I really like this shirt. As with many FR shirts, it's a little on the heavier side regarding the fabric. It gets a little warm on hot days, but the material quality is definitely top notch. This isn't a shirt that will last only one season.
My only gripe with it is that the sleeve cuff is a little narrow for the size ordered, and there is only one button instead of the typical two. If there is any shrinkage, it definitely won't fit my wrists. I make sure to hang dry it just in case.
