Key Features: Mips: Flex spherical + mips - comprehensive energy management - flex spherical enhances our ability to address high-speed impacts, low-speed impacts, as well as rotational impacts. Think of it as \"comprehensive protection,\" with the added bonus of being able to design better helmet ventilation.,Construction: Fusion in-mold polycarbonate shell - a process pioneered by bell bonds the helmet\'s outer shell to the eps foam liner to create a sturdier helmet.,Progressive layering: the process of engineering a helmet liner with variab,le eps foam densities to better manage the transfer of energies after some impactsVisor: Goggleguide adjustable visor — accommodates both goggles and glasses,Number of vents: 18 helmet vents, 4 brow ports,Interior/liner type: Sweat guide pad design pulls moisture away from the brow pad and away from eyewear,Ventilation type: Overbrow ventilation features intake ports on the brow of the helmet to usher in cool air and push it through the air-channel matrix for full-head ventilation,Fit system: float fit - a minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with mips)  ,.
