Giro Synthe Road Helmet

The Synthe is the pinnacle of road helmet design, combining the performance gains of an aerodynamic profile and light weight with great cooling power to enhance rider comfort and efficiency in road rides and races. The compact form slips through the air with ease across multiple yaw and head angles, and offers greater cooling power than the Aeon. 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.
Roc Loc Air Fit System
This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc Air allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 5, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
Wind Tunnel ventilation system
Giro helmets are developed utilizing the proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet’s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider’s head while forcing heat and stale air out. It’s one of the most effective cooling systems available, and a difference you can feel every time you ride.
X-Static Padding
X-Static padding contains a fiber made with layers of pure silver that is permanently woven into the fabric. Silver has natural anti-microbial performance that helps to reduce odor and regulate heat, so your helmet stays fresh and comfortable, naturally.
