The Giro Insurgent Spherical is the truly optimized protection for riders redefining what is possible in progressive mountain biking.

The Giro Insurgent™ Spherical is focused on delivering the protection that our top riders demand, from the Enduro World Series to Red Bull Rampage. Giro’s 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 a 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.

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.
