Fits true to size.  Quality is excellent, especially for the price.  If this shirt lasts half as long as my Columbia shirts I will still be money ahead.  I'm hard on my outdoor clothes.  I wear them hard and get them filthy.  I swim in them, work out in them, work in them- whatever.  I use them for sun protection as much as anything else.  This shirt material feels great and the seams look good.  I'm impressed.
