Russian hat size translation to US?

I’m wanting to buy a Russian ushanka from http://www.ushanka.com/product/ushanka-black/. It wasn’t real fur, but, it looks warm and cozy nonetheless. So, in the size pull-down, it shows sizes 54-64. Uhhhhhh…whatever. So, I wear Xl to 2XL. How would that translate to me?

Thanks,
hh

You can translate it by looking at the size conversion chart:
