The Insurgent Spherical Helmet features the superior protection, comfort, and confidence you desire when ripping your favorite downhill trail. This full-face helmet combines an EPS outer layer and an EPP inner layer to create a ball-and-socket design, known as Spherical Technology, to manage the force of impact during a crash. The Insurgent Spherical is designed to keep your head as cool as possible during even the hottest rides, using optimized airflow intake vents, internal channeling, and stack ventilation to increase cooling power.
