Nice shirt.
Color: Black, Size: XX-Large
Good neck height, not too high, firm neck grip without the choke feel. Clean look when wearing under an open shirt or looks good alone, Soft feel against the skin, and it washes well, no pulling or color fade. semi-form-fitting on the body, but not tight for the size. priced well.

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.
