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.
