Giro: CONFIDENCE TO COMMIT The Giro Insurgent™ Spherical is focused on delivering the protection that our top riders demand, from the Enduro World Series to Red Bull Rampage. Our engineers maximized the intake points for cool, fresh air while optimizing the exhaust ports and connecting it all with deep channels. A lightweight, soft-touch and absorbent pad set includes a brow pad with dedicated flange to route sweat away from your eyes. Two different cheek pads are included with each of the three sizes, allowing for a customizable fit, and are secured via a directional snap system allowing for easy removal in case of a crash. At 1,040 grams in size M/L, the Insurgent is 200 grams lighter than the Disciple™ Mips despite adding features including the advanced protection performance of Spherical Technology™. Insurgent Spherical utilizes a pair of foam layers that work like a ball and socket to redirect impact energy in a crash. One layer is EPS, which is well suited to highspeed crashes. The other is a lower density EPP foam with rebound characteristics to address low-speed, roll-around-in-the-dirt-type spills. Additional features include a patent-pending Flex Gasket along the lower edge of the helmet, designed to reduce the role a helmet can play in certain collarbone impacts, tool-free breakaway visor bolts with integrated Allen key receiver for easy removal, and a central visor bolt hole, which does double-duty as the ideal mount for P.O.V. action cameras. The Giro Insurgent Spherical is truly optimized protection for riders redefining what is possible in progressive mountain biking.SPECSSpherical Technology™Mips® Brain Protection SystemProgressive Layering with EPS outer liner & EPP inner linerEPP chinbar linerPre-preg fiberglass shellStack VentilationOptimized airflow intake vents and channeled ventilationPatent-pending Flex GasketAdjustable moto-style screw-in visorAdded central visor bolt hole enables action camera mounting spaceTool-free breakaway visor boltsDirectional snap system for removable cheek-padsTwo sets of cheek-pads for variable thickness adjustabilityIonic+ anti-microbial padding25mm webbing with D-Ring buckleCertifications: ASTM-1952-DH, CE EN 1078, CPSC, AS/NZS, ASTM2032-BMX 1,040 grams size M/L (CPSC) CONSTRUCTIONIn-Mold constructionFIT SYSTEMRoc Loc® Air DHVENTILATION20 Vents withinternal channelingWind Tunnel™ cheek pad ventilation
