SNS Herning's oldest knit pattern dates back to 1931 with this heavy weight turtle neck. I recall touching on the subject of the long neck knits last winter and now I can't help but return to the topic. While I don't personally know somebody who regularly wears a turtleneck, I have to note that most females I know (my mom and girlfriend) do like them on guys and the comments are usually positive. I've noticed Monocle's fashion director often includes them in their fall spreads and the result is almost always appealing. I think an important feature of a wearable turtle neck is having some sort of texture or knit pattern. A thick cable knit or something dating back to the past of Denmark like this would be ideal. I also think it shouldn't be too slim in the body and rather promote a cozy, casual look while still fitting under a sport coat. It's not an easy one to pull off, and really not an easy item to find in the market.
