The Z9 modular design offers the best of both worlds... full face protection and open face breathability with the push of a button. A removable and washable comfort liner keeps your helmet fresh. Comfort is maintained during those long afternoon rides with a padded chinstrap, plus the excess strap is secured with a snap so you can ride without distractions. The contoured breath deflector reduces fogging, while multiple air vents including one closeable vent on the chin, two screen vents on the chin, and one large closeable forehead vent keep your head cool. The shield is mounted using the unique G-FORCE Sure-Fit metallic hardware. This adds safety in the event of an impact because the shield is more securely fixed to the helmet in comparison to other designs. Also standard is the new Dynamic Shield Lock, which keeps the shield closed even in the strongest of updrafts.
