evo.com | Giro Bike Helmets > The Giro Insurgent Spherical Bike Helmet is what Rampage riders and EWS racers strap on when the stakes are high - and it's not hard to see why. It's light, tough, and offers superior protection, with MIPS(R) Spherical Technology ball-and-socket construction redirecting impact forces more effectively than standard MIPS slip planes. The Roc Loc(R) Air DH fit system suspends the helmet slightly off your skull to keep air moving underneath, and at 1040g you might just forget you're wearing it at all. In-Mold Construction In-mold construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets. CE EN 1078 Optimized Front Intake Vents Giro engineers designed precise placement and shape of intake vents to optimize cool air flowing over riders' heads. MIPS(R) Spherical Technology Spherical Technology's ball-and-socket design; powered by MIPS(R); helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin. Roc Loc(R) Air DH Fit System This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling; as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull; Roc Loc Air DH allows cool airflow to pass directly over your head; further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 5; allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand. | Giro Insurgent Spherical Bike Helmet 2026 - M/L in Blue Size Medium/Large | Plastic
