The Giro Synthe is at the forefront of Giro's advanced helmet designs. Safety and performance are combined with an aerodynamic profile, lightweight build and the revolutionary MIPS technology. You'll be kept cool by the 26 wind tunnel vents with internal channelling, yet still slips through the air with ease across multiple head angles. The Roc Loc® Air fit system with 2-way fit tuning provides a comfortable fit and the Aero Mesh Panels have a dedicated port for securely docking sunglasses as you ride. Giro believe MIPS can redirect energy and provide more protection in certain impacts and helps provide excellent protection. The stylish Giro Synthe MIPS helmet is a high-quality helmet that will let you perform at your best, and provide you with the highest level of safety.


All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro’s MIPS-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider’s brain in certain impacts.

About Giro

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. We are and always will be a product brand. We argue for weeks about the difference of less than a millimeter in a footwear last, of a headform or the chamfered edge of a vent. We are the brand that sweats the details. From an opening price point helmet to the fit and fabric of our t-shirts to the positive click that the Switchblade makes when the chinbar is engaged. It’s that attention to detail that sets Giro apart. We 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 the smallest of details. It’s because you keep climbing. That’s why we do what we do. So as long as you keep striving for faster, bigger and better, we’ll keep making the gear that gets you there.
