The Giro Vanquish is much more than a variation on the original Air Attack Shield. The Vanquish is an entirely new design, using -among other things- a clever stepped outer shell profile that Giro calls "TransformAir". This shape convinces the air that the helmet is much longer than it actually is, producing impressively low aerodynamic drag similar to a long-tail TT helmet. The interior of the Vanquish still features deep, uninterrupted Wind Tunnel channels that keep the wearer cool, while a MIPS (Multidirectional Impact Protection System) liner allows the helmet to better absorb the energy of an oblique impact. The MIPS liner is integrated into the RocLoc Air fit system, reducing weight and bulk while preventing overheating. The 4-piece HardBody exterior shell and dual-density Progressive Layering construction keeps the crashworthiness of the Vanquish up to standards without adding extra weight. Over 50 different test fixtures at Giro allow the engineers to refine the design and ensure each and every Vanquish MIPS helmet will perform to their very high expectations. They even use an on-site wind tunnel to ensure excellent cooling performance.
The Vanquish also features a magnetic Vivid Shield visor produced by Zeiss Optics for excellent optical clarity and eye protection. This shield can be removed on the fly and reattached inverted with magnets when not needed. Cool, huh? If the wearer prefers regular sunglasses, there are eyeglass grippers in the front vents for storage. The interior padding boasts an antimicrobial treatment that keeps the Vanquish fresher for longer. 3 sizes will fit a wide range of riders looking for an aero advantage, or just a quieter helmet on windy days.
