UndrDog pairs the incomparable toughness of hemp with the natural airflow of bamboo. You get a tee that is rugged but light, keeping you comfortable in any situation.

Both bamboo and hemp are naturally antimicrobial, so they fight odors, and their moisture-wicking build draws sweat off your skin and lets it evaporate to keep you dry. There are no synthetic chemicals involved, only natural performance.

Yes. Launder and dry it the way you would any ordinary tee, with no special care required. The fabric stays durable and keeps its shape through repeated washes and low-heat tumble drying.

DuraFlow™ is a patent pending breakthrough, the first blend in the world to join the strength of hemp, the airflow of bamboo and the softness of organic cotton.

The tri-blend uses a three-strand structure. That makes it sturdier than a two-strand build thanks to its even tension, and steadier than a four-strand build, where the fibers can work against each other.

That ideal balance secures strength, longevity and airflow, creating the strongest toxin-free tee anywhere, covered by a lifetime warranty. Made for comfort and made to endure.

Hemp brings incomparable strength, bamboo contributes airflow and comfort, and organic cotton supplies softness. As a team they form the most satisfying fabric for lasting wear, ventilation and ease.

Really, yes! Our tees are made to last for life. Should your UndrDog shirt not fit or eventually wear out, we send you a new one at no charge. You only pay the modest cost of mailing it back, and we take care of everything else. This is how we stand behind our quality and keep you protected.

Hemp and bamboo together resist creasing on their own, so your shirt stays crisp through a long day or a cycle in the washer. The fibers keep their form, which means no ironing and no smoothing out wrinkles.

100% sustainable. Every material is organic and kind to the environment. UndrDog stands firmly against toxic chemicals, microplastics and unsustainable methods. Its hemp, bamboo and organic cotton mix keeps the footprint on the planet small, and gives you a shirt that is good for you and for generations to come.

To change how men view what they wear. UndrDog sets out to make the toughest, most comfortable shirts anywhere without giving up on sustainability, health or performance. The mission is to hand men a durable alternative to cheap fast fashion, with stylish, eco-minded shirts that last.
