THE ORIGIN STORY
HE BUILT SOMETHING TOXIC.
THEN BURNED IT DOWN.
Chuckie spent years building what he thought was the world's toughest tee. The first version was hemp-polyester. Strong, but loaded with PFAS.
Then he and his wife Shelby started trying to start a family. He went deep into the research on male fertility. That's when he found the studies.
"The research was undeniable.
I was selling men a polyester tee that could be working against them. So I burned the whole thing down and started over."
Founder of UndrDog Hemp
$300,000 and a year later, UndrDog was rebuilt from scratch. But the problem wasn't only tees, it's below the belt too, where polyester presses against your balls 16 hours a day.
INTRODUCING
COMMANDO
- 18 Months of engineering.
- Every detail obsessed over.
- The product no other brand had the balls to make.
THE FACTS
SHRINKING BALLS.
DROPPING SPERM COUNTS.
THIS IS REAL.
This isn't a scare campaign. It's peer-reviewed science, and a Netflix doc just put
it in front of 200 million households. Here's what researchers keep finding.
Your
Testicles
Microplastics in every human testicle they tested. Not most. Every single one.
(Zhang et al., 2024)
Your
Semen
Microplastics in human semen too, including PET, the exact plastic in polyester underwear.
(Zhang et al., 2024)
Your Penile
Tissue
They went looking inside penile tissue. Found microplastics there too.
(Zhang et al., 2024)
Your sperm count
Men who wore polyester against the testes for 12 months saw sperm count crash to zero. It recovered once they stopped.
(Shafik, 1992)
Your underwear is
60 to 90% polyester. It sits against the most sensitive part of you 16 hours a day.

THE TRUTH
ZERO SYNTHETICS.
ANYWHERE.
Nothing hidden. Ever.
Not in the fabric. Not in the waistband. Not in the pouch. Nothing. DuraFlow™ (patent-pending) hemp & bamboo. No-PFAS, no-plastic,
no-excuses. Protecting the part of you that matters most.
THE FIT
ZERO RIDE - UP
No more adjusting
Freeballing comfort without going commando.
Zero ride-up. Zero adjusting. Perfect flex on
thighs. 140 GSM, our lightest DuraFlow™
(patent-pending).
THE AIRFLOW
COOLING WEAVE
POUCH
Breathes downstairs.
100% breathable organic cotton construction. Keeps your nuggets off your thighs. Insane airflow. Supportive where it counts.
No sweat rash or itch.
THE FIT
TREE RUBBER
WAISTBAND
Plants, not petroleum.
Natural tree rubber blended with the highest quality bamboo. Grown from earth, not in a lab. Most other so-called "natural" boxer brands hide synthetic elastic in the waistband and bury it in the fine print. Recycled plastic is still plastic. We don't compromise.
THE FEEL
SOFTER THAN GOING
COMMANDO
Barely-there comfort.
Machine-softened 51% hemp, 31% bamboo, and 18% organic cotton at just 140 GSM, our lightest blend ever. It's the closest thing to freeballing without freeballing. Gets softer with every wash, never thinner.
THE LIFT
2x bulge zone
No hype, it makes your junk look bigger. We're serious. Roomier pouch plus double-layer GSM construction on the front. Engineered on purpose. You're welcome.
BUILD TO LAST
DURABLE COMFORT
Experts were wrong. They said durability and breathability can't coexist. DuraFlow™
(patent-pending) proved them wrong. They said hemp over 30% is too rough. We machine-softened 51% hemp and blended it with bamboo. Experts talk. We build.
THE LOOK
PREMIUM LOWKEY
BRANDING
You're the hero. We don't need to plaster our name above your family jewels. You advertise your package. We use a subtle raised
tone-on-tone branding. You get the attention.
