Mock turtle neck sagged and did not fit well.
Shirt is well made. Collar not so much. Sagged and did not fit well. Donated to Goodwill.

A Difficult to Find T-Shirt
These T-Shirts are nice. A super difficult to find. The manufacturer calls it a mock-turtle neck (MTN). But the collar height is actually a bit shorter than the traditional MTN, which is great. It's closer to a regular T-Shirt that comes all the way to the neckline. And very somt a comfortable. This is the perfect style of T-Shirt to wear under a sportscoat, if desired. Or under a shirt where you want the T-Shirt to show for contrast. Just the right look.

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.
