Read the size chart. I'm 5'7, 184 lbs, athletic build with a 39 chest and 33 waist at the belly button, wearing a small. Shoulders are a little narrow but the rest of the fit is great. Arm holes end about 3 inches from the crease of the elbow.The fabric is moisture wicking and breathable. There are pen pockets on the left shoulder, which are a little silly is you ask me.The vent panels on the sides are just for show. They're the same fabric as the rest of the shirt.
