SPH4B from Helicopter helmets in Hartford Conn. $700 + change. Oregon aero hush kit + zeta liner, I'm thinking it was around $150 & CEP kit from CEP USA $89 bucks, It all adds up to less than a 1000 bucks and does not weigh that much more than the EXPENSIVE Euro options. Great value, great comfort, & awesome performance. I wear one over 700hrs.+ /yr and I love this set up.
