Giro's Vanquish MIPS Helmet reaches the zenith of high-performance road cycling helmets. Giro spent countless hours studying the science--and art of mastering--airflow, which dictates the helmet's shape and vent designs. Months of aerodynamic development, dozens of prototypes, and extensive feedback from pros inform the Vanquish MIPS, Giro's ultimate aero road helmet. As an evolution on the popular Air Attack, this model features an innovative TransformAir design that actively streamlines airflow. An aerodynamic "cliff" tricks the air by reducing drag and provides the aerodynamic efficiency of a full teardrop helmet in a profile that is more comfortable and versatile in a variety of head angles. Four Polycarbonate Hardbodies make the helmet lighter, more aerodynamically efficient, and durable. No detail went unnoticed and even the helmet straps have been tuned with aerodynamics in mind. Giro's proprietary Tri-Glides system allows the helmet's featherweight webbing to lie flat against your face, increasing comfort and reducing aerodynamic drag. With all of those aero developments, it might be easy to forget proper ventilation, leading to hot heads on climbs and during summer months. But not so on the Vanquish. Wind Tunnel ventilation allows air to flow smoothly across the top of your head to deliver optimum cooling inside the entire helmet without increasing aerodynamic drag. Inside the Vanquish is an EPS liner with a progressive layering of multi-density foam that saves weight and allows the Vanquish to help absorb a wide range of impact energies. The renowned RocLoc Air system seamlessly integrates with MIPS Technology to enhance comfort and cooling power while providing an additional measure of impact diffusion in certain impacts. All Vanquish helmets include a Vivid shield making the helmet even faster by streamlining airflow. The road-tuned Vivid lens increases contrast and definition to bring road obstacles in stark relief while keeping colors true-to-life....
