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.
