Integrated eye shields eliminate the gap between helmet and eyewear that creates turbulence at speed. The Giro Vanquish MIPS builds its aerodynamic advantage around a magnetic Vivid shield developed with Zeiss optics, delivering both drag reduction and optical clarity in a single system. The shield docks magnetically for easy on/off access and flips up when you need ventilation on climbs, then locks back down when the road tilts in your favor.

TransformAir technology shapes the external shell to actively streamline airflow across the helmet's surface. Giro developed this design for time trials, triathlons, and road racing situations where aerodynamic efficiency translates directly to speed. The helmet maintains ventilation despite its slippery profile through Wind Tunnel vents that route air through internal channels, exhausting heat while the smooth exterior slips through the air. Two small vents above the eyes circulate air across your face even with the shield down.

The two-piece shell construction pairs a tough outer hardshell with a polycarbonate In-Mold Hardbody lower wrap permanently fused to the EPS liner. This approach delivers durability without the weight penalty of a single-piece hardshell design. Inside, Progressive Layering stacks two different density EPS foam liners to address both high-speed and low-speed impacts, providing energy management across a range of crash scenarios rather than optimizing for just one....
