Giro Aerohead MIPS Helmet Small Matte White/SilverGiro’s Aerohead MIPS Helmet was designed for speed and cooling efficiency during triathlons and time trials: its aerodynamic profile is completed by a lightweight Polycarbonate shell construction (with EPS liner). The 4 Wind Tunnel ventilation and internal channeling system keeps you cool and dry, while the Multi-directional Impact Protection System (MIPS) helps redirect impact energy in certain collisions to keep you safe. An innovative ZEISS Optics wrap-around eye shield ensures your field of view stays clear and focused, and the magnetic anchor that holds it in place allows you to easily flip it up or remove it when not in use. The Aerohead MIPS Helmet comes in Small (20”-21.75” / 51-55cm), Medium (21.75”-23.25” / 55-59cm), and Large (23.25”-24.75” / 59-63cm) sizes, and is available in Matte Black/Titanium, Matte Silver/White, Matte Grey Firechrome, and Matte White/Citron.768686729188
