Company details

  1. Men's Clothing Store

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.

Not worth cost

After the first wash there are a bunch of vertical lines a rossnthe shirt like the fabric is stretched or broken. The second shirt did not have the same thing happen. They are also not true to size, seem much smaller. I was hoping since made in USA it would be comparable US size but it is much smaller than other tees of same size. Too expensive for a shirt that breaks down after first wash and is not true to size.

The shirts are comfortable so far

The shirts are comfortable so far. They did get shorter after a wash, not sure if I like such a short tee.
I'm definitely not a fan of having to subscribe to Instagram to enter any giveaways from UndrDog, I don't use or have that app.
Thank you.

good but not long enough for a tall guy

I like the shirt but I feel they are too short.

I am a tall guy 6'3" and ordered the xxl.

The shirt is significantly shorter than other xxl shirts I own and like to wear daily.

I do like the quality of the shirts.

Good

Good, high quality shirts. Just be sure not to put them in the dryer. Hang to dry only, otherwise they are prone to shrinking. I had to exchange for a size up after I used the dryer initially 😅

Wasn't a fan of the fit too loose

Wasn't a fan of the fit too loose in the arms(I even have larger than average arms) and way too loose in the belly. I purchased the xl as i normally wear xl in everything. Im not going to take the time to try a large. Just wasn't the right fit for the price.

I really wanted to love this shirt

I really wanted to love this shirt, but I can’t figure out the sizing, there chart said I was a L in other shirts I order XL I ordered XL. The shirt was too short, the sleeve were too short even though the seam was off my shoulder. The shirt also felt like it was on backwards. Material is rough might feel better after several washes There return process is very good my congratulations on that part. Order XXL length is better sleeve length is good but seams way off the shoulder fits like a Carhartt now. They will be good to sleep in but not go out of the house in. My suggestion and I know you are just getting started so improvement will be limited. Wash the fabric before cutting the shirts so it won’t shrink any more. Fire whoever made the sizing templates. Size them like Dickies tee shirts something for regular people, go with a raglan sleeve so it will work for everyone. When established branch out into different styles for different body types. I think the product idea is great just size them for the regular guy.

Quality T-shirts as advertised

From reviewing Trustpilot positive reviews to the order process and ultimately receipt of three T-shirts I am very happy with Undrdog Hemp. These are definitely the most comfortable T-shirts I have ever worn. They are so comfortable that I have slept in them for several nights. I am looking forward to seeing what other colors and ultimately what other style styles. Undrdog Hemp will release. These are premium T-shirts meant to be a foundational part of a man’s wardrobe, as well as last a lifetime I will be a regular customer if this experience continues to be positive.

The fit isn’t great

The fit isn’t great. They are short and have shrunk which made things worse. They compare themselves to BYLT but those shirts fit are superior to underdog. I tried them but wouldn’t buy more.

No BS.

I've been on the fence about trying these out for some time. I could tell immediately that this wasn't like the usual P.O.S. undershirts I've been buying all of my life. I will be ordering more of these soon.
