The Synthe™ is the pinnacle of road helmet design. It offers impressive cooling power, minimal weight, supreme fit and streamlined aerodynamic efficiency. It is a true synthesis of all features a modern rider wants in a high performance road racing helmet.
The difference is clear in the wind tunnel—our extensive testing reveals that the Synthe is nearly as efficient as the fastest time trial helmets. But the Synthe’s greatest attributes are comfort and ventilation. At it’s heart you’ll find our Roc Loc Air fit system. Micro adjustments allow you to custom tune tension and fore-aft tilt with one hand and a patented design suspends the helmet over the top of the skull, allowing airflow to pass freely over your head. Cooling power is further boosted by elaborate internal channeling and a series of massive vents; the Synthe sets a new bar for ventilation.
You no longer need to choose between aerodynamics and cooling power—with Synthe you get everything, all wrapped up in a compact and sleek silhouette.

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
Giro helmets are developed utilizing our 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 the most effective cooling system available, and a difference you can feel every time you ride.
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.
