The Giro Synthe MIPS Road Helmet is the pinnacle of road helmet design, combining the performance gains of aero efficiency and light weight with great cooling power to enhance rider comfort and efficiency. 

The compact form slips through the air with ease across multiple yaw and head angles, and offers greater cooling power than the Aeon. 

This Synthe MIPS model features Multi-Directional Impact Protection System which redirects energy and provides more protection in certain impacts. 

Giro's Black Helmet has glow in the dark flash stripes to ensure your safety on the road at night.

Key features include the Roc Loc Air fit system with 2-way fit tuning and Aero Mesh Panels with a dedicated port for securely docking sunglasses as you ride.
