Large WW helmet
 

Pete,

Have you checked out any ice hockey helmets? Check out the Bauer HL 4000
model. Excellent impact ratings and they are adjustable to some degree.

Good luck!

Whoops. Forgot to add you would be wise to retrofit the chin strap with
webbing and triglides (easily done). The one it comes with is less than
desirable.
