Nice shirts for the price! But do not recommend for thick body types.
I bought 3 different ones. 2 Mediums and 1 2XL. The mediums fit correct and really nice! Would definitely recommend for the price! More like a exercise material, and sticks to your body shape... Sooo the 2Xl did not fit the person correct. Was so tight... And the strech is to stick to your body... So would not recommend for anyone a bit hefty or fit tbh. But the shirts are good materials and feel nice for a fresh day out or to use as gym clothes!!

Great Value heat gear material with high neck collar and loose fitting
Color: Black, Size: X-Large
My husband has been looking for mock neck shirts that are comparable to UA heat gear material but that are short sleeve and fit loose to wear under his work uniform. These seemed to have been a good soft quality option and the price is is great.

Color: Navy, Size: Medium
I bought the black T-shirt about a month ago and really liked the quality the fabric is soft, the fit is great, and it holds up well after washing. So I decided to get the same one in dark blue.Very satisfied with the purchase

Fit me even better than I was hoping.
Size: XX-Large, Color: Beau Blue
I was all but convinced upon receipt I would be sending these back but they fit beautifully. The trick is understanding what the directions are trying to tell you.
I’m 6’4 with a 40 inch waist on traditional jeans (regular fit). I selected 2XL because my feeling was I would want and need a waist line that would fit me but not constrict me.
Admittedly my regular fits were getting close to not fitting as good anymore so I felt 2XL would give me that “extra” my regular fits were no longer affording me.
Comfortable at the waist(not too tight) and they fit me nicely all over. Perfect length. Colors look great too. The pictures shown are accurate. I’ll be ordering more. Give these a try! Definitely worth the money.
