Ordered out of sheer curiosity. I've only worn it once for a few minutes just to see how it looks. I'm 6'4, 215, medium/light build. I have a middle aged small belly. I can greatly improve the look of my upper body by sucking in my stomach and sticking out my chest. This shirt more evenly compresses the belly fat around my waist and flattens it with the rest of my torso. It makes me look a little thinner. However, belly fat can only be pushed so far away from the stomach. Perhaps this shirt will give better results for taller men. As for me, I can't say I benefit much from it. Not good enough to wear that.
