Do you remember if that HJC was a CL-12? That's what I'm currently running in 3XL. It was snug when I got it but after three seasons it's a bit sloppy. I've tried on some 3/4 and 1/2 helmets in 2XL and they seem to fit okay, but I wanted the full face helmet.
Keep up the search, you'll find something eventually.
