It's true to size. I have a 42" chest and typically wear a large. I ordered large and it fits. Grab these while you can as most of these mock neck t shirts are a cotton poly blend. These are 98% cotton. This is important because although the cotton/poly blends dry quicker, they are uncomfortably warm if it gets above 70 F. I have purchased other mock turtlenecks and had my local dry cleaners convert them from long sleeves to short, but they are slightly heavier weight than these. I do wish that they made these in a dark green or military green color.
