Science and soul. They might seem like two disparate entities - but through the 30-year history of the Giro brand, they have been brought together in equal measure. Giro benefits from world-class resources. Based in Santa Cruz, California, it's an action sports paradise - incredible waves for surfers, endless singles for bikers and coastline-lined roads for roadies.
At Giro's headquarters, you'll find over 50 different helmet testers, several 3D printers, a custom wind tunnel, and even a Therminator test head equipped with thermal sensors to test helmet venting and hole placement. Giro has a lot of products in many categories, from helmets to gloves to trunks. But each one was born out of a desire to enhance your riding experience.
