The ultimate in ventilation control.
The Cirque X is designed for all conditions and temperatures. Level 4 venting combined with the latest evolution of ACT takes durability & protection to the pro level. ACT combines Polycarbonate plates and overlaps to create the lightest and strongest helmet available. A full wrap lower shell combined with MIPS, the rock solid quick release RCS fit system, Fidlock magnetic buckle, and X Static fabric complete the package.
ASTM F2040 / CE EN1077B
Level 4 ventilation allows you to let out stored heat on the summit or preserve it on the chairlift when you are the only person crazy enough to still be out there. You have full control over your ventilation and offers more open airflow than any other helmet on the market.
