Aka–Plastic. We compared them all to the one brand that doesn’t.

What’s In Your Shirt?
Not all “premium” tees are made equal. Here’s what’s actually in them.
- Primary Material
- Secondary Material
- Plastic Content
- PFAS Chemicals
- Microplastic Shedding
- What’s on your skin
Every Internet Tee Brand

Spandex - 60-90%

based synthetic plastic
UndrDog
Hemp
- Hemp - Earth’s strongest natural fiber
- Bamboo (Natural
Plant Fiber) - 0%
- Zero. Completely
PFAS-free. - Zero. No Plastic
To Shed. - Plants.
That's it.
Check the tag on any of them. Polyester is right there. Polyester is plastic.
That's not an opinion - that's what the material is.
Here's Why That Matters
Polyester is a plastic made from petroleum. This is not debatable - it’s what the material is.
When you sweat in polyester, plastic fibers sit directly against your skin — the largest organ in your body.
When you wash polyester, it sheds microplastic particles into the water. Studies have documented this extensively.
UndrDog uses Zero Polyester. Zero plastic. Zero PFAS chemicals.
Just hemp, bamboo, and organic cotton - combined in our patent-pending
DuraFlow™fabric technology.

What researchers are finding:
How Does It Actually Feel?
Patent-pending DuraFlow™vs. synthetic wicking that traps heat.
- Airflow
- After a workout
- In the heat
- After 50 washes
Every Internet Tee Brand
- Synthetic wicking moves sweat but traps heat
- Wet, clingy, smells
- Sticks to skin,
holds sweat - Pilling, thinning, stretched
UndrDog
Hemp
- DuraFlow™bamboo micro-gaps create constant natural airflow
- Dry, free, no odor
- Feels like wearing almost nothing
- Softer, stronger, same shape
DuraFlow™works because bamboo fibers have natural micro-gaps that allow constant airflow. It's
not a chemical coating that washes out. It's the structure of the fiber itself. Patent-pending.
How Long Does It Actually Last?
You're replacing those tees every year. That's by design. UndrDog is
built to never be replaced. That's also by design.
- Stretches out?
- Holds odor?
- Pit stains?
- Average lifespan
- In the heat
Every Internet Tee Brand
- Yes - loses shape after
15-20 washes - Yes - bacteria clings to
plastic fibers - Within months
- 6-12 months before replacing
- 30 days, maybe
UndrDog
Hemp
- No - hemp gets stronger
with every wash - No-bamboo is naturally
odor-resistant - No
- Lifetime warranty
- Lifetime. Literally for life.
How Does It Actually
Look On A Real Guy?
Most internet tee brands are designed for the guy in the photo. The model. The 6'1"
guy with 12% body fat. UndrDog is designed for real men.
