FUSION IN-MOLDING POLYCARBONATE SHELL, PROGRESSIVE LAYERING, AND EXPOSED POLYCARBONATE ROLL CAGE - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. The process of engineering a helmet liner with variable EPS foam densities to better manage the transfer of energies after some impacts. MIPS-EQUIPPED AND FLOAT FIT RACE (INTEGRATED WITH MIPS) - MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts. Custom-fit at the highest performance, Seemlessly integrated with MIPS, and offers three-way adjustability: height, pad width, and tension. X-STATIC AND XT2 PADDING, NO-TWIST TRI-GLIDES AND SWEAT GUIDE - Quick-drying materials, woven with real silver fibers. Quick-adjust fasteners that help keep straps flat and properly positioned. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear. DUAL-FLOW VENTILATION, INTEGRATED BREAKAWAY CAMERA MOUNT, AND 4-POSITION ADJUSTABLE VISOR - Actively ushers cool air over the head and regulates temperature by drawing cool air into the intake ports and circulating it through a matrix of air channels. A seamless camera mount, requiring no zip ties or tape, is engineered to break away upon impact to reduce the risk of injury. Adjusts for maximum comfort and steeze.
