The all-new 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, softtouch 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 high-speed crashes. The other is a lower density EPP foam with rebound characteristics to address lowspeed, 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 breaks, toolfree breakaway visor bolts with integrated Allen key receiver for easy removal, and a central visor bolt hole, or B-Hole, which does double-duty as the ideal mount for P.O.V. action cameras. The new Giro Insurgent Spherical is truly optimized protection for riders redefining what is possible in progressive mountain biking.Impact Management:- Spherical Technology, Powered by Mips®Construction:- Pre-preg fiberglass for optimized resin content and reduced weight- Progressive layering with EPS outer liner and EPP inner liner- EPP chinbar liner for added impact management and weight savingsVentilation:- Channeled Stack™ ventilation at brow line optimized for goggle integrationHighlights:- Optimized airflow intake vents, internal channeling, and exhaust ports- Lightweight, absorbent, antimicrobial Ionic+™ padding- Directional snap system which combines secure fit with easy removal in case of emergency- Patent-pending Flex Gasket with exposed EPP designed to reduce certain collarbone breaks- Tool-free breakaway visor bolts with Allen key removal system- Adjustable moto-style screw-in visor with dual duty B-Hole for action camera mounting- 25mm webbing with D-Ring closure and removable Ionic+™ cover- Fiberglass shell with EPS outer liner and EPP inner liner- Integrated MIPS™ Spherical technology- ASTM-1952-DH, ASTM-2032-BMX certification- Channeled Stack™ ventilation at brow lineSpecifications:Weight:- 1,040 gramsCertification:- ASTM-1952-DH, CE EN 1078, CPSC, AS/NZS, ASTM-2032-BMX
