I'm 5'7", 175 pounds, broad shoulders with a wide V-back. I ordered size xxl and it fits perfectly, fits four times over the shoulders and chest but doesn't fit that well in size. Stomach. I work outside under the hot Phoenix sun. Much cooler than cotton and wicks sweat for a cooler feel. Many of my colleagues asked where I bought the shirts. I recommend them if you work in the heat.
