This is a nice shirt at a good price.  Ordered 2.  I read some reviews that it fit a little small.  I ordered a size bigger and it was a size bigger.  I then ordered the size I normally wear and that one fit perfect.  Kept the other one for when it cools off in the evening and I want to wear a t-shirt under.  Larger one still a little big.  Collar comes down low.  No issues.  Love the bright colors and quality is really good.
