Love it! John, thank you so much for the kind words and great endorsement :)

  • Daddy-o
  • Crew neck tee

Found these shirts about 3 years ago. Now I hardly go a day without one on. They’re the perfect base layer for colder weather, and they work great with a pair of shorts in the summer. They’re great quality, they fit beautifully and they’re made in USA. What more could I want??

-- RibbedTee Response --
We agree Daddy-o! Our CoolWear Supima undershirts check all the boxes :) Thank you!

Great shirt, second one. Stays tucked in and fits nice and snug. Wish Y'all made it in heather gray!

Thank you Matthew! Stay tuned, because we will soon be releasing a light grey version of our CoolWear Supima Undershirts :)

  • Ken
  • Very happy

Great shirt (says undershirt but I wear it as a shirt). Nice and soft, and the ribbed texture gives it a bit of a distinguished look. You'll look good and feel good wearing it. :-)

Yeah! That's music to our ears Ken!!

  • Dawn L.
  • Works great

My husband loves these Ts. They fit well, feel comfortable and wick up copious amounts of sweat. He looks cool and well groomed, hooray!

Thank you Dawn! We're so happy your husband is looking & feeling his best :)

  • Marc
  • Great fit an feel

Ordered many of the CoolWear shirts over the last couple years, both V-neck to wear with shirt but no tie, and crew neck for the tie and jacket days. Shirts fit comfortably close, like a second skin. They are snug, but so soft that you barely notice they're there. My previous standard cotton undershirts seem bulky in comparison so I started to phase those out more quickly than I had originally planned. The CoolWear shirts have maintained their shape over numerous wash cycles and I haven't had to replace any yet due to wear and tear. These were definitely a great choice.

Wonderful stuff Marc! We can't thank you enough for taking the time to share your thoughts with us, and are really happy to hear your CoolWear undershirts are standing the test of time :)

  • James
  • Well

Good Points:
1) It fits well.
2) It's one of the most comfortable undershirts I've ever worn.

Bad Point:
1) It is quite thin and light. Meaning that my nipples show through the shirt...

I'm not sure if I'm alone on the bad point, as many other seem to love these shirts. However, I still plan to wear this for formal gatherings/business meetings as it is very comfortable.

Hey there James! Thanks for taking the time to provide your feedback on our CoolWear Supima undershirts! They are really great points, and we're happy to hear you enjoy them overall :)

  • Crew Neck review

I like the fit, the feel and softness of the cotton.

Now, that some fine quality H20 John!

  • James
  • Great fit/feel

I bought these after months of looking for new undershirts. I love them, they feel great, fit great and wear well. My only complaint is that as a Canadian they are not yet for sale here. I had to order them from Cal, and pay shipping, and duty, but I would do it again. I wear them daily.

-- RibbedTee Response --
Thank you James! We're working hard to find less expensive shipping options to our friends/Customers outside of the United States. We appreciate your support!

  • Amazing

They are expensive, that's true, but they are worth every penny. Finally an undershirt that works: it's made of smooth cotton, it hugs the body nicely without being constricting, and it's made in the U.S. Please do yourself a favour and buy some. Do it. Do it now.

-- RibbedTee Response --
Yes! Thank you so much Sergio.
