Akubra has an excellent reputation on the Fedora Lounge. The Federation IV is the fourth generation of Indiana Jones styled hats. Check your size at a hat store before you order, these are from Australia, and shipping ain't cheap. These are 100% rabbit fur, no wool, and are styled very close to the movie hat. They sell two colors of gray, Charcoal and Moonstone.
