Why I Had to Build a Shirt That Would Outlive You

By Chuckie, Founder of Undrdog

The Day Every Shirt Let Me Down

I've been hustling since I was a kid. Built brands. Helped millions. But shirts? That's where my obsession kicked in.

Every shirt I loved betrayed me.

They lost shape
They stunk
They shrunk
They tore
They faded

And a few months later, I'd be back ordering more. It pissed me off.

It felt like the whole industry was built for someone else, not for guys like me.

At first, I just wanted a shirt that didn’t fall apart.

But that frustration opened my eyes to something much bigger.

The Wake-Up Call

That's when life hit me harder than any workout.

After four years of trying to have a baby with my wife, I began to investigate why things weren't working.

What I discovered shocked me.

Polyester.

Specifically, the PFAS chemicals are hidden inside it.

The same toxins are linked to cancer, hormone disruption, infertility, and even birth defects.

Research shows that polyester leaches microplastics directly into our bloodstream. Through our skin.

And here I was, sweating in it every day.

That felt like someone ripped my heart out.

And here we all were, wearing it every day, completely unaware of its significance.

The Decision

When I realized how toxic it was, I knew the industry wouldn’t change.

I had a choice. Watch the world continue to wear poison or build
something better.

No brand was even asking the right question. So I asked myself:

The Decision

How do I make a shirt that's strong, breathable, and comfortable without poisoning people?

That question changed everything.

Making the World's Strongest Shirt

I had one goal: create the world's strongest shirt with a lifetime warranty.

Making the World's Strongest Shirt

One shirt I could live in, train in, and trust forever.

And, yeah, I wanted it to fit my biceps and conceal my gut.

Hemp seemed like the answer. Earth's toughest fabric.

No toxins.
No coatings.
No synthetic shortcuts.

If polyester were poisoning people, I wanted to prove that nature could outperform it.

Hemp seemed like the answer. Earth’s toughest fabric.

But there was a problem.

100% hemp shirts were stiff. Cardboard.

Not breathable. Not practical for real life.

So I kept searching.

The Breakthrough

I knew hemp was the toughest natural fiber on the planet. Sails. Ropes. Even military uniforms. It doesn't quit.

Where the industry saw problems, I saw potential.

But on its own, it was too stiff. Too heavy. So I asked myself:

"What if I could combine hemp's strength with something softer, lighter, and more breathable?"

That's when I turned to bamboo.

Bamboo is naturally breathable. It's softer than cotton. It wicks moisture without needing toxic coatings.

The problem? Nobody had ever successfully blended hemp and bamboo into a fabric that could last.

If no one else would, I’d do it myself.

So I created the technology to do it.

Almost a Year of Trial and Error

It wasn't easy.

For nearly a year, I tested and failed.

The blends were too weak. Too rough. Too inconsistent.

But I refused to give up.

Because I wasn't just chasing comfort. I was chasing forever.

Finally, after dozens of failed prototypes, I cracked it.

And when I wore it, I knew instantly this was different.

The Forever Tee Was Born

From that moment, I stopped thinking about "just another shirt."

I wanted to end disposable fashion.

Polyester may look "performance-ready" on day one. But after a few weeks, it's sagging, stinking, and poisoning your skin.

The Forever Tee?
