Bell: EVERYDAY PERFORMANCE There's no reason to skimp on comfort and protection while trying to maintain a budget. The Formula benefits from the same technologies that make our road helmets such champions of comfort and safety; this model features the MIPS impact management as well as our Float Fit retention system and innovative Sweat Guide liner. Elegant shape, fluid aerodynamics and ample ventilation ensure the Formula's place as a classy all-rounder. FEATURES Integrated MIPS (Multi-Directional Impact Protection System) - MIPS is designed to reduce rotational forces that can result from certain impacts. By integrating the MIPS slip plane into the retention system, we are able to reduce complexity and weight for a compact, better ventilated helmet that fits more closely to the head.
