The products so far are excellent and live up to the hype and branding, surprisingly. The biggest issue I have are the extraordinarily long ship times. I understand these are batch orders that are be... See more

Written by the company
UndrDog is more than just a shirt. It’s a statement against everything broken in the apparel industry. While most shirts are made with plastic-based materials like polyester, UndrDog is built from plants, never plastic. Each tee is crafted from our patent-pending DuraFlow™ fabric: a high-performance blend of 51% hemp, 31% bamboo, and 18% organic cotton. It’s breathable, durable, and completely free from PFAS, polyester, and microplastics. UndrDog’s mission is simple: fight back against the rise of plastic in clothing. Polyester doesn’t breathe, traps heat and odor, and sheds harmful microfibers into the environment. Our DuraFlow™ fabric does the opposite. It wicks moisture, resists odor, holds its shape, and lasts far longer than typical cotton or synthetic blends. Every shirt is cut with a tailored athletic fit, gripping high across the arms and chest, and loosening slightly at the gut for a more flattering silhouette. You can wear it hard, wash it often, and still expect it to hold up. Whether you're working, traveling, or heading out, UndrDog is built for daily wear. It’s not just a better shirt, it’s a better standard. And it comes with a lifetime guarantee to prove it.

Order took longer than I thought it would.
This second tshirt was a Christmas gift for my second son. I used the 5.00 gift certificate from the first order for another son. It was issued as an apology for that tshirt shipping length . The second tshirt was shipped faster but still not super fast and I received another coupon for 5.00 for that.
If they are going to give you 5.00 off as a reward for ordering and waiting for the order to arrive, why not just knock 5,00 off every tshirt that is ordered?
My boys say the t’s are comfortable but they have not been raving about them but it’s only been about a month since they’ve received them.
It’s just such a great shirt

Great T's
I tried several of the over hyped popular cotton/poly blend T's you see all over social media. I'm retired, so t-shirts are my daily go-to. All the cotton/poly shirts just didn't seem to last. I bought a 3 pack in December, and was impressed enough to order 6 more this month. How can you go wrong with a lifetime guarantee?
True to their word, exchanging size was a breeze
I got my usual size and found it was too large. UndrDog was great, happy to exchange for another in the next size down and they handled the shipping back and shipping out a new one, all for $27.
Great quality and looks sharp!
These shirts are well constructed and look very crisp and flattering on an athletic build. My husband loves the feel of the material. It's thick but not overly hot. There's a minute pattern in the material that makes it look very polished- much nicer than a regular t-shirt.
Well-made and comfortable.
As advertised!!!
I like the feel of these shirts. I just received my order of 3, and can’t say much more about them since they are so new, and I haven’t got to wash them yet.
Well I had three people come over to me and tell me I looked great, and liked the shirt. I told them Underdog hemp. So they do seem to make the dad bod, or in my case grandpa bod look good.
Update 01/15/26: after washing them they did shrink a tad, if only lengthwise. They still make my grandpa bod look better 😉
Hidden return fees!!
My review is about the company more than the shirt. The shirt wasn't what we were hoping for, sleeves are too long and fit was snug in some places and looser in others...but what the site doesn't tell you when they guarantee the shirt is that it will cost you $10 to return it. To me that is sneaky marketing and if you aren't upfront about your practices, I have to wonder what else you're hiding.

I have tried to contact them via email…
I have tried to contact them via email and it comes back as unavailable. I have tried to contact them via phon.e It’s ALWAYS a busy signal.
I’m stuck with three Small (expensive!) t-shirts when I ordered XXL’s. So much for this Christmas present…..
Stay away!

Stout
Just received the shirt. Looks good and stout as advertised. Looks like it will wear well.
Ever lasting and organic tees! 1930 military-grade textile! OMG! This is what i was waiting for the last 20 years all
I just went and bought 6 tees for my self only 50$ CAD each promo price, for super dupper durable black tees. I got Large in size. Now hear me out, its important to understand the science of the material. When fresh out of the bag, the tees seem a little big... im a 210, 6 feet, average in size, (doctor says i am obese, fu.. off Doc, i got 3 toddlers to support, doc, i dont need the negativity..). Anyway, once wash it fits snug, little tight even, BUT IT WILL shape to your body and fell comfy after like 15 - 20 min. The material shapes to your fit, i promise that. This is what i ve been waiting for, a sustainable apparel made with alternative natural material. Garbage nylon and polyester, petroleum base crap! No more of that. I use these tees for workouts, trades work, cozy home outfit even casual going out evenings! The GF digs the biceps, love the guns! Lol. Wow, good work guys!! I will share and purchase more in near future.
AWESOME SHIRTS… excellent customer service!
Nothing but great things to say about the UndrDog team. Had a small issue with an order… they fixed it quickly even over the holidays! The ONLY disappointment is that I missed out on the Red shirts.
I will have 9 midnight shirts in just a few days and apparently the only nine I will ever need! Keep on keep’n on! The whole UndrDog Team is doing an awesome job!
What great customer service
What great customer service! My shirts didn't fit, they sent me return label right away and my new shirts were on their way the next day.
Order Correction
I made a mistake on my order dated 31 December 2025. I sent an email asking for a correction on my order. Within hours of my order the same day UndrDog Hemp responded with a correction and refund for my order. I look forward to UndrDog Hemps future products.
