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.

Only one minor issue
Color: Haze Blue, Dark Red, Black, Size: Medium
I got these I ran them through the laundry. They didn't seem to bleed at all.
I like short sleeve because when I put a long sleeve on under a shirt the sleeves bunch up behind my elbow and I have a hard time pulling the inner sleeve forward.
My only complaint is there is no neck tag to indicate which side is front and which is the back of the shirt.
