There are 4 measures of the outer shell in both versions, which was designed using the wind tunnel to engineer the best shapes and performance. Extreme attention was therefore paid to aerodynamics, with the aim of making the helmet stable even at high speeds, and to thermodynamics, to optimize thermoregulation. Airoh's technological sum is condensed in this new product, in which the AMS2 Plus (Airoh Multiaction Safety System Plus), AEFR (Airoh Emergency Fast Release) and AMLS (Airoh Magnetic Lining System) systems are profuse, which evolves, also including the magnetic cheek pads. The 8 air intakes and spoilers with integrated extractors make the fitting of Aviator 3 comfortable even in the most extreme conditions of use, as does the innovative AHS (Airoh Hydration System) integrated into the EPS. Aviator 3. Unlimited. Full Carbon 3K. HPC Carbon. WEIGHT. From 1290 g ±50 g (only for Primal graphic).
