Hey, I’m Chuckie!
Founder of UndrDog Hemp.
Making the World's Strongest Shirt
I had one goal - to create the World’s Strongest Shirt with a Lifetime Guarantee.
Also, fit to grip my biceps and hide the gut.
Hemp was the answer, right? Earth’s toughest fabric.
But 100% hemp shirts were like wearing cardboard. Not comfortable, breathable, or practical for real life.
The Search for Perfection
I needed something durable, breathable and comfortable.
First attempt… I blended hemp with polyester.
BOOM—created the world’s strongest shirt with a lifetime guarantee.
It wasn’t super breathable, but UndrDog Hemp took off. Success!
But then, everything changed…
The Wake-Up Call
After four years of trying to have a baby with my wife, I researched why things weren’t working.
I came across something linked to infertility that I didn’t expect to see: Polyester.
Specifically, the PFAS chemicals it contains. Along with links to cancer, birth defects, and a host of other health problems.
Research says wearing polyester leeches toxic microplastics straight into our bloodstream.
Felt like someone ripped my heart out!
I kept digging, and here’s the cold, hard truth about the health risks caused by PFAS and microplastics:
Cancer:
Increased risk for liver, kidney, and testicular cancer.
Shrinkage:
Yeah, shrinkage in all the wrong places–your taint, balls, and penis.
Infertility:
Links to reproductive issues and infertility.
Hormone Disruption:
It lowers testosterone, sex drive, and muscle growth.
Brain Degeneration:
Linked to memory loss, cognitive decline, and Alzheimer's.
Birth Defects:
Linked to preterm birth, low birth weight, and developmental delays.
The Pivot
I had a choice: keep selling toxic shirts like everyone else, or fix it.
I chose to do better.
I went back to the drawing board with one question…
How to make a strong, breathable and comfy shirt with a lifetime guarantee WITHOUT toxic chemicals.
Goodbye Polyester, hello Bamboo!
It breathed like a dream, airflow-heaven, soft and comfy, but it was weak.
So I thought,
“Why not combine Hemp’s strength and Bamboo’s breathability?”
No method existed to blend these two magic fibers successfully. So, we created the technology.
After almost a year of trial and error, we created something that had never been done before.
Enter: DuraFlow™ – our innovative, patented fabric technology blending hemp, bamboo, and organic cotton.
The most satisfying midweight shirt - Durable, breathable, and comfortable—Like a man-hug without feeling weird.

Hides Gut & Man Boobs
“UndrDog shirts high-five every muscle; even your shadow will flex and turn people on”
Hemp’s firm resilience clings to your body in all the right places.
Unbeatable Breathability
“UndrDog Shirts don't just breathe; they give air permission to pass through.”
Stay cool with Bamboo's natural breathability airflow.
4x Stronger Than Cotton
“When your UndrDog shirt enters the wardrobe, cotton shirts unravel themselves in fear.”
High-tensile hemp makes this shirt almost indestructible.
300% More Sweat Resistant than Ordinary Cotton Tees
“UndrDog shirts don’t just resist sweat; they make it evaporate in awe.”
Hemp creates a natural barrier that is moisture-wicking (keeping you dry and smelling better than you should)
“IT’S A F’KN WEIRD PLANT!”
Trailblazing platforms like Joe Rogan and TEDx are tearing down the veil, exposing the truth of hemp’s unmatched superiority!
Did you know?
Before it got banned in the 1930s, hemp powered 80% of clothing—strong, sustainable, unmatched.
Then, in a blink…
Hemp was sidelined, victim to political greed and propaganda.
Their motive?
Kill hemp, boost profits from cotton, timber, and synthetics–Now three of the world’s most polluting industries!
