Great Shirt, but a bit Heavy
Size: Large, Color: Black
Very comfortable shirt and good quality. My only gripe is that the material is a bit heavier than I'd like.

Loose fitting neck, not snug.
Size: XX-Large, Color: Dark Blue
I am 6’4” weigh @ 230 lbs and ordered a 2XL. My dress shirt neck size is 17 inches. If you’re happy with a very loose fitting around your neck, then you’ll be ok with this mock turtleneck shirt. I ordered thinking it would be a snug fit around the neck size, not hanging down @ one inch or more in the front.
