I really like this shirt...great colors, looks very nice and keeps you cool.  The sizes run quite large as I typically buy a size large in a standard polo-type shirt but I purchased this shirt in a medium and it still is very roomy with shoulder seams off the shoulders a bit.  I could fit in a small but prefer the looseness for air flow.  That aside, the material is very smooth and the style looks sharp.  I have purchased several.
