Giro Insurgent Spherical Matte Bike Helmet Black. Insurgent sets a new standard for full-face helmets. Made of fiberglass and equipped with Spherical technology that uses two separate coatings to help control impact forces. The material and density of the inner and outer liners can be optimized with progressive layers to help manage a wide range of impact forces. Also, despite the added features and protection, it has 50% more cooling efficiency than the Disciple Mips, the most ventilated helmet up to now.
