If that link doesn't work, just go to discoveryparts.com, look up helmets
and go from there.
About halfway down the list is a hybrid model from G-Force -- it's full face
but with a bigger opening for better communication to your instructor.
Talk to Ron -- or anyone else there. Good prices, great service. G-Force
is SA2005 and sells at a lower price point that, for example, Bell.
Alll the best,
