The material is very cheap and transparent. I ordered L and XL in the same red and both were completely different shades of red. One was very light, the other more burgundy. All of this to say that I really like the fit, most "muscle shirts" don't really fit like muscle shirts, more like traditional shirts. Belly too big, not enough arms or chest, too deep. This one got that part right. I probably won't order more, but I'll keep the XL. XL is my normal size, so the size fits me perfectly.
