The recurring description is that the shirt moves air rather than trapping it, and that sweat does not show through or cling the way it does with polyester athletic shirts.

UndrDog markets this as DuraFlow™, its name for the hemp-bamboo-cotton weave. The reviews do not verify the specific "300% more breathable" figure the brand uses, because no customer review can measure that. At 4.81 stars across 2,158 reviews they do consistently support the underlying claim about airflow.

Black Tee

I’ve been really impressed on the breathability of the black fabric in hot summer weather!! Definitely does not hold the heat poly/cotton tee’s do. Curiously being in direct sunlight, the tee shirt felt like it was insulating or shielding from that direct heat. It didn’t feel like it was a heat soak. It breathes so well. Awesome product! Looking forward to more items being added…. maybe some shorts or pants? 😁

Great shirt great idea!

Bought for hubby. He has been wearing moisture wicking shirts for his construction company, but smells like a goat at the end of EVERY DAY! This shirt seems to lessen his BO daily. He works hard, and sweats alot! The only sticking point is the price! I wish they could be priced lower, so we could buy them for his crew!

A difference I didn’t know I was missing. I have already ordered more and plan to keep building up my stack until it’s impossible to run out. There is a dryness that comes with breath ability that I honestly didn’t know was missing until I experienced it. The price did cause me to be hesitant but the quality and comfort have definitely been worth my dollar.

I’m an underwear fanatic. I’m always trying new brands and styles to find what works best for me. I’m a blue collar worker that sweats a lot, so I’m looking for cool underwear that stays in place. These do the job nicely. I knocked off a star because the pouch for keeping the jewels in place could use a little work. It’s not really a pouch and doesn’t do its job well. There’s room for improvement there.

Most Excellent shirt!

I wear cotton, merino, alpaca, bamboo, hemp and other natural fibers. This unique combination is unbeatable and such a cool name. From the moment I donned it I could feel it was different. It was substantial and solid, yet oh so comfortable. It is my go to shirt, at least until my other colors arrive! Thanks UndrDog! The Edoda Yona

I’m 6’1” 210 pounds. I bought both the large and the XL. The large was better fit. I don’t love the length. A little too long. And it flares out just a bit at the bottom which I also don’t love. I like the over all feel of the fabric. And I like the fact that it is chemical and plastic free. It does seem to breathe better than most of my other shirts so that’s a win for hot Austin weather.

Product underwear

Soft. Did shrink dye lots out with hand wash. Shrink from washing in machine. Second order hand washed. Dye a lot in sink. Also tecticules feel hot. And damp. Considered about dye on them. Xl. Probably need to up size. Waist is 38. Not really crazy about them. Will see what happens. Maybe need white ones with no dye. Little concerned now. Any ideas. Rob Haneisen

Black and white t *****

Bought six black and white XL shirts. After the initial time wearing them, I washed as prescribed for the materials. They shrink quite a bit (2 inches from collar to bottom of the shirt). The material is thicker than other shirts, but very breathable. I was comfortable in 90 degree weather. The shirts didn’t soak like cotton. I like the material, but should have bought the next size up.

Uncomfortable

The fabric is way too stiff and uncomfortable, especially in hot states like Texas. It feels like wearing sandpaper against your skin. The fit is also very strange and unfortunately just didn’t work for me. On top of that, I had to pay $10 to return the shirts. Overall, not worth it for the price. Too much marketing, but the actual product and return experience were disappointing.
