Nice when sized correctly
Size: Large, Color: White
I used to be heavier when I started ordering from Amazon, so it’s suggested that I order size “Large”. The following two shirts that I ordered were a “Medium”.
I like the look, and comfortable fit.

Fit: Okay, Material: ...Sensory nightmare
Size: X-Large, Color: Black
I actually love how the shirt looks, the fit is long but I'm a pretty short girl.
One con that ruined the shirt entirely for me though is the material... It's grabby and not soft at all. I wanted a cute athletic turtleneck that would be breathable for a hot work environment. This is NOT it.. it immediately suffocates the skin. Sorry, I just didn't like it.

Super soft, runs small, long tail
High quality, super soft, good neck height, nice price, ready to go right out of the dryer, medium thick material, works well under a sport coat or sweat shirt, snug fit--runs about one size small. Length is about four inches too long. So, ideally made for tall and skinny people (I am short and thick), but going one size up works fine for me except have to tuck it in due to the length.
