“These are the best t-shirts I’ve ever worn. I wear them daily - not as an undershirt but as a shirt. Fit is great, color is great, and they really are flattering.”

- Dave S.

"Great fit great color the tee is soft and feel great I have ordered and received 6 tees so far I love them."

- Melvin B.

- Dan S.

- Shauna S.

"Got one just to see if I would like it . I do... Soft, comfortable and looks nice with shorts or jeans. Will get another one."

- Cheryle K.

    Hi Brian, we’re sorry to hear those sleeves are coming up short! Since the cut of this specific tee isn't working for you, we’d love to help you find a better fit—like our Tall sizes which offer a bit more room. You can set up a free exchange or a full refund right here: https://returns.freshcleantees.com. We want to make sure you're taken care of!

    Best winter thermal available anywhere

    I love these long sleeve thermals. I bought my first one 2 years ago for the cold Western New York winters. Quickly became my favorite go to shirt. Very warm and comfortable, great under a hoodie. I now own 7 of them. You can't have too many of these awesome long sleeve thermals. You can put me in the dirt wearing one of these things, when the time comes of course.

    Pretty good

    Overall, it's a nice thermal. The reason I did not give 5 is because while it is comfortable, it is not as soft as the other FCT shirts I have, or other thermals I have worn in the past. Also, it does not stretch very much. I like to bunch the sleeves up, and it is very tight and I can barely move them up at all. In the end, I would buy another one, but I'm not lining up to replace my whole closet with them.

    Hi Justin! Thanks for being a longtime fan of our threads! We appreciate the honest feedback on the thermal's stretch and softness compared to our other shirts—we'll definitely share these notes with our product development team. Glad to have you in the crew!
