- 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.

    Comfort and warmth

    I purchased three of Fresh Clean Threads thermal long sleeve crew neck tees recently. I live in rural Maine and was looking for a thermal layer to help me get through winter. I found the right product FCT makes and sells the perfect answer to staying warm and comfortable on these cold days. The fit is perfect too!!
