I like the design and the material, but for the life of me I can't figure out how they rated the sizes.  I bought a 5XL cuz I'm a big guy.  I also bought a 4XL of another company's shirt.  Get this: the 4XL of the other company's shirt is BIGGER than the 5XL from this company!  Unless they decide to correct their size ratings or start making a 7XL, I'm not buying another one from this company.
