Although they use XL sizing, rather than XB, Nautica are similar in fit to Canterbury or RM Williams, but possibly an even more generous fit than those brands. They are also pre-shrunk prior to construction to minimize shrinkage. So if you are normally a 3XL in other brands, we highly recommend you select a 2XL in Nautica (ie down one size from a brand that normally fits you)
