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.

Bamboo and hemp both possess natural antimicrobial properties that combat odors, while their moisture-wicking design pulls sweat away from the skin and allows it to evaporate, keeping you dry. No synthetic chemicals, just all-natural performance.

Yes, just 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.

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 testicles. Over 20,000 studies confirm the harmful effects. Our tee is 100% free from these dangerous chemicals.

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

The tri-blend design features a three-strand structure, which is stronger than a two-strand design because it provides even tension and is more stable than a four-strand design, where fibers can conflict.

This perfect balance locks in strength, durability, and breathability, making it the world’s strongest toxin-free tee, with a lifetime guarantee. Designed for comfort, built to last.

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.

Yes, really! Our tees are built to last a lifetime. If your UndrDog shirt is the wrong size or ever wears out, we’ll replace it with a brand-new one, free of charge. All you need to do is cover the small cost to send it back to us, and we’ll handle the rest. That’s our commitment to quality, ensuring you’re always covered.
