Giro Adults Helmet Sizing Chart


Giro was founded more than 30 years ago by Jim Gentes, a man with an obsession for design and answering unmet needs. That obsession led him to start making his own products, and ultimately resulted in a company committed to serving the rider through personal expression and advanced performance. Our world has changed dramatically in the past three decades, but Giro has remained steadfastly committed to serving enthusiast riders. Giro is the brand that sweats the details because they understand that riding is more than just a fleeting hobby or a passing fad. Riding is the best part of a great life and your equipment deserves attention to even the smallest of details.
