Giro Synthe II MIPS Helmet

The Synthe MIPS II is a true classic that Giro has updated for enhanced ventilation and comfort. Its compact design is aerodynamic and offers impressive ventilation power in a lightweight yet durable design, making it a favorite among cycling enthusiasts for years. It features our best technologies, including the Roc Loc 5 Air Fit system with MIPS technology, which provides improved protection against rotational forces in the event of a fall.

MIPS Spherical is a revised version of the MIPS Brain Protection System that eliminates the plastic sliding surface of the original MIPS design.

The Roc Loc Air System sets a new benchmark for fit systems. The adjustment mechanism is housed in a mini casing, allowing size adjustments to be made easily in micro increments with two fingers. Additionally, the system can be adjusted in height to ensure a perfect fit of the helmet.

In-Mold construction involves bonding the robust polycarbonate outer shell to the impact-absorbing EPS inner shell during the foaming process. This makes the helmet more durable without adding extra weight. This production process also allows for significantly better ventilation systems and vents to be formed. In-Mold helmets are therefore lighter and have much better ventilation systems compared to traditional helmets.

The Wind Tunnel ventilation is Giro's proprietary system of internal channels and active ventilation openings that direct cool, fresh air over and around your head while pushing out exhausting heat and stale air. It's a difference you can see and feel—on every ride.
