A staple helmet amongst Enduro World Series and Red Bull Rampage riders, the Giro Insurgent Spherical Bike Helmet protects the noggins of some of the most prolific and progressive mountain bikers in the world. Engineered to be lightweight, well-ventilated, and above all, safe, the Insurgent Spherical is confidence incarnate. By utilizing different densities of EPP and EPS foam layers, a patent-pending Flex Gasket along the lower edge of the helmet, and Spherical technology, this helmet is your ticket to leveling up on trail.

Construction

   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.
