On Hanes.com, if you use the search tool to search for items in your size, it pulls up items that are *manufactured* in your size, but that doesn’t mean they’re available in your size. For the sweatpants James wants, all they had was XXXL.
Have you tried eBay? Or Amazon? Both places sell new items, and I’m sure you could find some Hanes in your size. Or the Jameses.
