How This Breakthrough Hemp & Bamboo Tee Helps Thousands of Modern Men Stay Cool Without PFAS Chemicals
FOR THE PAST 5 YEARS, THE FAST-FASHION INDUSTRY HAS PROFITED FROM CHEAP TOXIC SHIRTS THAT NEED REPLACING EVERY 1-2 YEARS
A young founder of a trending startup company saw that the $38.3 billion t-shirt game was broken, so he fixed it.
His company, UndrDog Hemp, discovered an innovative blend of non-toxic fabric to create the world's strongest shirt with a lifetime guarantee.
With over 5,000 independent studies1 linking cancer, infertility, and reproductive issues to PFAS 'forever chemicals' and microplastics, UndrDog Hemp is rapidly becoming the most sought-after men's tee for 2025.
How Did They Do It?
About UndrDog Hemp
The company initially aimed to create an affordable, eco-friendly Hemp Tee for Men focused on durability, breathability, and comfort.
Also, a shirt that would last longer than a mortgage, saving men $200+ per year on cheap cotton tees that need replacing every 1-2 years.
Their first prototype was 55% Hemp and 45% recycled polyester, and it was a big success!
Until…
The Wake-Up Call
Their founder was researching 'infertility' after 4 years of trying to have a baby with his wife.
That's when he discovered that microplastics in polyester clothing were linked to infertility.
Specifically, the PFAS chemicals it contains are linked to cancer, birth defects, and a host of other health problems.
Studies2 show wearing polyester leeches toxic microplastics straight into our bloodstream.
Thousands of experts worldwide are reporting a growing list of serious health problems linked to PFAS and microplastics, including:
-
Cancer
Increased risk for liver, kidney, and testicular cancer.
-
Shrinkage
In male appendage 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.
-
Respiratory
Linked to asthma, lung damage, and chronic breathing issues.
-
Birth Defects
Linked to preterm birth, low birth weight, and developmental delays.
The Pivot
He had a choice: keep selling toxic shirts like everyone else or fix it. He chose to do better.
The company's new direction was simple. How to make a strong, breathable and comfy shirt with a lifetime guarantee–WITHOUT toxic PFAS
forever-chemicals.
Bamboo fabric is known for its softness and breathable airflow.
The only problem was that there was no technology for blending Hemp with Bamboo successfully to meet the UndrDog "Lifetime Shirt" standard.
So, they created the technology.

Absolutely. The DuraFlow™blend of hemp, bamboo, and organic cotton creates a midweight shirt with a higher GSM, designed for ultimate comfort. It's breathable, soft, and fitted to enhance the male physique, gripping the body in all the right places to keep you feeling comfortable all day.
How can it be breathable AND durable?
UndrDog combined hemp's unmatched durability with bamboo's natural breathability. The result is a shirt that's tough yet airy, so you stay comfortable no matter what.
What makes it odor/stink-free?
Bamboo and hemp both have natural antimicrobial properties that fight odors, while the moisture-wicking design pulls sweat away from your skin and allows it to evaporate, keeping you dry. No synthetic chemicals, just all-natural performance.
Just normal washing and drying?
Yep! Wash and dry it like any other shirt. No special care needed. The fabric's durability and shape retention stay strong, even after multiple washes and machine drying on low heat.
Why is "No PFAS &Microplastics" important?
PFAS and microplastics are proven toxins that never break down. Studies show they leach into your skin, bloodstream, and organs, increasing the risk of cancer, infertility, and even shrinkage of the penis and testicals. Over 20,000 studies confirm the harmful effects. Our tee is 100% free from these dangerous chemicals.

DuraFlow™is a breathrough patent pending technology, and a world-first blend of hemp's strength, bamboo's breathability, and organic cotton's softness.

This perfect balance locks in strength, durability, and breathability, making it the world's most strongest toxin-free tee, with a lifetime guarantee. Designed for comfort, built to last.
Why this blend—hemp, bamboo, cotton?
Hemp gives unmatched strength, bamboo provides airflow and comfort, and organic cotton adds softness. Together, they create the most satisfying fabric for durability, breathability, and comfort.

What makes it wrinkle-free?
