layer is next.
