“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.

"These shirts are great! They help give the appearance of a slimmer gut and are long enough that nothing pops out while reaching for anything above shoulder height."

- Dan S.

"Love the fit and material, can be dressed up or be casual. I now have it in 3 colors."

- 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.

"Fit is great. Shirts don’t lose their shape after washing. Nice colors."

- Miranda O.

One word describes what I think of F.C.T, EXCELLENT, Awesome, GREAT, wait, that's 3 words. The feel is fantastic. The quality is amazing, and my overall experience wearing my Tees and thermal 5 out of 5. My new spot for excellent quality gear.

Fits beautifully, looks polished

Found this shirt for my friend and wouldn't think I'd ever describe a thermal as polished but the cut of the shirt and high quality fabric gives you just that: comfort and style. Great shirt, I'll be buying more.

Exactly what I was looking for.

This shirt fits how it is supposed to. I bought mine for a top layer. Soft and comfortable. It will keep you warm. If you want a therml underneath, I'm betting a size down will be perfecy.
