2 sizes, small, and large however, the large is not "large, it's normal, 24"..
These were supposed to be for display purposes only however, When I owned 3, 2 fit on my head and 1 didn't. I emailed Lee and he mentioned that a few came out larger than others un-intentionally...
So, there were 2 sizes but that wasn't the plan..
Hope this helps!!
Thanks for the SWEET sig. Drew!
