“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.

Nice Shirt

Material is soft. It is thicker than a tee, but thinner than a sweater. Shirt fits well all around. Sleevs are a good length. Will keep you warm in cool weather above 50 degrees. If it's less than 50 degrees outside, you will need a shirt underneath or jacket over it to stay warm.
