Giro Aerohead MIPS

The draw: Full vision at full speed

Not a full long-tail aero helmet yet not an aero road helmet either, the Aerohead splits the difference for improved aerodynamics and reduced weight. The massive wrap-around shield offers a tremendous field of vision and increases the aerodynamics, but magnets make it easy to remove if you want a more open feel. The nearly solid design (there are only four vents) is also meant to cheat the wind to the fullest, but the trade-off is less ventilation, so it is not ideal for athletes who heat up easily. MIPS technology (Multi-directional Impact Protection System) works to isolate your head from violent movements during an impact.
