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.

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.

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.

The hemp and bamboo blend naturally resists wrinkles, keeping your shirt looking sharp after a long day or a trip through the wash. The fibers hold their shape, so you don’t have to worry about ironing or ironing out those wrinkles.
