High quality shirt but, runs very small in size!

The shirt is a high quality material and very nice. The only criticism I have about this shirt is the size runs very small. I purchased this shirt in an XL as a cooling shirt for work, I like the wicking shirts and allows your skin to breath better on the hotter days. The shirt is very well made, nice hems, not loose and the material is very good quality. I had to give my son the shirt because the XL size is actually a medium to small large, disappointing. I would highly recommend this shirt but, know the shirt runs very small.
