Item # GIR00IG

Go fast, look fast.

Giro's Vanquish is a beast of an aero helmet. It's totally refined to help you go faster with zero compromises. Giro designed the helmet with a shield so you can forgo your typical sunnies, and the helmet is even faster when using the shield as it better streamlines airflow. The replacement Vanquish Shield is available if you happen to scratch or lose the originals or if you just want to match your team kit a little better. Using Carl Zeiss lenses, the road-tuned Vivid shield increases contrast and definition while keeping colors true to light. The shield attaches to the helmet via magnets and can be flipped up and docked on extended climbs or in low light. Choose from the colors Onyx, Emerald, and Ember.

What do you think about this product?



Does the "Clear Silver" have a silver mirror tint to it? Or is it really clear? I'm trying to replace the one that came with my helmet. "Silver" sounds right, but maybe it was the Onyx. Do you know if the Onyx comes standard on any helmets? I have the Dazzle colorway.


Can you please clarify if the Onyx shield is the clear one? I am looking for the shield that can be used during very low light situation (I ride mostly at night). Thanks!

Hi Andre, the Onyx lens is actually a darker lens made for full sun. We also have the Ember and the Emerald lens available and they are made for mildly cloudy weather.
