The shirt is a great feel and looks great, but it is listed as a 5xl and fits more like a 3xl.  I am not sure if the company is using a different sizing guide, but this definitely is not big enough for a 5xl customer.

It is a bit sad when larger clients find nice things that still do not fit even though they are advertised as being a correct size.  If you can, try adding two sizes when you order and it may be a great fit. (Writing for my boyfriend for whom the shirt was purchased.)
