Quality item
Color: White, Size: X-Large
Not too thick and not too thin, the quality is good I just wish the neck fit a little firmer and it would be 5stars

Well made and comfortable
Color: White, Size: Large
The turtleneck is well made and very comfortable. It's good looking too! I have a similar turtleneck (from an unknown maker - tag is missing) that I've owned for more than 40 years. It will likely outlast me!

BO - stinky!
Color: White, Size: Medium
Shirt itself fits great and has a soft almost velour feel to it. Ribbing nice and not itchy. However, it arrived with the most disgusting baked-in body odor smell, as if someone had sweated heavily in it. Unsure if it’ll be able to be laundered out.
