Really a comfortable shirt. The material feels light and the fit is great. I liked that they are easy to keep tucked and don’t billow or wrinkle up at all.

These are the only undershirts my husband will wear. I first bought them for him in 2016 (it's now 2022). They have held up incredibly well over 6 years, and I am only now replacing them as the armpits have understandably greyed - though not nearly as fast as others have in the past. Would highly recommend them! Also great that they have a tall size - my husband is 6'6" and very skinny - these fit him perfectly.

Love these shirts for work or play, I wear them every day.

Last year, I ordered two UnderFit crew t-shirts. I was very pleased with the material and the fit. Unfortunately, possibly through my fault and using the wrong cleaning solutions, they became a bit discolored after washing them. In contacting the company, Leigh McKenzie, was very responsive, engaged me in a conversation and provided me with an opportunity to try another two pair at a bit of a discount. In fact, she responded to my emails late at night, over the weekend and on a holiday. Now that is customer service!

Great shirts and great customer service. I ordered 3 v-necks and got 2 V-necks and a crew sent to me. As soon as I reached out to customer service they responded by sending the 3rd v-neck. The shirts are very comfortable and stay tucked in all day. Definitely will buy from them again.

I struggled for years to find the perfect undershirt, this might be it. The cut of the V-neck is just right to wear with an open collar. The fit is perfect, not baggy but not too tight either. I love the fabric. Soft to the touch and seems to stand up to multiple washings so far. Very happy with these shirts.

I ordered five v-neck shirts for my husband. They seemed fine, but he preferred a crew neck style. I attempted to contact the company multiple times through the email address they provided, but they did not respond. You can't have a company without customer service. Their "no questions asked" return policy seems to mean that "customers may not ask any questions or return items." Very disappointed. Updated six months later: The owner of the company has contacted me and has offered explanation for the lack of communication last fall and plans for moving forward with more attention to customer service. I am hopeful that this will be the case for all of their business going forward.

Love these shirts. Instantly notice the difference in sweat-wicking, dry and cool feeling. I was getting sweaty pits at work with other shirts. Not any more. That’s what makes it absolutely worth it for me. I usually wear size S in men’s clothing. Sized up to M for these which was just right.
