If you have an athletic build with a slim waist, these shirts are for you. The fabric is very soft to the touch and stretches - so it doesn't feel too tight in the chest/shoulders, while still being slim through the waist. They do not offer the shirts in "Tall", but their standard lengths are adequate for someone like me who is 6'3". The only issue I have is that the shirt's product information is printed directly on the fabric just below the collar on the back. While the printing is on the inside, the grey print can be seen to some degree on the outside of their lighter colors. This might not bother some folks, but just a heads-up. Overall great shirt.
