I bought the navy mock turtleneck. On the web site it looks like a nice medium navy, but in reality it is very dark, and hard to tell from black. The quality is not bad, but not super heavy weight...
This shirt is more than advertised, it is warm, comfortable and way too nice to work for work - unless you have an office job. (smile) Quality construction and fit. OK - so I will wear it for work.
