Neck came frayed/cut
Size: Large, Color: White
Poor quality. The collar/neck area was cut up/frayed. Never had a chance to return this shirt in the allocated amount of time. Guess we have an expensive rag.

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.
