No, I'd stay away from online hats (as well as for boots - same issue - never can fit them). I ended up with Troxel Orion. It's comfy, but just doesn't look western.
I'm sure people at the show going to roll when I'll show up! :P
It's a nice one you could find on-line. If it would be somewhere around (even with some further drive), I'd try for sure.
