The fabric of these short sleeve shirts is thin and see-through making it hard to wear them without an undershirt... While they claim to be comfortable, the stiffness of the material suggests otherwise. On top of that, the sizing is off and it's hard to tell whether you're getting the right fit. The only positive thing about this product is the range of colors available, but thats hardly enough to make up for the low quality. Save your money and invest in a better Men's Fashion brand..
