We do carry select Men's items in size 3XT, 4XL, 4XT, and 5XL. You can view these options HERE by using the size filter feature on the left hand side of the page. We also have a few women's items in sizes 1X and 2X as seen HERE.
Please know that we are constantly monitoring and implementing new sizing on our products, so this may be something that we will expand in the future!
