1. learn your skull shape. big and round? or big and long. they make different hats for each head shape. if its big and wide don't curve your brim. if your head's big and narrow curve your brim and it will fit bigger.
2. pay attention to brim width when buying hats.
3. fitted caps. custom, or a company that specializes in hats for big heads if you're much bigger than a 8"er.
4. hat stretchers can get you an extra size or two, and can stretch back hats that shrunk from washing/rain/etc.
5. flexfits in max size. that chinese off-brand that starts with a y is really good too, maybe better.
