The material and density of the inner and outer liners can be optimized with Progressive Layering to help manage a broad range of impact forces: the Insurgent features an outer EPS layer (to address high-speed impacts) and an inner EPP layer (with rebound characteristics designed to handle slower speed falls.) When you combine the benefits of Progressive Layering with the market-leading Mips Brain Protection System, which can help redirect rotational energy away from the brain, you get more comprehensive protection. HOW DOES SPHERICAL TECHNOLOGY WORK? Developed at the Bell+Giro Dome laboratory in partnership with Mips, Spherical Technology’s unique Ball-and-Socket Design redirects impact forces, bringing market-leading design, performance and brain protection together without compromising comfort, ventilation, weight or style.
