Soft and comfortable, Quite long for me (I am 5'8") so I need to fold it under when I wear it over my gym shorts. I would like it if you also offered a heavier fabric for winter, and long sleeved as well.
Thanks, John Schroeder

Thank you John! We'll be sure to share your feedback about heavier fabric for a winter undershirt, as well as a long sleeved version, with our Product team.

  • Undershirt

Great slim fit with length that is often lacking in other t shirts. Very comfortable to wear. Really trying to buy items made in the USA, so this purchase works on many different levels.

Great fitted t-shirt. I’ve worn and washed it numerous times; holds its shape.

Appreciate that Patrick! Thank you very much :)

  • wish they were thicker and not so tight fit

Wish these shirts were made thicker like the old Gap style and also less tight fit. Not everybody has the body, that can wear the tight fit versions. I am looking for just cotton, not the spandex'ish style.

  • Great Quality, hoping for wider crew neck though

The quality and feel is supreme however the crew neck shows under my tee shirts i was hoping for something more subtle. If you have a product that is wider around the neck so i can wear wider crew neck teeshirts that would be great! All in all the ribbed tee does its job supremely. But cosmetically needs a little wider crew neck.

Thanks for that feedback Jake. We will certainly share your comments with our Product staff. Enjoy!

  • Andrew Kuti
  • Great stay tucked shirt

Tried these for the first time about a month ago. I was tired of retucking my shirt ten times per day with standard under shirts. These do a great job and after five washes, still stay tucked and fit great.

-- RibbedTee Response --
Nice! Thanks so much Andrew. We're happy you're enjoying out stay-tucked undershirts :)

  • Quincy
  • New undershirt

I had been looking for a new brand, fit and feel of undershirt to wear (as I move away from “wife beaters). I came across this product by doing some online searching and MAN am I gald that I did. The shirt feels amazing and I love the way it fits. I bought just 2 at first to try and now I am all in. If you are looking for a new, better feel give these a try.
