The fit of this shirt is as expected, so size 4XL. I'm a big guy and I have room in it. The only thing I can complain about is the sleeves, they wear them loose on the wrist and don't fit like they used to, so I don't like it, the sleeve length is good, the material is light, good for a 50 -degree morning when the temperature drops to minus 70 degrees in the afternoon, overall I like this shirt and it fits well
